The Best VM Monitoring Tools and Software

A virtual environment offers a way to extend the utilization of onsite resources. It’s a common solution on most business networks thanks to the ease of using VMWare and Microsoft’s Hyper-V virtual machine (VM) software. However, when it comes to resource monitoring, the extra layer of traffic that is inevitable with VM setups can make resource mapping complicated. Once your business grows, keeping track of that VM solution can quickly get out of hand.

Virtual machine monitoring helps you stay on top of resource issues when allocating resources from one virtual machine to another. Network traffic issues are inevitable when making remote resources available instantly and locally. You need to track demand and adapt resources to keep network users happy. Capacity planning is a key part of VM management, and monitoring utilization helps you stay ahead of demand and keeps response times low.

The best VM monitoring tools and software

We have put together an analysis of the best VM monitoring solutions and produced a list of utilities that you should consider when shopping for software.

These VM monitoring tools are industry leaders and will save you time when tracking your virtual device environment. The following section gives you information on each of these VM monitoring tools.

1. NinjaOne (FREE TRIAL)

NinjaOne is a remote monitoring and management (RMM) package that is delivered from the cloud. This system includes automated monitoring services that track the performance of VMware and Hyper-V implementations.

Key Features:

• Monitors VMs: Hyper-V and VMware
• Part of an RMM: Monitors networks, servers, services, and software
• Part of Endpoint Monitoring: Notes host resource availability

Why do we recommend it?

NinjaOne is a comprehensive package that isn’t limited to monitoring VMs. It will also monitor networks, servers, and applications other than virtualizations. This RMM can monitor cloud services as well as on-premises resources. This system has a high degree of automation to improve the productivity of technicians and provide value for money.

The package implements a discovery service that populates the monitoring console with all of the virtualization instances that it identifies. The discovery process repeats continuously to spot new instances and changes in the configurations of existing implementations.

The inventory of VMs includes static details, such as the brand, the version number, and the license conditions. The tool also records the most recent continuous uptime period.

The types of performance metrics that this package assesses include those related to the physical hosts, such as power, battery status, temperature, and fan speed. Looking at the interaction between the virtual host and its supporting server, the system records memory, CPU, and disk usage with respect to the total availability of those resources.

The system shows VM allocations and activity that enables a network administrator to adjust allocations according to heavy demand or inactive units. All of the statuses can be stored as reports and so can historical usage data.

While noting total available resource capacity and current usage, the system is able to trip thresholds, which can be adjusted. These raise alerts if they are crossed. The purpose of the thresholds is to give advanced warnings about possible resource shortages.

VM management functions in the package include the ability to create, store, and delete snapshots. Administrators can also use the NinjaOne interface to start, stop, and reset VMs. All of the functions of the NinjaOne system can be applied equally to Hyper-V and VMware and the screens can show statistics from both simultaneously – if anyone uses both bands on one site.

Who is it recommended for?

This system is available in a multi-tenanted architecture for managed service providers (MSPs). This enables the MSP to set up sub-accounts to keep the data of their clients separate. The cloud-based package includes a Help Desk ticketing system, which is useful for both MSPs and IT departments. An IT support team could also use the RMM and its Help Desk service.

This cloud-based system is able to manage multiple sites simultaneously across the internet through the installation of an agent on each site. You can assess the NinjaOne package with a 14-day free trial.

2. Paessler PRTG Network Monitor (FREE TRIAL)

Paessler produces a great network monitoring solution that covers both network device monitoring and traffic analysis. This service integrates functions to track VM performance. Although Paessler PRTG Network Monitor is a full-service network monitor, it does come in a free version. Paessler sets its prices on the number of sensors that the system monitors. A “sensor” is a service aspect, such as network speed, or a monitoring point, such as a port. PRTG is aimed at large networks, but the free version would be suitable for small businesses.

Key Features:

• Monitors Multiple Virtualizations: VMware, Hyper-V, and Citrix
• Full Stack Monitoring: Also monitors networks, servers, services, and cloud platforms
• Correlates VM Activity with Server Resources: Checks on CPU, memory, and disk usage

Why do we recommend it?

Paessler PRTG Network Monitor is a bundle of monitoring tools that cover software and servers as well as networks. This full-stack capability is great for monitoring the activities of virtualizations. The tool has specific monitoring sensors for tracking the performance of Hyper-V, Citrix, and VMware as well as cloud platforms and containers.

The VM application monitoring capabilities of Paessler PRTG extend to the following platforms:

• Citrix Xen
• Microsoft Hyper-V
• VMWare
• Parallels Virtuozzo Containers
• Amazon EC2

The capabilities of the monitor give you the ability to monitor your whole network with this tool, not just the virtual environment. The underlying network traffic analysis works on typical messaging systems that are part of the firmware of the major network equipment manufacturers. Physical network devices are monitored via the SNMP system. PRTG extends network monitoring across sites and into the cloud.

Server performance monitoring focuses on CPU load, disk usage, and network transmission speeds. Physical aspects of host machines that PRTG monitors include the server’s temperature, current power consumption, battery voltage, and fan speed.

Those server metrics lead to service highlighting that will warn you of overloaded servers. With this knowledge, you can redistribute VMs across servers to gain a fairer load and better performance. You can set your performance warning levels across server attributes. These custom alerts let you see which servers are overloaded. Warnings appear in the dashboard, but you can also have them sent by SMS, email, or through an API.

Both the dashboard and notifications can be filtered to create custom views with limited controls for different team members. You can send notifications to different recipients according to warning source or severity.

Who is it recommended for?

Paessler PRTG is a software bundle for Windows Server. However, if you don’t have that operating system, you can opt to access the service as a SaaS package. The tool’s price depends on how many sensors you want to activate and if you only use 100, the system costs nothing.

The free PRTG is limited to 100 sensors. You can also get a 30-day free trial of the full system, which has no limit on the number of sensors that you can monitor.

3. eG Enterprise VM Monitoring (FREE TRIAL)

The eG Enterprise monitoring system, from eG Innovations, covers VMware vSphere, Citrix XenServer, Microsoft Hyper-V, Oracle VM Server, Red Hat Enterprise Virtualization, AIX LPARs, Solaris Container virtualizations and their supporting infrastructures. The big selling point behind eG Enterprise’s VM monitoring is that checking on server memory and CPU utilization doesn’t give you the whole picture of virtualization health. You also need to see issues that arise on the network, on the storage server, in the database, or within the virtualization platform software.

Key Features:

• Monitors Multiple Virtualizations: VMware, Citrix, Hyper-V, Nutanix, Oracle VM Server, Red Hat Enterprise Virtualization, and AIX LPARs
• Also Monitors Container Technologies: Docker, Red Hat OpenShift, and Kubernetes
• Relates VMs to Applications: Documents the application and the supporting VM together
• Root Cause Analysis: Identifies whether the VM, the network, the server, or the application is to blame for performance problems

Why do we recommend it?

eG Enterprise VM Monitoring has the edge over the SolarWinds tool in that it can monitor more hypervisor brands. It has the capability to monitor VMware vSphere, Citrix XenServer, Microsoft Hyper-V, Oracle VM Server, and Red Hat Enterprise Virtualization. It can also track containers and AIX logical partitions.

The interface for the system is browser-based. It includes graphical displays, lists of live data and alerts, and sections to assist with capacity planning. The links between resources are mapped in the dashboard when you install the system. eG Enterprise is particularly strong at identifying resource interdependence. Examples of these relationships include application and VM platform interaction and the underlying physical infrastructure needs of the VM software. That baseline informs the rule base of eG Enterprise on alert conditions that impair the performance of the environment.

Not only will you receive alerts that the response times of a particular VM is slow, for example; you will be notified if the database is overloaded and whether that is causing a particular VM to perform poorly.

The ability to identify the root cause of performance issues at the lowest levels gives eG Enterprise its power. This means you don’t have to waste time back-chaining through stack layers to work out what is going wrong. Multi-vendor environments are common and eG Enterprise unifies the monitoring of the provision stack for a wide range of possible combinations of virtualization systems. So, you will see each of the platforms individually, but the underlying resources that support several environments are monitored for total demand, not on a platform-by-platform basis.

The benefit of the unified stack approach is that it lets you see which VM hogs resources and makes the going tough for the rest of the network. The dashboard includes a great color-coded stack diagram that shows the coexistence of platforms at the supporting levels. EG calls this its in-n-out monitoring. The outside view shows all of the VMs in bands sized in proportion to each service’s resource usage. The inside view shows each layer of the stack with each VM’s usage at that level side by side, again, in proportion.

Another nice visualization feature of eG Enterprise is a workflow-style diagram that traces all of the resources needed by a virtual machine and, in turn, the resources that each supporting feature requires. Each element in the chain shows its status. So, if one of those nodes shows an alert, then you know exactly where to go to get that VM back in good health.

Who is it recommended for?

If you use a virtualization system that isn’t covered by the SolarWinds tool, you should consider eg Enterprise. Another advantage of this tool is that it will run on Linux as well as Windows Server and it is also available as a SaaS package. The tool’s VM activity visualizations are hard to beat.

The VM monitoring market is crowded with some very powerful tools provided by some huge software houses. The eG Enterprise package has some handy features that many of its rivals lack. A big attraction of the eG Enterprise monitoring service is that it is priced per physical server, so you can monitor as many virtualizations as you like without worrying about cost. There isn’t a free version of eG Enterprise, but you can access a 30 day free trial to asses your network requirements.

Key Features:

• On-Premises and Cloud VMs: Hyper-V, VMware, Nutanix, and Azure VM
• Registers VM to Servers: Monitors load on each virtual server
• Tracks Resource Usage: Correlates physical server resource usage with virtual system activity

Why do we recommend it?

Site24x7 provides packages of monitoring tools from its cloud platform and these all include network and server monitoring. The platform also provides application performance monitoring, including virtualization monitoring for VMware, Hyper-V, and Nutanix and also Docker containers. The system simultaneously checks resource usage on servers and identifies the root cause of virtualization problems.

This monitoring system is offered in several specialist Editions, which cater to regular businesses, MSPs, and web-based enterprises. Its competence covers servers, networks, and applications – a combination that is ideal for the monitoring of virtualizations. The system is capable of monitoring Microsoft Hyper-V and VMWare virtualizations onsite and AWS and Microsoft Azure-based Cloud servers.

As well as covering virtualizations, Site24x7’s monitoring package covers supervision of containers run by Docker or Kubernetes. It is also able to monitor the Nutanix hyper-converged infrastructure system.

The console for the service is accessed through a browser and you can also install an app on mobile dives to get access. The fact that the system is based on remote servers liberates its abilities so that it can monitor networks anywhere in the world. Tools in the service include live status monitoring and analysis of performance based on historical data.

The system begins its service by discovering and logging all of your infrastructure. It will detect your virtualizations and map all contributing resources. Once that initial discovery phase is complete, the system continues to check on the topology of your network and virtualizations, automatically adjusting its records if you change any aspect of your implementation.

The visualization screens are very clearly set out. The simplicity of each monitor for VM is helpful because it gives you great visibility on what can sometimes seem to be an extremely complicated technology.

The system view is spread out over several screens and you can drill down to see the mappings of VMs to hosts, the performance of each server, and the activity on the network that delivers your virtualizations. Statuses are color-coded for instant problem identification and resource alerts give you a constant status update on each contributing element of your virtualization implementation.

You can customize alert levels and head off any potential threat to your VM environment before a resource shortage occurs. Reports in the package include SLA management reporting and resource utilization logs.

Analysis features help you remap VMs to hosts if any single server looks overloaded. You can use the reports in the pack to demonstrate resource requirements to stakeholders.

This is a great tool for team-driven VM monitoring. It is charged for on a subscription basis and you pay for the number of servers that you need to monitor, not the number of technicians that you want to have access to the monitor. Price plans for infrastructure monitoring are very scalable. You take out a Starter plan, which covers up to 10 servers and add-on capacity if you need to watch more servers.

Who is it recommended for?

Site24x7 provides packages of its modules that are sized to be suitable for small businesses. Larger businesses pay for extra capacity add-ons. The problem with this structure is that bigger companies can end up with a subscription charge that is a great deal higher than the advertised price.

Virtualization monitoring capabilities are offered as part of the Site24x7 Infrastructure package. This is a very comprehensive system that is suitable for large corporations. However, small enterprises can use it too. What’s more, Site24x7 is free to use if you only need to monitor up to five servers. So, Site24x7 is a good choice of all business sizes. You can get a 30-day free trial of the system. Your subscription will automatically switch over to the Free edition at the end of the trial period if you choose not to pay. That service can be upgraded to the wider paid service at any time.

5. ManageEngine OpManager (FREE TRIAL)

ManageEngine OpManager monitors networks and servers, which is a great combination of services if you want to monitor virtualizations.

Key Features:

• Monitors Multiple Virtualization Brands: VMwre, Hyper-V, Citrix, and Nutanix
• Manages VM Sprawl: See which VMs are almost inactive
• VM Maps: discovers and depicts the relationships between virtual hosts and VMs

Why do we recommend it?

ManageEngine OpManager provides monitoring for servers and networks. Its remit extends to the supervision of virtualization activity with the ability to track Citrix, VMware, Hyper-V, and Nutanix systems. The combination of server and network monitoring works well in conjunction with VM monitoring because it provides immediate root cause analysis.

The system is able to monitor virtualizations created with:

• VMWare vSphere and ESXi
• Microsoft Hyper-V
• Citrix XenServer
• Nutanix HCI

The service includes monitoring systems to watch over the performance of operating systems, network interfaces, and server resources, such as CPU availability, memory, and disk space. So, it has all of the supporting infrastructure for hypervisors covered.

The OpManager system includes a system discovery service. This extends to the entire network, identifying all network devices and endpoints and logging them in an inventory. The service performs the same task for virtual infrastructure.

The VM tracking system in OpManager identifies all of your virtual servers and discovers all of the links through virtual switches to the dependent virtual machines. Both the physical and virtual network discovery services are constant, so if you make any changes to your infrastructure, OpManager will instantly spot them and adjust its system maps.

The ongoing VM monitoring of OpManager identifies the resource usage of each VM on a virtual server – particularly that vital metric of memory usage. You can see which VM is eating up the most available memory on a system and watch each VM’s performance with live usage statistics. This enables you to head off disaster by altering allocations or examining why a particular VM is using so much memory.

The tracking of physical server resources allocated to a hypervisor is also going on at the same time as the monitoring of virtual system activity. So, you can see whether one particular virtual server is consuming a lot of memory or CPU. The OpManager service tracks all activity on each server so you will be able to spot if a completely unrelated process could be about to endanger the successful performance of your virtualizations by consuming all available server resources.

The OpManager system will monitor every level of your virtualization – both within the hypervisor and beneath it and also watch all of the services that run on top of them. These tasks create a lot of live information, all displayed on different screens in the system dashboard, which would be impossible to watch manually.

Fortunately, OpManager includes a system of performance thresholds and each will trigger an alert if a resource runs short or an element’s performance drops. These alerts can be forwarded to technicians as emails or SMS messages. So, no one needs to sit and watch the screens because OpManager will take care of monitoring the regular performance of your physical and virtual infrastructure.

Who is it recommended for?

This package is available in a limited Free edition but that doesn’t include VM monitoring. However, the standard package is sized to suit small businesses and there are capacity expansions and higher plans to suit mid-sized and large organizations. The software for OpManager will run on Windows Server, Linux, AWS, and Azure.

OpManager is delivered as on-premises software that is available for Windows Server and Linux. ManageEngine offers the system on a 30-day free trial.

6. LogicMonitor

LogicMonitor is a network performance management system, but it integrates the monitoring of virtual server environments. So, you can use it as a system-wide monitor or just limit it to monitoring your virtual machine implementations. The LogicMonitor system offers VMware vCenter monitoring, ESXi hosts monitoring, and also covers individual VMs, including ESX and ESXi.

Key Features:

• Monitors Major Virtualization Brands: Hyper-V, VMware, Citrix, and Nutanix
• Cloud Virtual Server Monitoring: AWS and Azure
• Virtualization Mapping: Based on an autodiscovery cycle

Why do we recommend it?

LogicMonitor watchers over physical and virtual assets, including Hyper-V, VMware, and Citrix systems. The tool can also track the performance of the AWS and Azure cloud platforms. This package is able to simultaneously watch the VMs, the resources that they rely on, and the applications that run on top of them.

LogicMonitor performs Microsoft Hyper-V performance tracking at both the hypervisor and individual VM levels. This system can also interact with Citrix XenServer technology.

The software for this monitor is accessed in the cloud. It is platform-neutral and can monitor cloud-provided VM services as well as onsite systems. However, it’s not an utterly offsite implementation because you need to install collectors on your servers and network devices. These collectors route through your gateway up to the central LogicMonitor server. All communications over the internet are encrypted, as is stored data on the LogicMonitor server. Information is decrypted in real time when accessed through a valid user account, which requires access credentials.

The monitor starts with an autodiscovery process, which maps your entire network, including your XenServer, VMWare and Hyper-V implementations. The system extends to Amazon cloud servers and Microsoft Azure.

The underlying technology of VM systems engenders a wide range of monitoring topics. In fact, to keep a VM system running, you need to watch hardware, operating systems, network performance, application and service execution, and, above all, resource utilization. You’ve got virtual switches to contend with, and you need to make sure storage and application servers do not overload and are accessible at acceptable delivery speeds. The LogicMonitor dashboard covers all of these issues.

Hardware performance attributes that the VM monitor tracks include the overall health of your servers. They focus on memory usage, CPU load, disk latency, disk data rates, disk IO/ s, and VMkernel swap rates to keep the service level chugging along.

System alerts can be sent out by email, SMS, or Slack notifications. You can specify which team members receive alerts by classification and by source. If you outsource part of your virtual environment, the support team of the provider can be notified automatically. The dashboard can be tailored according to role as well, so you can safely share consoles with all team members, even junior staff. A data-only view can be created to let finance and c-Suite members view events in the VM system.

Who is it recommended for?

LogicMonitor offers editions that match the needs and the budgets of small, mid-sized, and large organizations. The full-stack monitoring capabilities provide all the tools that any business would need to ensure that all systems are running smoothly. This is a reliable brand with an excellent support team.

LogicMonitor is not free, but you can get a 14-day free trial to give it a spin. The package is available in three editions: Starter, Pro, and Enterprise versions. This scalability means that LogicMonitor is suitable for all sizes of businesses.

7. Veeam One

Veeam One monitors network resources and examines the system utilization by VMWare vSphere and Hyper-V virtualization implementations. The monitoring power of the tool extends to cloud-based services. Veeam is particularly strong on system backup and recovery. The Veeam One service was designed to integrate with the company’s Backup and Replication Manager.

Key Features:

• Focused on Backups: Will backup Hyper-V and VMware environments
• Forecasts Resource Requirements: Performs trend analysis
• Automated Responses: Links remediation actions to alerts

Why do we recommend it?

Veeam One offers a free edition that provides just about all of the features of its paid version. Both package include VM monitoring for Hyper-V and VMware. The platform is a cloud-based system and can track assets anywhere. You get a correlation between virtualization performance and the availability of physical resources.

The Veeam One system uses real-time monitoring round the clock. Those monitors check on 200 preset sensors, and you can add your own customized monitoring conditions and alert rules. A capacity module gives you insights into ongoing resource utilization as well as trend analysis based on historical data. The data gathering components cover all of the physical infrastructure that supports the virtualization and checks for capacity limit warnings.

You don’t have to rely on the interpretations of the dashboard visualizations and reports provided by Veeam One because you also get access to raw data. This enables you to build your own customized reports, apps, and alert rules.

Veeam One is a paid product. However, there is a free version. Veeam One Free includes all of the virtual machine monitoring capabilities of the paid system. There is no capacity limit on the free version of the system, which is rare in the industry. Veeam One Free doesn’t have the capacity functions included in Veeam One, in any case. The free version also lacks charge tracking and billing features.

Both the free and paid versions display alert notifications on the screen. These can also be sent by email, but only paid users can customize alert conditions.

Who is it recommended for?

Veeam provides a backup and recovery service, which isn’t free, so you would have heightened interest in the Veeam One package if you are also in the market for a backup system because the two services slot together. The free Vaan One is appealing to small businesses.

Veeam One is particularly effective for customers of the company’s backup server software. Tenant tracking also makes this an excellent choice for service providers, both for cloud storage provision and for software-as-a-service. If you think you would be better served by the full, paid Veeam One service, you can test it on a 30-day free trial.

8. Quest Foglight

Foglight is a system monitoring system that has versions for cloud monitoring and VM environment management. The system works with VMWare and Hyper-V, focusing on the information gathered at the vSwitch, combined with physical performance data from the server.

Key Features:

• Monitors Multiple Virtualization Types: VMware, Hyper-V, and Citrix
• Multiple Technologies: Also monitors containers, cloud platforms, and physical servers
• Balance Workloads: Include VMs in workload distribution

Why do we recommend it?

Quest Foglight is similar to SolarWinds SQL Sentry because it combines database and virtualization monitoring. You can track the performance of VMware, Hyper-V, and OpenStack systems with this tool, cloud platforms, including AWS, Azure, and GCP, and OpenShift, Docker, and Kubernetes containers. The system also observes activity on servers running Windows and Linux.

The system sets itself up through an autodiscovery function. It identifies servers and their client virtual machines, and it examines the traffic that passes between them to highlight network performance. The traffic analysis data gathering section of this tool examines packet-level data to identify which VMs and applications generate the most traffic.

The Foglight system can also monitor Citrix XenApp and XenDesktop environments. The application monitoring dashboard gives you a display of all the elements in the Citrix VDI stack, highlighting strained infrastructure that could impact performance delivery. The system cleverly maps the topology of your virtual environment to help visualize the locations of each VM and monitor the physical traffic flows between servers and VMs.

The monitor extends into management functions as well. You can set it to dynamically adjust resources allocated to each application or VM to account for underutilization or over-capacity in different areas of the network. The monitor dashboard gives you a range of views on Citrix user session activity from overall VM count summaries through to application activity.

The Foglight monitoring system closely tracks NetScaler performance and network latency. The load on physical devices and virtual switches are other considerations. The Foglight monitor identifies inactive VMs and lets you remove zombie processes to free up resources. This is an excellent feature because, unfortunately, the VM environment is prone to hanging processes and abandoned sessions that leave locks on resource allocations behind.

The Foglight system explores and stores data to build up a testbed. The dashboard will show trend and variant performance and isolate data for each hardware element of your system. This helps discover bottlenecks and resource misallocation.

The data patterns and regular usage statistics give you a capacity planning function. With this tool, you can identify where to adjust the allocation of resources to improve performance and work out the effects of increased demand. The Foglight monitor includes predictive capabilities that suggest actions to resolve alert conditions. This will also work with live data to help adjust network utilization on the fly.

If you operate a multi-vendor environment with both VMWare and Hyper-V software operating onsite, you can unify your monitoring and management tasks in one place with the Foglight system. The monitor extends to cloud storage, so you can vary capacity by adjusting extra offsite provisions, such as additional storage.

Who is it recommended for?

This is an on-premises package that will run on Windows or Linux. The tool simultaneously watches over VMs and the servers that support them. It is good at providing alerts for resource shortages and performance problems so you get to see exactly which asset is causing problems.

Quest Foglight is not free. However, you can access a free trial to get a feel for the system. Foglight runs on Windows, Linux, and Solaris operating systems.

9. Sematext Infrastructure Monitoring

Sematext Infrastructure Monitoring is a cloud-based server and services monitor that scours log records for system performance information. This tool tracks the capacity and utilization of server resources plus Java Virtual Machine and container activities.

Key Features:

• JVM Monitoring: Track issues in Java Virtual Machines
• Delivered from the Cloud: Monitors both cloud and on premises resources
• Examines Garbage Collection: Looks at memory recovery

Why do we recommend it?

Sematext Infrastructure Monitoring is a SaaS package that watches over on-premises resources and cloud assets. The system includes monitoring capabilities for JVM and containers but not for standard hypervisors, such as Hyper-V and VMware. The system is particularly concerned with memory usage and cleanup, which are important issues for the efficient operations of JVM.

As it is based in the cloud, Sematext isn’t limited to monitoring servers on just one site. You can include any server anywhere in the monitoring program. That includes cloud services. In order to bring a server into the Sematext monitoring system, you need to install an agent program on it. Once the server is enrolled, all of the services operating on it are monitored. That includes JVM instances and containers.

The container monitoring part of Sematext Infrastructure Monitoring focuses on Docker and Kubernetes. It can track the activities of each container and log its resource usage. That performance can be related to the resource usage of the supporting server.

JVM monitoring watches over Java activities and monitors its resources. This includes garbage collection activities and memory usage. Memory metrics tracked in the Sematext Infrastructure Monitoring service include heap size and usage for each memory pool. You can also use the Sematext system to adjust memory allocations, so it isn’t just a monitoring service. The system counts JVM threads and records file interactions.

The Sematext Infrastructure Monitoring service provides overviews of server and service activities that consolidate performance data. So, you start off with a collective view of server or JVM performance and then drill down to individual instances. The system gives you live performance data and lets you filter and sort performance reports for analysis. You can also call in historical data for activity analysis.

Other features in the Sematext Infrastructure Monitoring platform include transaction tracing for APIs, which track over the internet to the hosts of the services that lie behind those API interfaces. It is also able to monitor databases.

Who is it recommended for?

This service is a good choice for businesses that have resources on numerous sites and cross into cloud platforms as well. The JVM and container systems lend themselves to DevOps teams that create and manage applications for use by others. The lack of hypervisor monitoring is a problem with this tool.

You can get Sematext Infrastructure Monitoring for free by accessing the Basic package, which is limited to monitoring three servers. There are two paid plans: Standard and Pro. Each paid plan is a metered service with a rate per host per hour. You can get a 14-day free trial of Sematext Infrastructure Monitoring.

10. SolarWinds Virtualization Manager

If your VM system is a little more complicated than one server, you will probably need to step up to the SolarWinds Virtualization Manager.

Why do we recommend it?

SolarWinds Virtualization Manager provides analysis and monitoring for VMware vSphere, Hyper-V, and Nutanix virtualizations. This system discovers and maps all hypervisors on your system and adds in the new ones as they are created. It generates a dependency map that shows you what resources each is using.

The dashboard of the Virtualization Manager software shows detailed performance metrics and includes data visualization elements, such as dials and live performance line graphs. The system will show both VMWare and Hyper-V environments, keeping separate lists of the metrics on each supporting OS type if you have a mix of both systems running on your network. Alerts are color-coded: yellow indicates warnings and red highlights critical conditions. A list of potential alert situations stands ready in a separate panel of the dashboard. This utility watches out for service conditions that have reached a point of performance impairment and approach a Warning condition.

Key upgrades that this tool has over the VM Monitor include capacity planning assistance and “sprawl management“. A combination of these two tools gives you predictive recommendations. Thanks to this planning feature, you are better armed to head off overcapacity in one area of the environment and reallocate under-utilized resources in other areas of the system.

A simulation module lets you test the effects of adding more users or applications to the network. This models CPU usage, memory availability, storage capacity, and network demands for a given scenario. The sprawl feature shows you where VMs are idle and allows you to power them off and reallocate the resources assigned to them.

This is a handy feature that helps get the most out of your budget and stop you from mistaking dead processes for resource demand. At the other end of the spectrum, the sprawl monitor shows you which VMs are gobbling up all of your resources. This allows you to limit allocations to those nodes and also provides a starting point for investigations into inefficient software or system abuse.

The dashboard includes an Application Stack that simply shows layers of resources and the status conditions present on each. The stack is represented by lines of alert condition symbols for user groups, applications, databases, transactions, servers, and hosts. This enables you to quickly see where capacity issues impact application performance and quality of service.

The Perf Stack feature of the Virtualization Manager is a utility available in a number of SolarWinds infrastructure management tools. So, if you have already used a different SolarWinds product, you may be familiar with PerfStack. This is a graphical equivalent of the Application Stack. It shows live data in a line graph for each resource in the virtual environment. You select each of the graphs that interest you and drag and drop them onto a board. This enables you to create your own stack showing how peaks and troughs in demand for one resource, such as a database or the network, impact the performance of other resources, such as application response times or CPU usage.

The Virtualization Manager software contains a lot of information and the summary views come in handy to prevent you from being overwhelmed by data. You will soon become accustomed to the presentation format of the virtual machine monitoring dashboard and build your own working practices. These will see you switching between summaries and details and hopping over to planning tools to keep the virtual environment ticking over.

Who is it recommended for?

You don’t need to be running all three of the VMware, Hyper-V, and Nutanix systems to benefit from this system. Businesses that rely on virtualizations for resource efficiency need to ensure that they still have enough resources to feed into their VM structure. This package provides capacity planning and live resource usage monitoring.

SolarWinds Virtualization Manager doesn’t come cheap — prices start at $2,995. However, you can try the system out for 30 days free of charge.

11. WhatsUp Gold Virtualization Monitoring Add-on

Monitoring VM environments is complicated. You need to check on both infrastructure and software and monitor every element constantly in order to prevent performance impairment. Progress WhatsUp Gold covers all of the angles that you need to watch in order to successfully maintain virtualization.

Key Features:

• Addition to a Network Monitor: An add-on module to the core device monitoring service
• Monitors Major Virtualizations: Hyper-V and VMware
• Virtualization Mapping: Derived from an autodiscovery process

Why do we recommend it?

Progress WhatsUp Gold offers a core network performance monitor that can be extended by add-on modules. One of these extensions is the Virtualization Monitoring package. This service watches VMware and Hyper-V virtualizations, discovering and mapping each virtual system. It tracks the physical server resources that are allocated to each virtual environment.

The core WhatsUp Gold software implements network performance monitoring, keeping an eye on the devices that connect your network links together. However, there is a lot more that needs to be tracked to keep your VM system up and running. The Virtualization Monitoring add-on will cover those extra tasks.

A vital feature of the add-on is an extension of the network discovery function of WhatsUp Gold. This will apply to all VM components the processes of mapping connections and dependencies that the main package applies to network devices. The system check gives WhatsUp Gold a baseline and from that, the add-on builds a map that shows the application stack that supports each VM. You will be able to see which servers support which VMs and the status of server attributes and virtualization server software.

As your VM system proceeds into normal operations, the add-on will continue to monitor performance, looking out for potential failure in software, servers, and the network. Data collected by WhatsUp Gold is shown in real-time in the dashboard and it also gets saved as source information for analysis functions. With those planning tools you can work out whether any of your servers are overloaded and take appropriate action.

Who is it recommended for?

Progress WhatsUp Gold is an on-premises package that runs on Windows Server. Although the system offers a Cloud Monitoring add-on, you would primarily get this package to watch over your on-premises physical assets. All of the other capabilities of WhatsUp Gold, such as the Virtualization Monitor are paid add-ons.

WhatsUp Gold and the Virtualization Monitoring Add-on can be bought together with the Progress Application Performance Monitoring Add-on in the Systems Admin’s Bundle. The WhatsUp Gold Total Plus package gives you the core application together with all of its add-ons. Whichever way you choose to acquire WhatsUp Gold and the Virtualization Monitoring add-on, you can get them on a 30-day free trial before you commit to buy.

12. ESXi Embedded Host Client

VMWare produces a free environment to its ESXi systems, which is the ESXi Embedded Host Client. The client’s interface is browser-based, and so it is operating system-neutral. Also, you need to have the VMWare software installed and operating to use this monitoring tool. It won’t work with Citrix or Hyper-V systems. This utility is not feature-rich and it won’t give you the full system monitoring capabilities of the other options on this list. However, it would be suitable for small-business virtualization implementations and lab scenarios.

Key Features:

• Native Monitoring System: Supplied by VMware
• Free Tool: Included with the ESXi package
• Supports Labs: Better at tracking test systems than live virtualizations

Why do we recommend it?

ESXi Embedded Host Client is the VM monitoring solution offered by VMware for its ESXi product range. The monitor runs within the ESXi environment. It doesn’t work for vSphere systems and you can’t monitor any other virtualization brand with this tool. However, the service is free.

The tool offers an enhanced interface to your ESXi clients. You can set up new VMs through this utility and configure the hosting for each. The monitoring aspect of the tool gives you insight into host statuses. It will also list live data on events occurring in the VM environment.

Who is it recommended for?

If you are using VMware’s ESXi system, this monitoring tool is an obvious choice, not least because it is free. A monitoring tool works best when it is able to get inside the system that it is monitoring to collect data and you can’t get closer to the ESXi structure than this tool.

This is a simple tool, but the fact that it is free and that it comes directly from VMWare will tempt you to install it.

13. Turbonomic

The growth of the cloud in the provision of virtual environments can be seen by the product presentation of Turbonomic. Until recently, VM products prioritized on-site resources and then maybe dealt with Cloud-based services. In Tubonomic’s case, the tool is headlined as a utility to monitor Cloud resources. Oh, and by the way, it can also watch any onsite VM servers you might have.

Key Features:

• Monitors Cloud Systems: Tracks virtual server performance
• VM Monitoring: VMware, Hyper-V, and Nutanix
• Virtualization Mapping: Fed by a continuous discovery process

Why do we recommend it?

IBM Turbonomic is an application monitor that traces through to underlying service until it has mapped and logged all resources right down to physical assets. This drill-down path encounters all visualizations where they exist and it crawls through the virtual environment as well. The tool tracks Hyper-V, VMware, and Nutanix virtualizations.

Turbonomic doesn’t skimp on onsite VM monitoring, and the system can cope very well with hybrid implementations. This very comprehensive VM performance monitoring tool for virtual environments comes in three packages: Essentials, Advance, and Premier.

Although this monitoring software is not free, you can get a 30-day free trial of the Premier package. Pricing is based on the number of workloads that the monitor covers. The Essentials package has a limit of 750 workloads, but the other two editions have unlimited capacity. The monitor integrates controlling mechanisms and integrates AI into its action recommendation processes. You get more automation with the higher plans, but all editions include capacity planning capabilities.

Turbonomic’s straightforward monitoring module includes great visualization features like charts and graphs. The tool can interact with VMware, Hyper-V, and XenServer environments.  The setup process is automated and finishes with a system health check. This scan by the Turbonomic engine maps all of your virtual environment. It finishes its onboarding with a list of recommendations on where your system problems lie and how you should resolve them. Once that initial phase completes, Turbonomic continuously monitors the environment, producing alerts on the dashboard, backing them up with action recommendations.

You can set an action rule base in the higher editions of Turbonomic to automatically perform resolution when specific alerts arise. That automation is optional and you can launch recommended actions manually, or ignore them if you wish.

This is a good tool for departments or services that adhere to service level agreements. Those SLAs can be translated directly into the monitoring system as quality of service requirements. You can set alert levels for aspects of service including response times for delivery and transaction throughput for billing.

The monitor allows you to reallocate resources to different applications or user groups and highlights areas where an expansion of cloud resources is inevitable. On the flip side, the Turbonomic AI engine will show you where you have over-provisioned, allowing you to scale back online services and cut costs. That capacity visualization also extends to planning functions. The interface provides a capacity testing section where you can preview the effects of extensions to the user base or the inclusion of new applications and services. This is a great planning tool for bidding processing because it will enable you to plan out your extra services more effectively.

Who is it recommended for?

IBM’s presentation for Turbonomic talks extensively about cloud monitoring, cloud migration, and all other things “cloud,” so, it seems that the company is shifting this product away from monitoring on-premises systems. The tool will monitor your on-premises systems but that fact could change as the product evolves.

The dashboard for the monitor is customizable and you can allocate different views and controls to members of your team. The ability to create a user interface that does not include any controls at all gives you the option of letting clients or directors access the system without risking damage to your VM setup.

14. Acronis Cloud Manager

Acronis aims at data center implementations on the Microsoft Cloud Platform. So, if you want to use VMWare, then this product probably won’t be for you. If your virtual environment is all Hyper-V, then read on. Acronis integrates cloud-based Azure servers into your VM infrastructure seamlessly. This is a good solution if you manage data for other companies because you can identify demand down to the tenant, examine the performance of each host, and track user activity.

Key Features:

• Monitors Microsoft Virtualizations: Hyper-V and Azure
• Manage User Activity: Limit virtual resources per user
• Watch Physical Server Resources: Track memory, CPU, and disk usage

Why do we recommend it?

Acronis Cloud Manager is aimed at MSPs and SaaS providers and it links together Microsoft virtual platforms – which means Hyper-V and Azure. The service is one of a number of modules that Acronis acquired when it bought 5nine. Other units provide security monitoring and cloud migration utilities.

The dashboard of this service is highly customizable, which allows you to create different user accounts with different access rights. This is another feature that appeals to businesses that host services. You can give a limited dashboard to customers and enable them to manage their own VM allocation. Other views can be given to team members at different levels of seniority in your own group, and it lets directors and other interested parties within your company see live views of performance data. Customizable reports enhance the data-sharing features of this package.

Acronis has tailored its product so that it specifically checks all of the boxes needed by a service provider. However, if you run an in-house facility, the resource allocation monitoring features certainly won’t harm any SLA and cost-center policies that your company operates.

Who is it recommended for?

The strategy behind this product is a clever one because it constructs a “hyperconverged” system like Nutanix AHV out of Microsoft products. The merging of cloud and on-premises systems means that you can choose to move services to the cloud without disrupting user access. This has implications for application fencing, storage provision, and backup services.

The Acronis Manager is a paid service, but you can get a free trial.

VM performance monitoring tool selection

This review has given you a wide range of VM monitoring tools to choose from. Which is the best for you? Your circumstances will dictate that. Some VM monitoring tools are really system-wide infrastructure management systems that feature great virtualization functions. Other tools in the list are just small utilities that enhance your view of VM data or improve just one aspect of VM performance.

As you will glean from the statements in this report, the network monitoring industry is in transition at the moment. Ten years ago, virtualization was in its infancy and cloud services were a new trend. Both concepts now dominate networked services. It is not impossible to predict that, very soon, cloud services and the virtualization technology that makes them possible will be the standard method of network provisioning. The complexities of on-site server and application management will be a thing of the past.
