What is Apache Web Server?

Apache Web Server is an open-source web server managed by the Apache Software Foundation. A web server is a service that sits between a server and a client device. Apache Web Server runs as a piece of software on a server and takes client requests from a user’s web browser. It then sends a response to the request in the form of a webpage. What makes Apache Web Server popular is the range of modules it offers enterprises additional features.

Modules enable customization in the form of additional features. For example, IPv6, FTP, HTTP/2, bandwidth throttling, WebDAV, load balancing, and URL rewriting are just some of the extra features that Apache Web Server has to offer. These features grant you greater control over the experience you provide to the end-user.

To use Apache all you need to do is download the software from the official website. The server software is completely free so you can start improving your website’s service without breaking the bank.

Why is it Important to Monitor Apache Web servers?

Apache Web server is an essential service. It is important to monitor all of your IT infrastructure to ensure that it continues to perform effectively – that applies equally to your Web server.

A Web server is subject to a number of potential hazards. It can become overloaded with too many connection requests. Even without the problem of dealing with the intentional overloading of a DDoS attack, a genuine surge in interest in one of your websites could use up all of the capacity of the Apache Web server.

You also have to pay attention to the host resources that are available to the Web server. Just like any application, Apache Web server needs a certain amount of CPU capacity in order to run. If it is sharing a server with other applications, those processing resources might run short. The same problem can occur with memory and disk space availability.

Monitoring all of these factors usually gives you time to head off problems. Normally, capacity issues don’t hit in an instant – they build. You should select a Web server monitor that includes performance thresholds and set those levels below full capacity for each resource – say at 70 percent of utilization. These thresholds should trigger alerts if they are crossed. That warning gives you enough time to make more resources available to your Web server and prevent it from stalling.

The best Apache Web Server monitoring tools

If you’re currently using Apache Web Server, using a server monitoring tool is vital to providing an excellent experience. Part of the battle of monitoring web servers is having the necessary tools and visibility to address performance concerns.

All of the tools mentioned in this article are excellent choices for overseeing the performance of Apache Web Server.

Why do we recommend it?

The SolarWinds Server & Application Monitor implements Apaches Web server monitoring in conjunction with simultaneous tracking of all of your other applications and services. The monitor watches the resource availability of the servers that support all of these systems. This combined monitoring capability gives the tool the opportunity to calculate resource demand and predict shortages.

Outside of Apache, the tool offers automatic application and server discovery. Autodiscovery is useful for keeping your network environment updated to make sure that you have complete visibility over what is going on.

The alerts system also offers a high level of support for Apache Web Server monitoring. The alerts system works on a threshold basis and sends alerts if a device or application matches certain performance issues. For example, if the server goes down or the CPU load reaches a problematic level the program will alert you.

Who is it recommended for?

This service is aimed at large enterprises. Small businesses won’t need the capacity of the SolarWinds monitoring systems. For full-stack performance monitoring, you could combine this package with the SolarWinmds Network Performance Monitor. The alerting mechanism in both packages provides immediate root cause analysis when your Apache Web server faces problems.

SolarWinds Server & Application Monitor starts at a price of $2,995 (£2,382). You can download the 30-day free trial.

This package monitors all of the services that lie between your user-facing system and the servers that host everything. The system is able to calculate resource demand and identify potential shortages.

Apache cannot work properly if the host is overloaded, so the Apache monitoring system of Datadog also gives you feedback on the performance statuses of the physical server as well. All of the information that the Datadog monitor collects is too much to fit on one screen, so you have the option to customize the dashboard, giving you all of the data that interests you most all in one place.

To get more information on summary displays, you just click on that element in the screen to access a more detailed data view. The Apache monitor of Datadog collects more than 180 different metrics. All of that information is more than any one person can cope with. However, the system sets performance thresholds, so you will be drawn to pertinent information when a particular status becomes a problem.

The APM gives a very deep insight into the performance of Apache. However, to get better information about the server and network performance of your operation, you will need to add on Datadog Infrastructure. A Network Performance module will show you traffic flows and help you improve performance with traffic shaping. A Synthetic Modelling module lets you have a constant check on uptime. It also gives you the capability to run your own tests on elements in your website from external agents that are located around the globe.

Who is it recommended for?

As it is a cloud-based system. The Datadog package will probably be your first choice if you don’t want to run monitoring software on your own servers – although there are other cloud options on this list.

Sematext Infrastructure Monitoring provides performance tracking for systems that lie between user-facing systems and servers. The Apache Web server is part of that remit and it will show the demand of your Web server and its throughput. You can identify peaks and troughs in demand and see how the server copes with them.

You still get network and physical server monitoring when you activate the Apache Web Server integration in Sematext. This enables you to tie together issues such as demand on the Web server and availability of resources. You will be able to link together the performance of Apache with network activity and network device availability. This provides instant root cause analysis if Apache’s performance drops.

The Sematext system includes a rule base of triggers that will generate alerts if they are activated. These send notifications to you by email, Slack message, or Webhooks. This means that you don’t have to sit and watch the console for Sematext waiting for problems because you will be drawn back to the system if your attention is needed.

Who is it recommended for?

This system is a SaaS package and it has a free edition, called Basic, which will monitor five hosts. This could be enough for small businesses. However, to get more capacity, you need to pay. There are two paid plans and both are charged per host.

You need to subscribe to the Sematext Infrastructure Monitoring service in order to get the Apache Web Server integration. Both systems are f free for use on five hosts as long as you select a short data retention period. This package is available as a SaaS package but you can also run it on your own server as a virtual appliance over Docker. Sematext offers the Infrastructure Monitoring package and the Apache Web Server integration for a 14-day free trial.

7. Dynatrace

Dynatrace is an application performance monitoring platform with Apache monitoring capabilities. The tool provides you with a performance dashboard that displays availability, incoming requests, response sizes, busy workers, application version, configuration path, infrastructure changes, and restarts. For example, you can view an Apache Web Server availability graph that shows you when the service last went offline.

Key Features:

• Cloud-based service: This is a SaaS platform
• Logs Apache configuration: Application version, configuration path, and infrastructure changes
• Activity monitoring: Availability, number of requests, idle threads, error rates, and response times

Why do we recommend it?

Dynatrace applies AI-based demand predictions to application and infrastructure monitoring and it has a particular capability for cloud monitoring. Its Apache Web server monitoring capabilities identify the activities of all the other software running on the same server and predict potential conflict of resources shortages.

A feature called deep process monitoring allows you to take a microscope to the response time of Apache services running within various processes. For instance, you can view a graph that breaks down what services are taking the most time to execute. Services include Apache modules, Database activity, PHP compilation, and PHP execution.

One reason why Dynatrace is a top tool for monitoring Apache Web Server is its anomaly detection engine. The anomaly detection engine automatically detects performance anomalies to identify concerning activity. If an anomaly is detected you will be notified by an alert. The alert will not only highlight that there is a problem but pinpoint the root cause so that you can address it early on.

Who is it recommended for?

Dynatrace offers four plans on its cloud platform and to get Apache Web server monitoring, you would need to go for the Infrastructure plan or the Full-stack Monitoring package. The latter includes the services of the Infrastructure plan. Dynatrace offers a respectable service with live activity statistics and predictive alerts.

For top-down visibility through Apache Web Server down to the process level, Dynatrace is an exceptional choice. However, if you want to know the pricing options available for Dynatrace you’ll have to contact the company directly. You can download the 15-day free trial.

Fortunately, the lowest of these includes the Apache Web server monitoring capabilities. Get the higher plans to add on application dependency mapping. This is a cloud-based service.

Alerts in AppDynamicsindependently calculate baseline values for KPIs to distinguish poor performance. The calculations are accurate enough to eliminate false positives so you don’t get sent irrelevant or incorrect alarms. From an administrative perspective, this makes sure that you only respond to important alerts.

Who is it recommended for?

AppDynamics takes a different view to performance predictions by watching data flows between applications. That unique approach isn’t really available to those who get the lower plan, which focuses on middleware and server resources. You also need to hop up one rung in the plan levels to get database monitoring.

• Too much for small businesses: Provides the greatest benefits for large and complex systems

There are three versions of AppDynamics Application Performance Management available: APM Pro, APM Advanced, and APM Peak. APM Pro is the basic package that includes infrastructure monitoring abilities. APM Advanced also includes visibility into the application stack.
