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 software is completely free so you can start improving your website’s service without breaking the bank.

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.

1. SolarWinds Apache Monitor with Server & Application Monitor (FREE TRIAL)

The SolarWinds Apache Monitor for Server Performance with Server & Application Monitor is an application monitoring tool that can monitor Apache Web Server. The tool monitors Apache Web Server uptime, accesses, traffic, idle workers, availability, CPU load, total access, server request per second, memory, and more to identify performance issues. There is also the option to monitor other pieces of infrastructure that support the web server such as Linux, MySQL, and PHP.

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.

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

2. Paessler PRTG Network Monitor (FREE TRIAL)

Paessler PRTG Network Monitor is an infrastructure monitoring tool that has its own sensor for Apache Web Server. The HTTP Apache ModStatus PerfStats Sensor shows you a range of metrics including CPU load, server uptime, requests per second, bytes per request, number of current busy worker threads, and number of idle worker threads. The sensor shows all of this data in the form of dials which can be viewed as live and historic data.

Once the sensor has been configured the alerts system will let you know if there is an issue that requires your immediate attention. Notifications are available via email, SMS and push notifications. There is also an API that you can use to create your own custom notification scripts.

PRTG Network Monitor is free for enterprises monitoring with less than 100 sensors. If you need more you will have to purchase one of the paid versions. PRTG Network Monitor starts at a price of $1600 (£1,272) for 500 sensors and one server installation up to $10,500 (£8,352) for 5000 sensors and one server installation or $60,000 (£47,727) for 5 server installations and unlimited sensors. There is also a 30-day free trial.

3. Dynatrace 

Dynatrace is an application performance monitoring platform with Apache monitoring capabilities. The tool provides you with a performancedashboard that displays availability, 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.

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.

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.

4. ManageEngine Applications Manager 

ManageEngine Applications Manager is an application monitoring software platform that offers Apache Web Server monitoring. With ManageEngine Applications Manager you can monitor the availability, response time, CPU utilization, Bytes transferred/sec, request details of Apache Web Server, and more. The range of metrics supported by the program make sure that you know if there is anything affecting your end-users.

The alerts system included with ManageEngine Applications Manager enables the user to set up thresholds to monitor performance metrics. Alerts are sent via email and SMS so you know when a performance event takes place. Alerts are highly configurable so you can control what activities the tool notifies you about. For example, you can set a threshold for response time so that you receive alerts if the server is slow to respond.

The reports functionality in ManageEngine Applications Manager is another one of the programs strong points. Reports show historical performance data on the Apache Web Server but you can also use machine learning to anticipate future performance trends. Machine learning helps you to plan for the future.

There are three versions of ManageEngine Applications Manager available: Free, Professional, and Enterprise. The Free version supports up to five servers or applications. The Professional version starts at $945 (£751) for 25 monitors, and the Enterprise version starts at $9,595 (£7,632) for 250 monitors. There is also a 30-day free trial version.

5. AppDynamics

AppDynamics is an application performance monitoring which can automatically discover application topology including Apache Web Server. The tool can be used to provide visibility into business transactions. Data monitored by AppDynamics for Apache Web Server includes load, average response time, and errors.

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.

There are three versions of AppDynamics Application Performance Management available: APM Pro, APM Advanced, and APM Peak. APM Pro is the basic package which includes infrastructure monitoring abilities. APM Advanced also includes visibility into the application stack. Finally, APM Peak offers real-time business performance monitoring, business journeys, and transaction analytics. You can start the 15-day free trial.

6. Anturis

Anturis is an application monitoring platform that has its own Apache monitoring tool. The Apache monitor collects metrics such as the number of busy workers, number of idle workers, requests per second, Kbytes served per second, Kbytes per request, CPU usage, and memory consumption.

The tool also monitors traffic data too (which is useful for detecting common types of cyberattacks like DDOS attacks). These metrics include the number of requests per second, number of bytes served per second, and the average number of bytes per request.

In terms of configuration, Anturis uses both agent-based monitoring and agentless monitoring. You can access the program through a web-based GUI. In the event that you miss any important information here, the program has email alerts to keep you posted about performance issues.

Anturis is available as a free and paid version. The Free version supports up to 5 monitors with email alerts. Paid versions of Anturis start at $10 (£7.95) a month for 10 monitors up to $95 (£75) a month for 100 monitors. You can download the 30-day free trial or check out the pricing here.
