According to research from Netcraft, Apache has been the leader in the web servers market space, since 1996, one year after its initial release in 1995.
As of 2019 Apache, is it still in the top two most used web servers, only after Nginx.
Although there has been a decline in its use, Apache still holds more than half of the active sites on the Internet.
The web server is still loved because it is open-source with a great community, easy to install, and secured.
But monitoring it can be challenging when there are tons of metrics to check, infrastructure, and app dependencies.
Here is our list of the best Apache Monitoring Tools:

The five Apache Monitoring tools and software showed here can help you keep track of critical metrics such as server uptime, total traffic, busy/idle workers, user requests, CPU, memory, of your on-premises server (or cloud server).
Some tools can even help you keep up with the end-user experience.
They can help you troubleshoot and make sure that your Apache remains healthy.
Why is it Important to Monitor Apache Web servers
Keeping an Apache web server healthy is not only a matter of checking services and processes.
It is more complicated than that.
The Apache is a software package that delivers countless features, such as SSL, FTP, XML, HTTP/2, IPv6, and a lot more.
And most Apache installations run though characteristic models of web service stacks that depend on each other, like LAMP (Linux, Apache, MySQL, PHP), or XAMPP (Cross-Platform, Apache, MariaDB, PHP, and Perl).
Although Apache has always relied on on-premises infrastructure, from servers, networks, and storage, today, people also run it through the cloud.
The instances running the web server should also be monitored.
Running web server infrastructure on-premises brings another challenge to the table.
The server must be up and running, checking the CPU, memory, and other network metrics such as traffic become another daily monitoring task.
Even though Apache is highly reliable and secure, users are sometimes faced with common SSL problems, compilation, conflicted software or blocked ports, etc.
Here's the Best Apache Monitor Tools & Software of 2021:

Apache has been around for a while. And it is still serving close to half of all websites on all the Internet.
Today, Apache is a vital component of any web architecture and is the core element of the popular LAMP and XAMPP stacks.
Although it is highly reliable and secured by itself, it is always a good idea to keep end-to-end monitoring on your Apache web-server.
CPUs get overloaded, security gets hacked, or traffic gets bottle necked.
A website can go down for 1001 reasons, and it can be difficult to troubleshoot without any proper metrics analysis.
The five tools shown here can keep track of the major processes and services of the Apache server.
They can help you maintain a guaranteed uptime, improve performance, and even help you find root causes of problems.
Some of these tools can also monitor critical and often overlooked elements such as end-user experience, cloud resources, VMs, hardware and database, and more.
Fortunately, all of these powerful tools have free trials, and some of them have unlimited-time free with limited capabilities.
So there is no reason not to start monitoring your Apache web server today.
