How to Monitor Apache Performance Using mod_status in Ubuntu

While you can always have a peek at Apache log files to get information about your webserver such as active connections, you can get a very detailed overview of your web server’s performance by enabling the mod_status module.
What is the mod_status module?The mod_status module is an Apache module that allows users to access highly detailed information about Apache’s performance on a plain HTML page. In fact, Apache maintains its own server status page for general public viewing.
You can view status for Apache (Ubuntu) by heading over to the address below:
- https://apache.org/server-status
The Apache mod_status makes it possible to serve a plain HTML page containing information such as:
- Server version
- Current day and time in UTC
- Server Uptime
- Server load
- Total traffic
- Total number of incoming requests
- The webserver’s CPU usage
- PIDs with the respective clients and so much more.
Let’s now shift gears and see how you can get up-to-date statistics about Apache web server.
Testing EnvironmentOperating System: Ubuntu 20.04 Application: Apache HTTP server Version: 2.4.41 IP address: 34.123.9.111 Document root: /var/www/htmlEnable mod_status in Apache Ubuntu
By default, Apache ships with the mod_status module already enabled. You can verify this by checking the mods_enabled directory by running ls command as shown:
$ ls /etc/apache2/mods-enabledCheck mod_status Module in Apache Ubuntu
Ensure that the status.conf
and status.load
files are present. If not, you need to enable mod_status module by invoking the command:
$ sudo /usr/sbin/a2enmod statusConfigure mod_status in Apache Ubuntu
As stated earlier, the mod_status is already enabled. However, additional tweaks are required for you to access the server-status page. To do so, you need to modify the status.conf
file.
$ sudo vim /etc/apache2/mods-enabled/status.conf
Set the Require ip directive to reflect the IP address of the machine that you will be accessing the server from.
Configure mod_status Module in Apache UbuntuSave the changes and restart Apache for the changes to take effect to confirm the status as shown:
$ sudo systemctl restart apache2
Then verify the status of Apache and ensure it up and running.
$ sudo systemctl status apache2Check Apache Status in Ubuntu
Thereafter, browse the web server’s URL as shown.
http://server-ip/server-status
You will get a status HTML page displaying a host of Apache’s information and an array of statistics as shown.
Monitor Apache Ubuntu PerformanceNOTE: To have the page refresh after every a given time interval, for example, 5 seconds, append the 「?refresh=5」
at the end of the URL.
http://server-ip/server-status?refresh=5
This provides a better monitoring capacity of your server’s performance than the plain static HTML page earlier on.
That’s all for now about the mod_status module. Stay Tuned to Tecmint for so much more.
