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:
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.
Operating System: Ubuntu 20.04 Application: Apache HTTP server Version: 2.4.41 IP address: 22.214.171.124 Document root: /var/www/html
Enable 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-enabled
Ensure that the
status.load files are present. If not, you need to enable mod_status module by invoking the command:
$ sudo /usr/sbin/a2enmod status
Configure 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
$ 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.
Save 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 apache2
Thereafter, browse the web server’s URL as shown.
You will get a status HTML page displaying a host of Apache’s information and an array of statistics as shown.
NOTE: 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.
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.
