What is mod_status?
mod_status is an Apache module that helps to monitor web server load and current httpd connections with an HTML interface that can be accessed via a web browser.
Apache’s mod_status shows a plain HTML page containing the information about current statistics of the webserver including.
- Total number of incoming requests
- Total number of bytes and counts server
- The CPU usage of Webserver
- Server Load
- Server Uptime
- Total Traffic
- Total number of idle workers
- PIDs with the respective clients and many more.
The default Apache Project enabled their server statistics page to the general public. To have a demo of the busy web site’s status page, visit.

How to Enable mod_status in Apache in Ubuntu?
Step - 1 - 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 | grep status*
status.conf
status.load
Step - 2 - 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 status
Step 3 - 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 status.conf file.
$ sudo vi /etc/apache2/mods-enabled/status.conf
Refer a image below
Set the Require ip directive to reflect the IP address of the machine that you will be accessing the server from.
Step 4 - Save the changes and restart Apache for the changes to take effect to confirm the status as shown:
$ sudo systemctl restart apache2
$ sudo systemctl status apache2
$ curl http://server-ip/server-status
$ curl http://server-ip/server-status?refresh=5
