Install

Enable Apache server-status

Add this to your Apache config file:

<Location /server-status>
    SetHandler server-status
    Allow from 127.0.0.1
    Order deny,allow
    Deny from all
</Location>
ExtendedStatus On # Optional. Must be in global scope and not in a virtual host

Restart/reload Apache or use ```kill -USR1 `cat /var/run/httpd.pid ```` for zero downtime

Configure Zabbix Server

Import the template file Template_App_Apache_Status.xml into Zabbix
Link the Template_App_Apache_Status template to the hosts to be monitored

Now continue with either Zabbix Agent Mode mode or Cron mode.

Zabbix Agent Mode Install

This method relies on your polling interval for an item called apache.status, and will honor any maintenance windows. The check will run on the host being monitored everytime time apache.status is polled. This item is defined as a UserParameter like this:

# returns a single integer, but uses zabbix_sender to populate trapper items
UserParameter=apache.status,/var/lib/zabbix/bin/check_apache --config /etc/zabbix_agentd.conf

Install on apache server to be monitored and connect to status page on localhost. Assumes zabbix-agent is installed.

Copy bin/check_apache to , such as /var/lib/zabbix/bin/check_apache
Run chmod +x on the file
Copy conf/check_apache.conf to your zabbix agent include dir. Probably /etc/zabbix_agentd.conf.d/

Tip Check to make sure your include directory is enabled.

grep Include /etc/zabbix_agentd.conf

Tip Make sure you have ServerActive and Hostname filled in your config file.
Restart zabbix-agent.

Cron or Remote Mode Install

This method can run remotely or locally via cron. This method relies on your cron scheduler to set the polling interval, and is unaware of any maintenance windows.

Install on Zabbix server or the host to monitor:

Copy bin/check_apache to , such as /usr/bin/check_apache
Run chmod +x on the file
Add this to crontab to run every minute: * * * * * /usr/bin/check_apache --zabbixsource myhostname -z myzabbixserver &> /dev/null
Replace "myhostname" with the hostname (or name in the Zabbix GUI) of the host that the values should be stored with. Replace "myzqbbixserver" with the hostname/IP of your Zabbix server.

Repeat above cron lines to monitor multiple hosts. Use the -o option if these URL differs from the hostname.

Notes

Users of cPanel may need to use add the arguments " -l http://localhost/whm-server-status?auto" to prevent a "ValueError: need more than 1 value to unpack".
