Apache by Zabbix agent
Overview
For Zabbix version: 6.2 and higher
The template to monitor Apache HTTPD by Zabbix that work without any external scripts.
Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.
Template Apache by Zabbix agent - collects metrics by polling mod_status locally with Zabbix agent:

It also uses Zabbix agent to collect Apache Linux process stats like CPU usage, memory usage and whether process is running or not.
This template was tested on:
- Apache, version 2.4.41
Setup
See Zabbix template operation for basic instructions.
Setup mod_status
Check module availability: httpd -M 2>/dev/null | grep status_module
Example configuration of Apache:
<Location "/server-status">
SetHandler server-status
Require host example.com
</Location>If you use another path, then don't forget to change {$APACHE.STATUS.PATH} macro.
Install and setup Zabbix agent.
Zabbix configuration
No specific Zabbix configuration is required.
