Apache by HTTP

Overview

This template is designed for the effortless deployment of Apache monitoring by Zabbix via HTTP and doesn't require any external scripts. The template Apache by HTTP - collects metrics by polling mod_status with HTTP agent remotely:

Requirements

Zabbix version: 7.0 and higher.

Tested versions

This template has been tested on:

  • Apache 2.4.41

Configuration

Zabbix should be configured according to the instructions in the Templates out of the box section.

Setup

See the setup instructions for mod_status.

Check the availability of the module with this command line: httpd -M 2>/dev/null | grep status_module

This is an example configuration of the Apache web server:

<Location "/server-status">
  SetHandler server-status
  Require host example.com
</Location>

If you use another path, then do not forget to change the {$APACHE.STATUS.PATH} macro.

Macros used

Name Description Default
{$APACHE.STATUS.PORT}

The port of the Apache status page.

 80
{$APACHE.STATUS.PATH}

The URL path.

 server-status?auto
{$APACHE.STATUS.SCHEME}

The request scheme, which may be either HTTP or HTTPS.

 http
{$APACHE.RESPONSE_TIME.MAX.WARN}

The maximum Apache response time expressed in seconds for a trigger expression.

 10
