NGINX Plus by HTTP

Overview

This template is designed for the effortless deployment of Nginx Plus monitoring by Zabbix via HTTP and doesn't require any external scripts.

The monitoring data of the live activity is generated by the NGINX Plus API.

Requirements

Zabbix version: 7.0 and higher.

Tested versions

This template has been tested on:

  • NGINX Plus 1.19.10

Configuration

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

Setup

  1. Enable the NGINX Plus API.

Refer to the vendor documentation.

  1. Set the {$NGINX.API.ENDPOINT} such as <scheme>://<host>:<port>/<location>/.

Note that depending on the number of zones and upstreams discovery operation may be expensive. Therefore, use the following filters with these macros:

  • {$NGINX.LLD.FILTER.HTTP.ZONE.MATCHES}
  • {$NGINX.LLD.FILTER.HTTP.ZONE.NOT_MATCHES}
  • {$NGINX.LLD.FILTER.HTTP.LOCATION.ZONE.MATCHES}
  • {$NGINX.LLD.FILTER.HTTP.LOCATION.ZONE.NOT_MATCHES}
  • {$NGINX.LLD.FILTER.HTTP.UPSTREAM.MATCHES}
  • {$NGINX.LLD.FILTER.HTTP.UPSTREAM.NOT_MATCHES}
  • {$NGINX.LLD.FILTER.STREAM.ZONE.MATCHES}
  • {$NGINX.LLD.FILTER.STREAM.ZONE.NOT_MATCHES}
  • {$NGINX.LLD.FILTER.STREAM.UPSTREAM.MATCHES}
  • {$NGINX.LLD.FILTER.STREAM.UPSTREAM.NOT_MATCHES}
  • {$NGINX.LLD.FILTER.RESOLVER.MATCHES}
  • {$NGINX.LLD.FILTER.RESOLVER.NOT_MATCHES}
