Website certificate by Zabbix agent 2

Overview

The template to monitor TLS/SSL certificate on the website by Zabbix agent 2 that works without any external scripts. Zabbix agent 2 with the WebCertificate plugin requests certificate using the web.certificate.get key and returns JSON with certificate attributes.

Requirements

Zabbix version: 7.0 and higher.

Tested versions

This template has been tested on:

Website TLS/SSL certificate

Configuration

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

Setup

1. Setup and configure zabbix-agent2 with the WebCertificate plugin.

2. Test availability: zabbix_get -s <zabbix_agent_addr> -k web.certificate.get[<website_DNS_name>]

3. Create a host for the TLS/SSL certificate with Zabbix agent interface.

4. Link the template to the host.

5. Customize the value of {$CERT.WEBSITE.HOSTNAME} macro.

Macros used
