SOLVED: Zabbix "Agentless" SSL Certificate Monitoring

[flakrat12]

Howdy, I figured I'd share my notes setting up SSL certificate monitoring within Zabbix. This can be done without installing an agent on the remote sites/web servers by using a Zabbix Agent 2 (package `zabbix-agent2`) running on another system (including the Zabbix server) to act as a proxy.

We are running Zabbix 7.2.

Example, monitor the certificate on https://zabbix.com

• Create a new host zabbix.com
• Add to hostgroup: SSL Servers
• Assign template: Website certificate by Zabbix agent 2
• Interface: 127.0.0.1 Port: 10050
• Click Macros and Inherited and host macros
  • Edit the value for {$CERT.WEBSITE.HOSTNAME} to zabbix.com
• Repeat to add more sites...

zabbix_get -s localhost -k web.certificate.get\[zabbix.com]

For clarity: In {$CERT.WEBSITE.HOSTNAME} replace <Put DNS name> with zabbix.com
