Description

I want to add a 'Zabbix Trigger' Monitor, which will query the API of a Zabbix Server and get the status of a trigger.

Resolves #1960

Why? I use uptime-kuma as a simple 'customer-side' status page. In the background there is more complex monitoring using Zabbix.
It would be nice to use the existing data & triggers from zabbix and show them in uptime-kuma, to get the true overview into the status page and not only part of the monitoring.

If I understand it correctly, you meant this monitor will query the Zabbix API in a fixed interval like another monitors do.

If yes, it is OK to be added.

You can add a new monitor type here: https://github.com/louislam/uptime-kuma/tree/master/server/monitor-types

Here is the tailscale monitor for your reference: https://github.com/louislam/uptime-kuma/pull/3178

I am still working on 2.0.0, this pr may be expected in 2.2.0.

Let me know if assistance is needed, this would be incredible for me as I use Zabbix for our admins, and uptime kuma for our customers status pages.

Hi, thanks for your Feedback. I already started trying out a implementation, so it shouldn't take long to finish it.

If I understand it correctly, you meant this monitor will query the Zabbix API in a fixed interval like another monitors do.

Exactly.
