[Zabbix 7.4.3] Network Discovery: Discovery doesn't get executed (at all)

[killom]

Hello there,

somehow Zabbix wont start my discovery:


Rule is activated.
Zabbix Server also has plenty of workers ready:

There are no errors indicating problems with discovery in zabbix_server.log

What am I missing / doing wrong?

[killom]

So I mistakenly entered an security context for SNMP check - that caused the issue. The Discovery was running - but it yielded no hosts.

There should be some way to audit a discovery. In Webfrontend you are basically running them blind. No info about if and when they are running, and what results / errors they get.

I had to enable debug logging to be able to get a hint from what might be going wrong here ...
