Unsupported item key in Zabbix discovery

Question

I am using zabbix 4.0. Trying to make discovery with simple check. When i click "check now", i get Unsupported item key warning. Below you can find my discovery configuration. I couldnt solve why does it give this error. Everything seems fine.

Answer 1

It fails because you have set a Simple Check type, then typed in a ssh.run... key.

SSH checks type must be configured as SSH Agent, which also enables the executed script box: this command must return a json formatted according to the LLD format.
