Discovery rules“Check now”button is so weird

[Gary.W]

Zabbix 4.2.4 on Centos7

Hi everyone, I mistakenly removed all the templates in the host link today, Later I exported several important templates and restored them to the all hosts using "Mass update". Then I found that the'-->template-->Discovery rules--click "Check now"' could not be used. The feedback is "Cannot send request: host is not monitored." But I am using path following this '-->hosts-->Discovery rules 3>Check now' work's ok. Any one found this error? ps, zabbix-server.log has no relevant error messages.

I have this same question as well now.

youre pressing the button from the template level (so it doesnt work, seems from you screens ), in the last screen youre pressing it from host ( it works ) - all normal behavior


so in short template must be first assigned to host , then use check now from host
