sudo systemctl show -p SubState --value wazuh-agent
Oh I see what you have going on (a bit tired cranky kid last night).
From the top
Active: active (running)means the service is setup to start on boot and is running.Active: failedmeans the service crashed for some reason. Check journalctl for more detailsActive: inactive (dead)means not set to start on boot, and not running. -
Also you could setup your monitoring to report/alert for "Anything but
active (running)". It would have the same effect, because in any case of the services not running this system function stops working. -
Did you go through the
systemctl enable wazuh-agentso the service is started at boot? -
There are also other SUB status as show here

I get this when I check app armor status via
apparmor_status

I tried using

@IRJ Did you look at journalctl to see what the logs say?

He doesn't care about why things are failed. He just wants the states. It is for monitoring and automation.
