Hi,
So i discovered today when deploying a new agent that there is now 4 services running for the agent.
SELinux should be either disabled or configured else the new agent fail.
Early editions of the agent would not enable the new services nor start them.
You have to go on each of them and run this :
systemctl enable --now check-mk-agent-async.service
systemctl enable --now check-mk-agent.socket
systemctl enable --now cmk-agent-ctl-daemon.service
systemctl enable --now cmk-update-agent.timer
