CMK version:
2.1.0p9
OS version:
Debian 10
In some cases when I install the agent it generates a failed systemd service (cmk-agent-ctl-daemon) I really don’t know why this fails, on many other servers it works fine, even though this service seems to fail the agent does report as usual.
Does anyone know what might causes this?
Hi @fisher,
what does the service itself tells about the fail? Have you checked the output of systemctl status cmk-agent-ctl-daemon.service or journalctl -u cmk-agent-ctl-daemon.service?
hey @tosch ,
systemctl status cmk-agent-ctl-daemon.service output is

There is something already listening on the port.
