I’ve been having a weird problem with my check_uptime setup for all my CentOS hosts.
The check executes fine, but in the IcingaWeb2 interface, it reports that the check has failed/faulted, however the uptime is Days or Hours or Weeks.
When I execute the command directly on the host, it returns and OK. But on the the Icinga2 agent it returns a CRITICAL.
Does anyone else experience this?
Ubuntu and Debian hosts are fine. And work as expected.
