Host DOWN all services green

Can someone explain to me, why are all my hosts down, when I check services all are green??? And that is all the time.


Hi @Blisk

Just a suspicion: Can it be that the “DOWN” hosts, can’t be "ping"ed?
Not being able to ping a host, does not mean that you can’t reach it via tcp/6556.

HTH,

Hi
Agent and traceroute works but ping not. I thought if agent is working on host that is enough. Or I need ping too?

The host status gets collected separatedly, usually by an ICMP check.
You can change that with the ruleset “Host Check Command” where you can select “Use the status of the CheckMK agent”.
