Turned OFF Hosts (PCs) still throw Error: CRIT '[agent] Communication failed: [Errno 113] No route to host'

Hi, Thanks

‘Check period for passive Check_MK services’ has no effect
‘Check period for active services’ has an effect.

Anyway, the problem with both rules is, that I cannot fix a time period. I don’t know when the hosts will go down. And it should also be possible that hosts are down for some time, even days, what shouldn’t trigger any alerts.

I checked and it seems Rules ‘Check Host command’ has an effect, but rule ‘Status of the Check_MK services’ not. It seems, I cannot set an timeout where no alerts a trigered.
Even rule ‘Agent TCP connect timeout’ set to f.ex. 86400 s does not have an effect as after some minutes I got the messages again:

CRIT Message
[agent] Communication failed: [Errno 113] No route to host, Got no information from host, execution time 3.1 sec

Thanks so far
