Hey lgroschen.

Yes, I've been testing it yesterday, and it's working fine, you can close it.
Thank all of you for helping out

Hsmith:
It's on those hosts where active check is disabled, and that's all, i'm only using passive host check.

tgriep:
Looks like that the "active_checks_enabled = 0" did the trick , gonna do some test's today by shutting some of the hosts down.

Hi tgriep. I'm running 3.4.1, and i changed active_checks_enabled to 0, and im gonna wait and see if that would do the trick. Now that i have changed active_checks_enabled to 0, there is a red cross on every host, saying "Check of this host have been disabled" and it's true, but it there s...

Hi tmcdonald. Sorry for the late response, i have been busy with other work. i'll try to explain it better. Every client server, we have a passive nagios host check that runs every 5min, sending a passive "ok" to our nagios server. define host { use linux-server host_name bmhtest address l...

tmcdonald: I'm sorry for the confusion, this is how it looks like. Client meaning servers placed at costumers, so we clients sending a passive host-check answer to our nagios server every 5min, and that part is working fine, that i can see in the logfile af the nagios server "PASSIVE HOST CHECK...

jolson: I've changed freshness_threshold to 10 min this morning, cause i made a little mistake by setting it to 5 min and the clients are sending passive host check every 5 minutes, that could cause some false positive errors, if the server should be loaded. I'll let you know if that did the trick, ...

Jolson: I got the part about host_freshness, but i could not find any clear info about freshness_threshold, thanks for clearing that up. I've changed the host_freshness to 60, and freshness_threshold to 5. So Nagios should check every 1 minute, and the threshold should be triggert if the host check ...

nozlaf: Yes, in nagios.cfg it's set like this. check_host_freshness=1 host_freshness_check_interval=600 I also have a hosts.cfg that is a template, and i that i have. freshness_threshold 900 thinking... what is the difference between host_freshness_check_interval=600 and freshness_threshold if any, ...

hsmith:

No, nothing Stale.
It's like that the freshness is not working for some reason, cause i see "PASSIVE HOST CHECK: clientname;0;OK" every 10min, and
freshness is set to 15min, so it shouldn't register it like down.
