Nagios Support Forum

PS: I hope I have no written too many crap :oops: No problem. Interesting issues you bring up. You may want to upgrade to 3.5.1 as there were a number of bug fixes. 4.0 brings much better performance, but it is still a rather young release. Would some of those bug fixes in 3.5.1 address host and se...

I also have my max_host_check_spread set at =30 as well.

I should be able to adjust both of these down to 5-10 minutes and help my problem out.

Just curious, I notice my max_service_check_spread is =30.

1. Depending on the server, approximately 5000-6000 hosts with one service check each. 2. All date/time/timezone are correct on the servers 3. When I restart, I see all "next_check" scheduled from between the moment of restart to no later than 20 minutes out. Which, if I restart every 10-2...

Even if we slow down to every 60 minutes, with checks every 5 minutes, we have hosts that aren't being rechecked in that 60 minutes. Eric Feld...

It's not that the nagios process or host checks are hanging up, it's that they start over from the top of the host files when the nagios service is reloaded/restarted and so newer hosts added at the bottom don't get checked at all or very intermittently.

I have several Nagios 3.2.3 servers that monitor dynamically changing networks, i.e. new hosts, old hosts disappearing, etc.., where a script dynamically generates a file with hosts and then restarts the nagios service. What we're finding is if we restart the nagios service too often, the host check...
