check_wmi plugin time-out

[ryan_terry]

I have about 250 servers in my environment. I have about 15 hosts that use the check_wmi plugin to check service status on windows hosts. Several times a week (3-5 times) the plugin says it times out for about 2 minutes, then it responds again. I have this affects all hosts using check_wmi regardless of the user account or service being checked. I have verified that on the windows side nothing is going down, but for these brief periods it seems all WMI checks fail.

Any ideas?

Here is an example log entry:

Jan 6 09:50:31 xxxxxxxxx nagios: SERVICE ALERT: XXXXXXXXXXX;Sophos AntiVirus;UNKNOWN;SOFT;1;UNKNOWN - Plugin Timed out

This is to all of those WMI checked servers? Does anything happen with your active checks to these hosts such as a Host ping check?

[ryan_terry]

Correct, all WMI checks fail, but other checks such as ping are just fine. It happens to every host that has the check_wmi plugin configured.

What level of access does your user account have that is performing these checks? Also if you are using a domain account you might need to use / instead of \, its a perl thing.

[ryan_terry]

Administrator accounts. One is a domain accoutn and one is a local account. They work 99% of the time, just have spots a few times a week where they stop. Both accounts stop at the same time, regardless if they are local accounts or domain accounts.

OK so its an intermittent issue, that normally works fine. What timeout do you presently have set for those checks? It might help to share a password\user\hostname censored service and command definition.

Is there any pattern to the timeouts? A certain day of the week or hour of the day?
