Huh - I've never seen that before. How many systems are you monitoring? The
only thing I can think of that might do that is if you were totally overloaded
and ports were getting reused...
Anyway, glad you figured it out!

Hi Joshua
We were able to stop the problem by disabling iptables on our monitoring
server. We allow only outgoing connections and some incoming connections (like
port 80 for http).
It looks like every now and then a response from the windows server isn't seen
as response but as a new connection, resulting in a deny from iptables. We are
testing since yesterday with iptables disabled and don't have any timeouts
anymore, even without a timeout setting for check_wmi_plus.pl

I've seen that happen with one or two servers on occasion, but not
continuously. It usually has to do with either the server being overloaded or
having a problem that ultimately requires a reboot to clear. If you're seeing
it regularly on one particular server, it might well indicate a problem with
that server, not WMIC. For reference, while I was a Windows admin in a
previous lifetime, I've been almost exclusively Linux/Unix for a decade, so
this is about the extent of the WMI-related advice I can give you :)
Good luck!

Hi Joshua
I am aware of the timeout, but at the moment it is going over 60s sometime
(--timeout=60). That's too much, a lot too much....
is there any recent development in the wmic or some other solution? Problem is
this isn't aconstantly repeatble error...

I am, and yes, I had to increase the default timeouts (in my case to 45
seconds). Just add '-timeout #' to your check_wmi_plus.pl command line - you
might need to do some testing to see what the best value is for your setup.
I'm using the same version of wmic, so it does work.

Subject: [icinga-users] WMIC
Hi list
Is anyone using icinga and check_wmi_plus.pl to check windows systems?
I have a bunch of windows servers that i need to check, preferably agentless....
At the moment I use check_wmi_plus.pl but I receive a lot of timeouts on these
checks. check_wmi_plus.pl is using wmic, and the version of wmic i have is
Version 4.0.0tp4-SVN.
This client is rather old and i can't find a newer version (was part of the
Samba project, but in the newer version i don't see it anymore..)
So.. anyone who has seen these timeouts and maybe found a solution for this?
Will be difficult to get the windows admins to install a nsclient daemon....
