[Nc-net-user] [Fwd: Re: [Nagiosplug-help] check_nt returning bogus values]

[Thomas Guyot-S. <de...@ae...>]

Hi,

I'm not a subscriber of nc-net-user, however I found this thread in the
Nagiosplug-help mailing list that may be of interest for you.

The author of the email may be using an old release from shatterit.com
but since it also affects Windows's own performance monitoring apps this
may apply to NC_Net 3.x and 4.x too. I hope this may be useful.

Thomas

Thanks for the reply, Mark. You pointed me in the right direction to
solve my issue. I compared the perf*.dll files on the server that was
giving me problems with the files on a server that was working. All of
the DLLs had the same version number.

I launched perfmon on both servers. I noticed that perfmon did not
display any counter data on the problem server. My research led me to
this article:

http://support.microsoft.com/kb/152513/en-us

I ran regedit and noticed that the keys located at*
HKEY_LOCAL_MACHINE\Software\Microsoft\WindowsNT\CurrentVersion\Perflib\009
*were different between the servers. I copied the keys from the good
server to the bad one. Perfmon.exe started running normally as soon as
it was relaunched. The NC_Net service started reporting accurate data
shortly thereafter.

Once again, thank you very much for the reply. I would not have been
able to figure it out without you. I hope my experiences can help
someone else in the same situation.

I am in the process of setting up a Nagios system to monitor my
datacenter. So far, I have 55 hosts in my windows hostgroup. One of the
commands that I am running against the windows host group checks for CPU
utilization on the servers using check_nt and NC_Net. Out of the 55
servers, two of them return a CPU utilization of 4294967295%. All of the
other servers run normally. I have uninstalled the NC_Net service and
manually removed the registry entries as highlighted in the
documentation that comes with the service. I still have the same error
after reinstalling. I actually receive 4294967295% as the utilization if
I run the check_nt command manually from the CLI. That leads me to
believe that the issue is with the server itself rather than Nagios. Has
anyone ran into this issue before? Any assistance would be greatly
appreciated.

P.S. I imagine this issue has come up before. I searched the archives
but I could not find anything addressing this issue. I apologize in
advance if this has been addressed before.
