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.

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. * Jeremy Farrar Systems Intergrator Adapt of America * -------- Original Message -------- Subject: [Nagiosplug-help] check_nt returning bogus values Date: Thu, 10 Jan 2008 09:46:01 -0600 From: Jeremy Farrar <jer...@gm...> To: nag...@li... 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. Jeremy Farrar Systems Integrator Adapt of America 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. |
