Check_NT CPULOAD output issue

[Matthew Hockett]

Hello,

While examining Nagios for implementation at various sites, I’ve ran into a bit of an issue. We are wanting to monitor the CPU load on various windows servers. We have the client installed and am getting information back from the check_nt –v CPULOAD command, but it seems to be dropping all trailing zero’s from the percentage. I have ran prime95 to test on a machine and can verify the processor is at 100% while the stress test is running, but my output is showing at 1% load. After some investigation I noticed that as the stress test ramps up I can watch the percentage rise, but at 10% it reads 1% and at 20% it reads 2% and so on. Any time there is a number followed by a zero, the zero is dropped from the output. This causes the load to never go into warning or critical. I was my hope that you could shed some light on this issue, or tell me that it is just a output issue and I’m not crazy ☺

Thanks!
