Re: [Netsaintplug-help] Re: NSClient Error: PDH.dll Collect CPU (karima)

[Tom DE B. <tde...@gc...>]

Same problem here on some servers. Very annoying. And for what it's
worth: it only happens on Compaq servers here (all of them are
multipocessor boxes, mostly quad CPU). 

This problem is tied together with the known issue that performance
data on NT 4.0 servers sometimes reports negative CPU values. Another
undocumented feature... As I use NSClient to graph CPU usage with
MRTG, I can tell from the graphs when some box is having this problem
again. And indeed, rebooting sometimes helps.
