 |
|
The following Perf Counter test for CPU Utilization % (CPU 1 of 2) works fine sometimes, an at other times, in seems to get stuck in a condition where the RMA always returns "RMA: 301 - Error: A counter with a negative denominator was detected."
I've read through:
But since the RMA is running the test, trying to change HM's PerfWorkMode does not sound right. The odd thing is that same test on CPU(0) of the RMA always returns a valid value. (There are 2 processors on the RMA box)
Any thoughts?
HM: v4.16 on Win2K SP4 ---- RMA: v1.11 on Win2K SP4

"A counter with a negative denominator was detected"?
Its not a RMA message, this message was returned by some performance DLL.
Why? I don't have any idea 
Microsoft.com and Google.com did not find any information about this message. What's more interesting our Windows 2000 SP4 and Windows XP systems do not contain this message at all. Probably 2 processors system has some other DLLs related to Performance Counters...

Yes, I also googled for information on this (both web and newsgroup) and was surprised by the total lack of references.
Must be a very uncommon eror.
Question: If I use CPU test instead of Perf counter and RMA machine has multiple CPUs, am I looking at CPU(0) or CPU(Total)? |

Oh dear, I just changed it from Perf Counter test to CPU Usage test and the RMA machine is now reporting CPU Usuage at 218%
I'd sure like to know how to get that much performance out of all my processors 
To be fair, this is an older machine - one of the few we have left running NT - but it's SP6a with the latest patches. |

H'm, truth to say we never was able to test HostMonitor on NT 4.0 SP 6a. We have system with NT 4.0 SP3, and NT 4.0 SP4. But every time I installed SP 6a, system crashes when user login to the system

No big deal. I have alternate means/tests to determine if this particular host is in distress.
We've just about phased out all of our NT boxes and I am pushing to kill this one as well.
RMA is installed on ~97 host machines so far and this is the only one that seems to be giving me any real trouble. Most other issues have been traced back to me choosing the wrong test type/etc. |
