Performance Counter : wrong value for virtual bytes counter

jbarrellon · Post by **jbarrellon** » Wed Nov 25, 2015 4:58 am

Hello

We're using the test Performance Counter to monitor memory used by databases (with virtual bytes counter).
However, we realized that the value returned by RMA is limited to 4GB, even if the actual value is upper.
When clicking on "Get Current Value", we also get the 4GB value.

example :

actual value on server :

Here are the test detail :

Method = PerfCounter

RMAgent = VENTE_PRIVEE-LYON_1.LY1-LM64-PROD

We tested HostMonitor on several systems and cannot reproduce the problem.
Is this issue related to HostMonitor-PassiveRMA only? ActiveRMA? HostMonitor itself as well?
What about \Process(_Total)\Virtual Bytes counter? Same problem?

Hi Alex,

We have the issue with passive RMA (we only use passive RMA).
The test is working fine with counter \Process(_Total)\Virtual Bytes.
It's also working when performed from HostMonitor.
I also tried with other process consuming more than 4GB memory and it's not working.

Also, i just realized that it's actually not working only when performed on the local server (server hosting RMA). For example, if i edit the test properties and i change only the RMA to select one installed on another server (in the same LAN), the test is now working.
I hope this is clear enough.

Thanks for your help.
Regards,
Julien

I would suggest use WMI test method instead
Select VirtualSize from Win32_Process where Caption=' oracle.exe'

for your information :

It's working with
\\localhost\Process(oracle#1)\virtual bytes
rather than
\\LY1-LM64-PROD\Process(oracle#1)\virtual bytes
(where LY1-LM64-PROD is hostname)
