Performance counters for system processes

[boerni 0]

Hi there,

 

I need to monitor some processes during the load test. I've tried to add a new WMI custom counter and used the method counter.WMIGetValue. When I use this method I will only receive one value. But I need the complete list of all processes. The main problem is the WQL query where I have to specify a column. Is there any way to get the complete record set so that I could use enumeration to get my data?

 

For example

var objWMIService = GetObject("winmgmts://<computername>/rootCIMV2");
var colItems = objWMIService.EcexQuery("Select * FROM Win32_PerfRawData_PerfProc_Process", "WQL");
var enumItems = new Enumarator(colItems);
for (; !enumItems.atEnd(); enumItems.moveNext()) {
var objItem = enumItem();
...
}

Any idea?

 

Thanks

Boerni

You can get a value for specific process using following code:

counter.WMIGetValue("Select * FROM Win32_PerfRawData_PerfProc_Process where Name = 'exampleProcessName'", "exampleParamName", 0)

Hi Sergei,

please, is somewhere any guide, that can explain how to write own performance counters?

Hi Jiri,

There is no the such guide. You can find out some information in the WAPT help and use existing counters as examples.
