Writing perfomance data to a log file

[Guest NayJo]

Hi,

 

I'm using the performance data helper library to write some performance

counters to a log file but the only format available to me seems to be the

CSV format.

 

Is there a way I can have the log written in PERFMON format?

 

////// start code

 

pdhStatus = PdhBrowseCounters(&pdhBrowseDialogConfigurationBlock);

 

if (pdhStatus == ERROR_SUCCESS || pdhStatus == PDH_DIALOG_CANCELLED)

{

DWORD dwFlags = (PDH_LOG_WRITE_ACCESS | PDH_LOG_CREATE_ALWAYS);

DWORD dwLogType = PDH_LOG_TYPE_CSV; // PDH_LOG_TYPE_PERFMON not

supported?

DWORD dwMaxSize = 0x20000000; // .5 GB?

 

// PdhOpenLog returns ERROR_SUCCESS when log type is CSV

// and PDH_NOT_IMPLEMENTED when log type is Perfmon.

 

pdhStatus = PdhOpenLog( ptcFilename, dwFlags, &dwLogType,

(HQUERY)hPDHQuery, dwMaxSize, NULL, &hPDHLog);

 

}

 

////// snip

 

Counters are properly selected and data is logged as log as I use the CSV

file format but this is not what I want to use.

 

Many thanks ahead of time.

I found out that Perfmon format files are read-only.
