SharePoint Dragons

When doing performance analysis, we routinely record .blg files using perfmon to inspect the various servers involved in the SharePoint farm. We were looking for a library or piece of .NET code to read such .blg files but eventually came to the conclusion that there are only two workable solutions:

• Use the Relog tool (http://technet.microsoft.com/en-us/library/bb490958.aspx), which we found out is the approach used by MS Field Engineers.
• Use the PowerShell Import-Counter command  http://technet.microsoft.com/en-us/library/dd367896.aspx , like so:

$result = import-counter .\sample.blg
$result | export-counter -path .\output.csv -FileFormat csv
