Wow! You really did look at the code. :-)
Performance Monitor has the ability to write to counter logs to a database, so late last year I was working on adding code that would allow PAL to analyze those logs. I never finished it though because other bugs and features are taking priority over
this. I might still consider adding the feature depending on the need for it.
Keep in mind that you can always use Relog.exe (part of the operating system) to convert a binary (*.blg) log to a SQL Server table.
I am trying to avoid the need to use a SQL Server database for PAL functionality. If I took on a depenency of SQL Server, then that would make the tool more difficult to install. I still prefer a light and quick installation.
