Relog is an application and as such it might be able to connect to a SQL Server. In this case, the way to connect is via ODBC driver, hence we have to create a new DSN in the computer we want to run Relog.exe, which does not have to be necessarily the same server where SQL is installed.
If we click Start and start typing ODBC it’ll show the 2 versions available in modern OS’s which are 32bit and 64bit, we need to choose the 64bit version to make it work.
Seems like being relog.exe a bit old, the only driver that actually works is the oldest, but whatever, it works!, so we choose the SQL Server 10.00.xxx one.
He also provides a bonus script at the end, which builds a dynamic pivot table of your counter information.
