How does the Module filter work?
Unless you are prepared to deal with much larger Performance Sentry data files than usual, you should use appropriate filter settings when you collect Module data.

What does the Module collection function do?
A performance data Object called Module is created internally, when you include the Module Object in your Data Collection Set (DCS) data definition.

They recognized the need for capturing performance metrics on Windows NT in a fashion similar to the mainframe software called SMF (System Management Facility). Thus, Windows NT SMF […]
I do not see a drive letter for some of my logical disks. Instead, I see something that looks like HarddiskDmVolumessystemnameDg0Volume1 instead. What is that all about?
