Data Logging Service is a Windows NT service that lets you log performance monitor data and alerts automatically as an unattended service. This is especially useful for logging data on a network of remote computers. The logs remain on the remote computer until you review them in Performance Monitor.
Two utilities are needed to set up Data Logging Service: Datalog.exe, the service executable, and Monitor.exe, which configures the settings file. These are included on the Windows NT Resource Kit 4.0 CD in \PerfTool\MeasTool. Instructions for using the utilities are in Rktools.hlp.
