Is there anyway to output performance logs directly to a comma separated file?

A. The Windows NT Resource Kit ships with the PerfLog service which can output data directly to a file in with comma or tab separated format. To install perform the following:

To start the service select from the Services control panel applet and click start. You can also start from the command prompt using

C:>net start "performance data log"

To change the config at a later time just rerun the PDLCNFIG.EXE image.
