DebugDiag Log Files - Can they be Deleted?

[Diane]

In looking for system drive space, I discovered several GB of
Perflog(...).blg files in the debugdiag/logs/perflogs folder and 2 old
post-mortem dump files in the debugdiag/logs/"crash rule for all iis_com+
related processes" folder. Can they be deleted ? More importantly, how are
they being generated and can I safely turn off the process? If yes, I would
appreciate directions on how to do so. This is not an area I'm familiar with
at all.

Thanks for your help and advice.

These files are safe to delete, they're Performance Monitor (Perfmon)
log files. How old are these files? This will explain how the logs are
created:

The Exctrlst tool can help with third party counters:

Thanks John. The files start at May 2007 and go forward, about 1 every month
of so. A recent one, just a few days ago. I don't see any perfmon log
defined (admin tools/performance), but I now do see that debugdiag is
installed. Perhaps from debugging session back in May?? I am wondering if I
can uninstall it to stop the creation of the logs. What do you think? I
will also try the tool you referenced, but will not get a chance to do so for
a few days. I heading out of town for travel shortly.

In DebugDiag itself there is an option to turn off or disable Perfmon
logging. In article http://support.microsoft.com/kb/919791 the
instructions read:

(Step 5): Disable Performance Monitor logging

Approximately two minutes after the user dump file capture process is
finished, disable Performance Monitor logging. To do this, follow these
steps:

1. Click Start, click Run, type the path of the Debug Diagnostics Tool,
and then click OK.

Note By default, the Debug Diagnostics Tool is located in the following
folder: C:\Program Files\IIS Resources\DebugDiag

2. On the Tools menu, click Options and Settings.
3. On the Performance Logging tab, click Disable Performance Counter
Data Logging.
