Perfmon.exe CLI Options for Troubleshooting

Recently I ran perfmon.exe / from command line. It yelled at me, "Parameter is incorrect," which made me wonder what the correct one(s) might be. Well here they are! This is great for quick performance troubleshooting.

Reliability Monitor


Perfmon.exe /rel - Provides a reliability report. This can be broken down by days and weeks, with messages for events in all categories: informational, errors, and warnings. A description is included about critical system failures and even system changes like a driver installation.

Check out the cool graph it gives you!

Reliability Interactive Graph

It's also interactive. You can click on the icons to get more information about the type of events occurring at that time.


Performance Report


Perfmon.exe /report - Provides a 60 second capture of performance data and then outputs a report which can be printed, e-mailed or saved.


The report spits out a Dianostic Results page that provides a nice high-level view of what's wrong. Things like... missing drivers! (What a noob!).

Towards the bottom of the summary section there is a nice overview of the areas requiring attention.

There is also a basic resource performance average with CPU, Network, Disk and Memory utilization from the 60 second capture.


Pretty cool eh?
