In general, I don't find that the POQ tracing facility alone provides much value. It does do a great job at bloating the log, as you all notice! If you use WINDOWS_TRACING_FLAGS and set that to 10000 instead all of the facilities should get enabled.

I have an internal parser that I use. There are probably some good ones online though.

For log verbosity, no, the way its set by default is the least detailed the log gets.

Rahul, as to your point. I was actually thinking about doing a weekly series starting after the holidays that centers around one of the issues that we see during the week and how we use the log to troubleshoot them. Maybe that will help, aside from that though, I will think of a way to get some general troubleshooting guidelines set up in a future post.

Nice tip. Is there a way to reduce the log verbosity of CBS.log? like Windows Installer allows through Group Policy? I find these logs taking a great deal of space and I can't troubleshoot them anyways.

Added the way you add this Susan, let me know if that makes sense. I'll make sure Ned knows his head envy is definately justified now <G>

Blonde ?

Exactly where/how do you put this? Command prompt? Registry? As this is the only bingle hit for this so I'm not sure exactly how/where that system environment variable goes to trigger this?

(and btw don't let Ned's head envy get you down, we love your head)
