@Lan yes, this is expected when you import the data onto a different machine ... some of the counters will be different. Look at the other articles in this series (I did an entire week on working with performance counters) where I describe some techniques you can use to remove "machine specific" information.

Hi,

When I use the import-counter to load blg, it throws a lot of errors:

Import-Counter : The data in one of the performance counter samples is not valid. View the Status property for each PerformanceCounterSample object to make sure it contains valid data.

Is that normal ?

thanks, Lan

@Klaus

In general what you do with all the information that is gathered, depends on what you find. For example, if you find that you are using too much of your physical memory, then you may decide you need to add additional memory. If your disk queue length is too high, you will need to look at adding additional drives, a better array controller, or attempting to partition the database, or move stuff around. There are some very good articles about performance tuning on TechNet that are specific to particular applications (such as SQL or Exchange) and that cover what counters to track, and which values are to high. Hope this helps.

Hey Ed,

now I think that you could in deed write some books on performance counters!

I followed your steps on my computer and I#m really astonished to see what you can do with perfmon and powershell! I encountered several errors while importing the performace data into PS and evaluating the paths like "invalid performace indicator path" and "the data of one of the performace indicator samples are invalid" ... maybe this not that unusual but still it may worth noting that.

The question now is: What can I do with all these Informations?

There's pretty much left to filter ... !
