I have found the following Issue when creating a report from a Custom Performance Counter that was added to a Custom Management Pack.
If you would like to follow along, First, create a new Management Pack and then under Authoring create a Rule for a performance counter ie: % Processor Time.
Second, go to Reporting and under “Microsoft Generic Report Library” open the “Performance” report and fill out all the details. When you go to selecting the counter you will see an uninterperatable name. This is displayed as a sequence of numbers and letters where the counter name should be, this is obvious from the screenshot below:
This becomes a real neusence when you get your report results as the ‘Rule:’ detail is not interperatable. So should you forget what you printed or saved, you will not be able to reference this in the feature. See the follow screenshot:
I have highlighted where you should see what the counter name is, if you were to look back at this report in the future you would not be able to tell that it was % Processor Time.
