I just setup metering to monitor two pieces of software. I noticed that at the bottom of the Usage Detail - Current Month through Today . Do the counters get reset at the end of every month? I noticed in the METER_COUNTER table there is a WINDOW_BEGIN field with 2/1/2013. I'm guessing it would be best to run a report on this at the end of every month if so. I had to ask.... either that or wait a month.
We are still using 5.3.
On the metering tab change the drop down on the right from 1 month to 12 months (or whatever your choice would be) and then click on the process name. If you select 12 months and open up one, at the bottom it gives you 12 months of info.
