I'm trying to understand what you are wishing for here. If you are using data for charge-back the customer probably should not have control over what gets collected. You should want all data to be collected to do your checks and balance and provide confidence that it is complete and accurate. I would want to allow the customer to determine the granularity of the data (the intervals over which you add up things) but that's it. Processing accounting records is a very easy process. The volume of data is small and processing requirements are easy to predict. It is also very easy to audit such a process. If it has the right metrics for your charge-back, then it is hard to beat. As far as I know, Performance Toolkit files created from monitor data have only system-wide metrics and no per-user metrics. So I don't see how you would use that for charge-back. ESALPS performance history does have per-user usage summary with sufficiently high capture ratio, so you can use that for charge-back. The bonus would be that you can use some other metrics (like storage utilization) to refine your charge-back process. But it is harder to audit, and when used for charge-back it may require much stronger change control than you like for your performance management. My preference would be to implement both accounting and performance monitoring. It would allow you to validate the numbers obtained through independent processes, and the performance data helps to explain excessive usage when the customer disagrees about the charges.
