Obviously, you need metrics to monitor the metrics. But more seriously, I've attacked this kind of problem in the past by agreeing on a common set of first-look metrics. What is a one page set of data you start with when trying to identify a problem in a given system/subsystem. After than, other metrics must exist to solve or monitor a specific issue, or be in reusable shared sub-reports with some stated overview. After than, you can think about automatic deletion after a specific timeframe if they're in sandboxes and not connected to some documented useful purpose.
