Geoff - that is awesome!! Very nice presentation - and it covers all the prime touch points near and dear to the DBA at a glance. My curiosity is bristled - data cached in a local database? for how long? User-settable thresholds on all counters? User-settable sample rates? Alerts when thresholds exceeded (SQL or UI)? All hooks through WMI? Can you track other stuff like auto-grows, errors, failed authentications?

To be honest, I have yet to dabble in PS, although it seems like all the rage for scripting these days.

Again - very nice job.
