Probably a FAQ, but I couldn't find this in the documentation.
If I create some Windows Performance counter "monitors" for DT to collect.. Generate some load.. Store the session in "session storage".. And then create a chart on these measures from the session data..
Will the measure data get aggregated based on the age of the session data? Is it fetched from the Performance Warehouse?
Or will it retain its granularity of 10s, for ever? Is the measure "recomputed" from the session data?
I'm hoping its the latter.. So that I can compare perfmon counters from two different sessions.

Hi,
when you store your session via start recording - stop recording then you will have a 10 sec resolution in the stored session.
On the other hand if you store a session from continous session recording then there is only 1 minute resolution for data older than last 1 hour as it is fetched from the PWH.
"Recomputed" - recomputing measurements and measures is only possible for purepath based data not for monitors.
So to confirm, any measures inside a stored session do not come from the performance warehouse?
thx.. request updating the documentation with this important info.
