Guide to the OLS Dashboard

Is there a user guide/docs for the OLS dashboard?

In particular, I'm keen to understand precisely what the "Requests in Processing" metric means.

Many thanks.


Requests in Processing is the number of concurrent requests being processing at the time when the report is generated.
Thanks for the reply. When my server gets busy, I see something like 250-450 requests per sec. But "In Processing" is steadfastly 0. Surely, at least some of the time, that number should be higher?

This is watching with the RealTime option on the dashboard...
