DB Express Performance Hub: ASH Analytics and Top Activity
If you have already worked with ASH Analytics you will immediately feel comfortable with this screen. It allows
you to analyze your database's workload by combining the available dimensions. One possibility is to review a time
period on the coarse level, for example using the wait class. Upon identifying a particular wait class consuming more
resources than expected you can click on the wait class, further drilling down. Whenever you drill down a level you
can see a filter indicating what you are currently looking at. The number of statements in the lower half is also reduced
to those contributing mostly to the metric you are looking at.
