Since you might have a lot of services across your IDGs you should choose a set of services .

We can focus you on the TOP 5 (Or TOP 10) domain activity . Please remember that if you have in 2 IDG's 2 domain with the same name - They will be aggregated unless you filter by device.

Let assume you want to focus on the TOP 5 Services:

Goto Dashboards → Analytics → Service Activity .

Set Time Filter to 5 minutes (this is usually generates a 1 sec interval).

You will see your time series for each of your TOP 5 domain (Mark in Green) on the same graph on the Service Transaction (Top 5) - Marked in Red
