Altisys App Aggregation performance is Unacceptable across the week.
Drill in.
NRTT by Application

Two high-volume Altisys applications show Unacceptable performance.
One low-volume Altisys application shows Poor performance.
Drill in.
NRTT, One App, by Region

When drilled in to a single application, you see Apdex by Network Type.
This shows similarly Unacceptable application performance by region.
