Workload balancing with TEP situations – graphical view

Workload balancing with TEP situations – How it works
GAR1 is over and GAR2 is under -> internet branch workload directed to GAR2

GAR2 is over and GAR1 is under and not CAPPED -> internet branch workload
back to GAR1

Situation is open when GAR1 CPU usage is over 99%
Both under – both not CAPPED -> internet branch workload back to GAR1
