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
