Introduction:
How to set up a monitoring threshold rule to alert on bandwidth for critical above 90% for 30 minutes,, alert major, above 80% for 30 minutes, reset below these to Normal?
Environment:
Any CAPM environment
Instructions:
The best way to go about doing this is to set the threshold profiles per the documentation: https://docops.ca.com/ca-performance-management/3-5/en/building/configure-threshold-profiles.  However, to get the tiered affect you must overlap the monitoring.  For a "Major" event a breach would have to occur about 80% utilization for 30 minutes straight (i.e. 80%-100%).  The "Critical" event breach would have to occur about 90% utilization for 30 minutes staright.  When you get the critical event breach both conditions will be satisfied so you will actually get 2 events (Critical and Major).  You must do it this way because if you set the "Major" event to 80% to 89% utilization and the "Critical" event set to greater than 90% then you risk missing events if the utilization fluctuates between 80% and 90%
