Hi, I recently had a performance problem with one of my aggregates - it was the second time in a few months so I decided to configure Operations Manager thresholds and alarms to alert me before the IOPS reached a critical level in the future.
Its a nice post that PA is being used for diagnostic and nail down performance problems.The only commen I have is the thresholds can be created from NMC UI too. By two ways.
By right clicking on the tree map in the left hand side view.Add threshold.See attached pic one
Also by clicking on the Action butoon in the graph/chart, this give options like do a trending and baseline saying what will be a best value for threshold based on the history or the time range specifed.
