Is there a way to monitor the TDEV IOPS(realtime and history) in Unisphere for VMAX GUI? My storage is VMAX 10K.
history yes, under performance you can drill down to look at individual devices. It's still only on 5 min poll so you get an average value. You can play with real time trace but i don't remember if it's as granular as what you are looking for.
I notice you are still at Unisphere 1.6 which is EOSL for a number of years now, is there a reason why you haven't upgraded?
there is a new real time feature offering 30 second granularity available in the new unisphere 9.0 but you require to be at 5978 code on the array. you can see more about it here
