Real-time LUN IOPs
I am working with my NOC to put together storage checks we can graph out. How can we gather real-time LUN IOPs leveraging something like naviseccli (or some other CLI-based tool)? I know VNX Monitoring and Reporting can report on these metrics on a per LUN basis, but what is the command-line equivalent?
Thanks!

There have been a number of threads on this forum over the years talking about using Naviseccli commands to collect IO/s statistics on the different arrays - you might want to perform a search here to see what you find.
The Navisphere/Unisphere Command Line Interface manual would be a good place to start - the "getlun" command will list the different switches you can use to collect data - getlun is for raid group LUNs, there is a different command for LUNs that are part of a Pool.
The general idea is you collect a statistic at time point x and later at time point y and then you subtract (x-y) to get the difference between the two points and you know the interval between x and y.
