Hi and happy new year to you all!

My first conundrum of 2013... Anyone got any ideas on how I get the amount of time in any given time period that overall FCP read/write latency has been above a certain threshold? The threshold is already set in perf advisor and has been for some time.

I have the usual free opsmanager tools to hand, plus Balance.

I know there are other performance metrics I can and do look at, however for this report I have very explicitly been asked to find something that can be expressed as a percentage, and so far this is the best I can come up with (% of time in a month spent over the threshold). Any other ideas would be welcome though.

Thanks,
Peta
