In NFA currently for alerts we can set a
threshold for TOS 0 for some number of minutes, but it looks at every minute,
if I set 30 minutes and 80%, it will only alert if it is over 80% for every
minute, if it goes below for 1 minute of the 30 it will not generate an alert.
We need a way to alert if the usage is over the threshold for most of the minutes in 30 minutes, or if it is over threshold for 15 out of the 30 minutes.
Some kind of windowing like we can do in CAPC or NV
