I am looking to create a report that takes specific IPSLA operations and based on a 300ms "Critical" threshold counts how many times this operation exceeded that threshold in a given month. I will then figure out a percentage based on that number outside of our threshold. As a bonus if you can subtract the number of critical events from 8640 and then divide that number by 8640 and multiplied by 100. That should give me a straight percentage. See below example. If anyone has any ideas on how to accomplish this it would be greatly appreciated. Thank you.
Site SLA - Critical count 120
8640 - 120 = 8520
8520/8640 = 0.9861
0.9861 x 100 = 98.61%
