In NIS 2012, you can modify Performance Monitoring to your liking, so if a particular program is running which has high CPU/IO utilization you set set a Program Exclusion to disable monitoring for that program.
There are also a few other settings as well. See below and click here for more information on the functions.
I have the same issue but I'm far from being tech savvy I have noooo clue what to do to fix this issue... it says its 96% of at least one CPU.... that does NOT sound good. Can you pleaseeee help me in as easy terms as possible lol
