I just tried a yum remove of app-network-detail-report and it did not remove pmacct nor bring down my system-mysqld cpu usage, even after a reboot. But a yum remove of pmacct did remove both and did clear up my cpu usage even prior to a reboot. I am now back to the approximate 1% average cpu usage I used to have versus 100-200% (2 of my 4 cpu cores!) with all this reporting stuff running. Suggest these modules be seriously refactored.
