"""
Nagios Plugin to check Attivio AIE system health including any nodes down, performance monitoring down,
warning and fatal error counts as well as acknowledged counts
Nodes Down and Fatal errors result in CRITICAL status
Warnings or performance monitoring down result in WARNING status
Tested on Attivio 5.1.8
