This event is logged by EventSentry's performance monitoring feature because a group alert was triggered.
EventSentry supports Performance Monitoring Groups that allow you to add two or more already monitored counters to be added to a group and be notified when all included counters exceed their set limit at the same time.
The Alret Group can be configured at "Packages -> System Health Packages -> Package Name -> Performance Monitoring -> Alert Groups".
