Class/(Cluster)	Description
ASSERTION	Represents a single type of important predicate that the system should validate. Assertion failures result in everything from messages or statistics being logged to system failure.
EVENT	Represents a single event to be recorded (or that has been recorded) in the event-log. The event includes a source, description, importance, and time, among other things.
LEVEL	Represents the importance level of a particular event.
LOG	Manages the storage and retrieval of events that are reported by various parts of the system framework and/or the application built on top of it.
MESSAGE	Represents a single textual message that needs to be displayed or recorded.
STATISTIC	This class represents a statistic that can be monitored in the monitoring system. Each statistic has its own unique ID (node-unique, not necessarily globally unique), a description, units, and other useful information that is represented in this class.
TYPE	Represents the type of a particular event. The set of core event types each have such a name and a description.
