Examples of QMFEvent

org.apache.qpid.qmf2.common.QmfEvent
QMF supports event management functionality. An event is a notification that is sent by an Agent to alert Console(s) of a change in some aspect of the system under management. Like QMF Data, Events may be formally defined by a Schema or not. Unlike QMF Data, Events are not manageable entities - they have no lifecycle. Events simply indicate a point in time where some interesting action occurred.
An AMQP timestamp value is associated with each QmfEvent instance. It indicates the moment in time the event occurred. This timestamp is mandatory.
A severity level may be associated with each QmfEvent instance. The following severity levels are supported:
```
 * "emerg"   - system is unusable * "alert"   - action must be taken immediately * "crit"    - the system is in a critical condition * "err"     - there is an error condition * "warning" - there is a warning condition * "notice"  - a normal but significant condition * "info"    - a purely informational message * "debug"   - messages generated to debug the application 
```
The default severity is "notice". @author Fraser Adams
