javax.management.monitor.MonitorNotification
- All Implemented Interfaces:
Serializable
Provides definitions of the notifications sent by monitor MBeans.
The notification source and a set of parameters concerning the monitor MBean's state need to be specified when creating a new object of this class. The list of notifications fired by the monitor MBeans is the following:
- Common to all kind of monitors:
- The observed object is not registered in the MBean server.
- The observed attribute is not contained in the observed object.
- The type of the observed attribute is not correct.
- Any exception (except the cases described above) occurs when trying to get the value of the observed attribute.
- Common to the counter and the gauge monitors:
- The threshold high or threshold low are not of the same type as the gauge (gauge monitors).
- The threshold or the offset or the modulus are not of the same type as the counter (counter monitors).
- Counter monitors only:
- The observed attribute has reached the threshold value.
- Gauge monitors only:
- The observed attribute has exceeded the threshold high value.
- The observed attribute has exceeded the threshold low value.
- String monitors only:
- The observed attribute has matched the "string to compare" value.
- The observed attribute has differed from the "string to compare" value.
- Since:
- 1.5
