com.sun.appserv.management.event.StatisticMonitorNotification
Provides definitions of the notifications sent by statistic monitor MBeans. Used for JDK version greater than 1.5.
The notification source and a set of parameters concerning the statistic monitor MBean's state need to be specified when creating a new object of this class. The list of notifications fired by the statistic 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 statistic 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 statistic monitors).
- CounterStatistic monitors only:
  - The observed attribute has reached the threshold value.
- GaugeStatistic monitors only:
  - The observed attribute has exceeded the threshold high value.
  - The observed attribute has exceeded the threshold low value.
- StringStatistic monitors only:
  - The observed attribute has matched the "string to compare" value.
  - The observed attribute has differed from the "string to compare" value.
