javax.management.monitor.Monitor
javax.management.monitor.StringMonitor
Defines a monitor MBean designed to observe the values of a string attribute.
A string monitor sends notifications as follows:
match notification is sent.
The notify match flag must be set to true.
differ notification is sent.
The notify differ flag must be set to true.
