notications and take appropriate action. For details on developing a custom MBean and
deploying it, see Chapter 14, “Developing Custom MBeans,” in Sun GlassFish Enterprise
Server 2.1 Developer’s Guide.
The Enterprise Server provides some useful events, which you can further extend by writing
custom MBeans to emit notications. Each event can be further customized by changing its
properties.
The following event types are available:
■
Monitor events: Monitors an attribute of an MBean. Monitor events have similar
capabilities to javax.management.monitor package capabilities. In addition to monitoring
simple attributes, as Java SE 5 javax.management.monitor does, monitor events also
support monitoring complex attributes.
■
Notication events: Noties of events from a custom MBean. Use these events to write
custom events and thus extend the event dictionary. Any MBeans which can emit a
notication can be an event.
■
System events:
■
Lifecycle: Events for sever startup, showdown, and termination.
■
Log: Events triggered when the specied logger writes a log entry. For example, you
could create a management rule to send an alert to an administrator when an EJB
container logger logs a SEVERE log entry.
■
Timer: Events triggered at the specied date and time, at the specied interval, and so on.
These events have capabilities similar to the javax.management.timer package.
■
Trace: Events triggered on Entry and Exit of HTTP/IIOP request methods, EJB methods,
and Web methods. For example, you can design a servlet lter used to log interactions
with a servlet as a management rule using Web method Entry and Exit events.
■
Cluster: Events triggered when a cluster or instance starts, stops, or fails. These events
use the Group Management System cluster monitoring.
Conguring Management Rules
To congure management rules in the Admin Console:
■
In the developer prole, go to Conguration → Management Rules
■
In the cluster and enterprise proles, go to Congurations → Conguration →
Management Rules
Note – On this page, check All Rules Enabled to enable management rules globally. If
management rules are not enabled globally, none of the management rules are executed.
