HP OSMS Blueprint: HP Manageability Value-Add Software for Open Source Middleware Stacks

Event-Driven Methods
The event-driven methods are used to manage events that are triggered when certain conditions
are met, for example, if the JBoss Application Server process uses a greater percentage of CPU
bandwidth than the threshold defined in the policy. When a threshold is exceeded, warning
messages appear in the management console. Table 3 lists the JBoss SPI policy details.
