Package sun.jvmstat.monitor Description

Provides classes for monitoring instrumented HotSpot Java Virtual Machines.

The classes in this package provide abstractions for:

• Identifying monitorable hosts and Java Virtual Machines.

• Monitoring the creation and destruction of instrumented Java Virtual Machines on local and remote hosts.

• Discovering and Monitoring instrumentation exported by an instrumented Java Virtual Machine.

The MonitoredHost class provides the interface to acquire concrete implementations for discovering instrumented Java Virtual Machines on a specific host. It serves a factory for creating MonitoredHost instances for specific hosts and for creating MonitoredVm instances for specific instrumented Java Virtual Machines on those hosts.

The MonitoredVm instances provide an interface for discovery of instrumentation objects and the Monitor interfaces provide a mechanism for monitoring the instrumentation exported by a JVM.
