FileMonitoredVm

extends AbstractMonitoredVm

java.lang.Object
↳	sun.jvmstat.perfdata.monitor.AbstractMonitoredVm
	↳	sun.jvmstat.perfdata.monitor.protocol.file.FileMonitoredVm

Class Overview

Concrete implementation of the AbstractMonitoredVm class for the file: protcol for the HotSpot PerfData monitoring implementation.

This class provides the ability to attach to the instrumentation buffer (saved or live) of a target Java Virtual Machine by providing a file URI to a file containing the instrmentation buffer data.

From interface sun.jvmstat.monitor.remote.BufferedMonitoredVm

Public Constructors

public FileMonitoredVm (VmIdentifier vmid, int interval)

Create a FileMonitoredVm instance.

Parameters

vmid	the vm identifier referring to the file
interval	sampling interval (unused in this protocol).

Throws

MonitorException

Public Methods

public void addVmListener (VmListener l)

Add a VmListener. The given listener is added to the list of VmListener objects to be notified of MonitoredVm related events. .

Note - the file: protocol currently does not support the registration or notification of listeners.

Parameters

l	the VmListener to add.

public void removeVmListener (VmListener l)

Remove a VmListener. The given listener is removed from the list of VmListener objects to be notified of MonitoredVm related events. .

Note - the file: protocol currently does not support the registration or notification of listeners.

Parameters

l	the VmListener to be removed.
