Public Constructors
public MonitoredHostProvider (HostIdentifier hostId)
Create a MonitoredHostProvider instance using the given HostIdentifier.
Parameters
| hostId | the host identifier for this MonitoredHost |
|---|
Throws
| MonitorException | Thrown on any error encountered while communicating with the remote host. |
|---|
Public Methods
public Set<Integer> activeVms ()
Return the current set of active Java Virtual Machines for this
MonitoredHost. The returned Set contains Integer instances
holding the local virtual machine identifier, or lvmid
for each instrumented Java Virtual Machine currently available.
Returns
- Set - the current set of active Java Virtual Machines associated with this MonitoredHost, or the empty set of none.
Throws
| MonitorException |
|---|
public void addHostListener (HostListener listener)
Add a HostListener. The given listener is added to the list of HostListener objects to be notified of MonitoredHost related events.
Parameters
| listener | the HostListener to add. |
|---|
public void detach (MonitoredVm vm)
Detach from the indicated MonitoredVm.
Parameters
| vm | the monitored Java Virtual Machine. |
|---|
Throws
| MonitorException |
|---|
public MonitoredVm getMonitoredVm (VmIdentifier vmid)
Get the MonitoredVm for the given Java Virtual Machine. The default sampling interval is used for the MonitoredVm instance.
Parameters
| vmid | the VmIdentifier specifying the target Java Virtual Machine. |
|---|
Returns
- MonitoredVm - the MonitoredVm instance for the target Java Virtual Machine.
Throws
| MonitorException |
|---|
public MonitoredVm getMonitoredVm (VmIdentifier vmid, int interval)
Get the MonitoredVm for the given Java Virtual Machine. The sampling interval is set to the given interval.
Parameters
