Field Detail

MBEAN_TYPE

public static final java.lang.String MBEAN_TYPE

This MBean is registered using the following MBEAN_TYPE.

Method Detail

getStartLocation

public javax.management.ObjectName getStartLocation()

Returns the ObjectName representing the start location of the path being monitored. For latency monitoring, this returns the start point. For throughput monitoring, this returns the point for which throughput is being monitored.

Returns:

the ObjectName representing the start location of the path being monitored

getEndLocation

public javax.management.ObjectName getEndLocation()

Returns the ObjectName representing the end location of the path being monitored. For latency monitoring, this returns the end point. For throughput monitoring, this returns null.

Returns:

the ObjectName representing the end location of the path being monitored

getCollectInterval

public long getCollectInterval()

Gets the interval for collecting example performace data.

Returns:

the interval specified for collecting example data.

getAverageInterval

public long getAverageInterval()

Gets the interval for calculate average performance data.

Returns:

the interval specified for calculating average performance.

getThreshhold

public long getThreshhold()

Gets the threshhold set for this probe. Only these metrics that are great than the threshhold is meaningful.

Returns:

getMetric

public java.lang.Number getMetric()
                           throws javax.management.JMException

This method returns the current monitoring metric value. This will return null if no monitoring metrics have been calculated or received yet.

Returns:

Number representing the current monitoring metric value

Throws:

javax.management.JMException -

start

public void start()
           throws javax.management.JMException

This method restarts monitoring metric collection for the path after it is stopped.

Throws:

javax.management.JMException -

stop

public void stop()
          throws javax.management.JMException

This method stops monitoring metric collection for the path.

Throws:

javax.management.JMException -

ManagementException -

terminate

public void terminate()
               throws javax.management.JMException

This method terminates metric collection and unregisters this MBean from the MBeanServer.

Throws:

javax.management.JMException -

ManagementException -

isActive

public boolean isActive()

This method returns true if probe is active.

Returns:

boolean
