public JmxMonitor()

Method Detail

addJmxMonitorListener

public void addJmxMonitorListener(JmxMonitorListener listener)

Registers custom JmxMonitorListener

Parameters:

listener - - listener to receive metrics for formatting

notifyListeners

public void notifyListeners(long uptime,
                            ServiceMetrics[] metrics)

Passes metrics to all registered JmxMonitorListener objects

Parameters:

uptime - - time when the metrics were collected

metrics - - current metrics

isVerbose

public boolean isVerbose()

setVerbose

public void setVerbose()

getMaxServiceNameLength

public int getMaxServiceNameLength()

initialize

public void initialize(String remoteServerURI,
                       long samplingInterval)
                throws Exception

Connects to a remote JMX server identified by given remoteServerURI. Creates proxies for all UIMA AS ServicePerformance MBeans found in the JMX server registry. If UIMA AS service MBean indicates a remote service, this method connects to a remote Broker and creates a proxy to an input queue for that service.

Parameters:

remoteServerURI -

samplingInterval -

Throws:

Exception

getServiceCount

protected int getServiceCount()

collectStats

protected ServiceMetrics[] collectStats(boolean initial,
                                        long uptime)

run

public void run()

Retrieves metrics from UIMA-AS MBeans at defined interval.

Specified by:

run in interface Runnable

isRunning

public boolean isRunning()

doStop

public void doStop()

main

public static void main(String[] args)
                 throws Exception

Throws:

Exception
