Method Detail

getAllListeners

public static List<DistributedUtils.ListenerInfo> getAllListeners(Monitor monitor)

Get a list of listeners associated with a monitor.

copyJamonBufferListenerData

public static void copyJamonBufferListenerData(Monitor from,
                                               Monitor to,
                                               int numInstances)

Copy

Parameters:

from -

to -

numInstances - Represents the total number of instances that will be sharing this buffer. This number is used to determine how many rows from each instance are put into a FIFOBuffer. The amount of rows put in each the buffer by each buffer is maxRowsInBuffer/numInstances. If maxRowsInBuffer=400 and numInstances=10 then each instance could put a max of 40 rows in the buffer. Note this number doesn't apply to other types of buffers such as max buffer where any server can dominate.

copyJamonBufferListenerData

public static void copyJamonBufferListenerData(Monitor from,
                                               Monitor to)

Copy

Parameters:

from -

to -

changeInstanceName

public static MonitorComposite changeInstanceName(String instanceName,
                                                  MonitorComposite monitorComposite)

change monitor composites instanceName as well as all of its monKey instanceNames and instance names in any JAMonBufferListener's.

Make a copy of the local monitor composite before passing to this method if you don't want to change the instance name of the 'local' monitor which you probably don't.
