All Implemented Interfaces:

org.globus.wsrf.ResourceProperty

public class AccumulatorResourceProperty

extends org.globus.wsrf.impl.ReflectionResourceProperty

An MDS ResourceProperty that will allow services to easily publish metrics about their load.
This RP is specfically designed for measuring cumulative quantities (such as number of hits, number of bytes transferred), with the TODO ability to publish derived statistics such as average rate of change of the accumulator (which will provide, for example, hits/second or bytes/second).
Note that this RP implements no persistence (in order to have minimal dependencies on other configuration) but will TODO indicate in its output when it began making the present set of measurements.
