All Implemented Interfaces:

org.globus.wsrf.ResourceProperty

public class GLUEResourceProperty

extends org.globus.wsrf.impl.ReflectionResourceProperty

An MDS ResourceProperty that will allow services to easily publish queue and host status information in the GLUE schema.
This Resource property requires cluster and queue status provider scripts to generate the actual data based on the batch system and cluster monitoring system in place.
The output of the queue status provider should be an XML document with root element a Scheduler element, as defined in the MDS usefulrp schema package.
The output of the cluster status provider should be an XML document with root element a GLUE Cluster element, as defined in the GLUE schema XML mapping.
The provider scripts will be executed approximately every 5 minutes. TODO this could become configurable, or even perhaps become non-timebased, for example, by receiving push information.
