Class GangliaElementProducer

java.lang.Object
  org.globus.mds.usefulrp.glue.GangliaElementProducer

All Implemented Interfaces:

GLUEElementProducer

public class GangliaElementProducer

extends java.lang.Object

implements GLUEElementProducer

An instance of this class will provide an XML element for a cluster in the GLUE schema using data gathered from a ganglia gmetad that should be running elsewhere. This can then be used, for example, as a ResourceProperty value.

Field Summary

(package private) java.lang.String	gangliaClusterIdentifier Cluster to report info for.
(package private) java.lang.String	gangliaHostName hostname or IP address to connect to for Ganglia data.
(package private) int	gangliaTCPPort TCP port to connect to for Ganglia data.
private static org.apache.commons.logging.Log	logger
(package private) java.lang.String	xsltFilename Points to the XSLT file that will perform the glue to ganglia transformation.

Constructor Summary

GangliaElementProducer()
Creates an instance with all default params.

Field Detail

logger

private static final org.apache.commons.logging.Log logger

gangliaHostName

java.lang.String gangliaHostName

hostname or IP address to connect to for Ganglia data. defaults to localhost.

gangliaTCPPort

int gangliaTCPPort

TCP port to connect to for Ganglia data. defaults to port 8649

gangliaClusterIdentifier

java.lang.String gangliaClusterIdentifier

Cluster to report info for. XML from the Ganglia daemon may contain information for multiple clusters, but we want to select a specific one. For the moment, just use a cluster name -- potentially it would be necessary to match against Grid name too if Ganglia has such an attribute?

xsltFilename

java.lang.String xsltFilename

Points to the XSLT file that will perform the glue to ganglia transformation. TODO Probably should be configurable?
