Hi Andy, I am looking at three possible ways to send data to ganglia: 1) use xrd.report and send reports to a single mpxstats. 2) use xrd.report and send report to mpxstats running on the dataserver. 3) use xrd and poll the data server from itself. I am slightly partial to #2 since it does not require a centralized receiver, and avoids any penalty associated with a login against the dataserver. Another question I have is what is the size of <int> specified in the documentation for various values (e.g oss.paths)?
