I guess it should be polling gmetad. Yep -- we can create a Java socket connection to port 8649 I believe to get the XML document. So we'll need to write a Java parser for its schema if there isn't one already that we can use. Do you know of one? I looked way back in 2005 but there wasn't one back then. > - In job status monitoring it will involve jvm monitoring (that is not > related to the plugin as it just polling gmetad) correct me if i¹m > misunderstood the job concept. Job status is resource manager job status polling.

Yep it should plug into the Resource Manager AssignmentMonitor interface. Does that make sense? Cheers, Chris > >Anything you need to clarify or I have misunderstood?* > >Thank you, > >T.W.R.O.
