Subject [jira] [Commented] (OODT-618) Implement ganglia XML parser
Date Wed, 12 Jun 2013 20:12:20 GMT

    [ https://issues.apache.org/jira/browse/OODT-618?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13681578#comment-13681578

Chris A. Mattmann commented on OODT-618:

Hey Rajith, 

bq. there is nothing to be added to the XMLUtils from parser. but as DOM parser we can add
getting SAX parser instance like methods to XMLUtils for generalization.


bq. Next thing you highlighted was using o.a.oodt.cas.resource.struct.ResourceNode for ganglia
HOST structure. Since ganglia Host struct contains more ganglia specific attributes, I think
its better to keep away from o.a.oodt.cas.resource.struct.ResourceNode. example NodeId like
atribs are not in ganglia domain.

Agreed I actually wasn't suggesting you extend ResourceNode or anything, simply that your
GangliaHost data structure should also be placed into the o.a.oodt.cas.resource.structs package.
In fact all data structures for this particular subsystem project in general should be placed
there. Make sense?

I'll review the patch now.

Thanks Rajith!

> This will consists with Ganglia XML reader and ganglia metric builder. The received XML
will be parsed and it will creates a node which is a tree structure and also a java list consisting
the stats of the Resource Nodes by holding ganglia metrics. which can be queried as preferred.
