Greetings, I am researching alternatives to the MDS utility previously included in the Globus 4.x toolkit. The current iteration of the Nimbus monitoring plug-ins for Nagios rely on the MDS to act as the public registry for the dynamic state of a cluster, but I would like to evaluate alternatives. The ability for various sites to submit gathered data to a single "master" registry which can then be queried would be ideal. Complicated query support such as XPath is necessary; simple presenting a snippet of XML is all that is required.
If there been any discussion or thoughts regarding an alternative to MDS for resource publishing, I'm very interested to hear about it. Cheers, Adam Bishop University of Victoria
