Re: [Xen-cim] Requirements and priorities for SLES10 SP1

The SBLIM Data Gatherer package - including some preliminary DMTF Metric model implementation of Xen metrics - is located at

http://sourceforge.net/project/showfiles.php?group_id=128809&package_id=144595

Oliver, do you have a (non IBM-Confidential) doc describing in more detail these metrics that we can share?

Do you have any notes on this that I could see?  I'd like to get the
stats gathering into Xend and the Xen-API soon, so I would certainly
appreciate it if you've got a requirements list for me.

Yes, you certainly _can_ ask for Xen-API to be extended where necessary.
What do you need?  Don't forget, Xen-API is going to be the _only_ off-box API
preserved over the long term.  It's in everybody's interests if the CIM
providers can do everything that they need through that API.  Please,
feel free to ask if there are bits that are missing.
