Has anyone started work on a ''top''-like tool that would show the current CPU and memory usage of domains? I''m thinking of writing something really simple in python, starting from listdoms.py, but want to make sure that someone else isn''t already there. Steve -- Stephen G.

AFAIK, no one has started such as tool but I think it would be useful. Of the top of my head, the scheduler at the moment only export absolute CPU time consumed, not averaged. However, that could be added, or you do some averaging in dom0 based on the information available. Another useful piece of information might be number of events received by a domain. This information should be available in Xen but is probably not exported. Also, Mark Williamson has some patches which export some information on the physical machine to dom0 (type of CPU, memory etc). this might be useful and should be available in xen-unstable soon.

Having something to report domains'' CPU/disk/net usage over an interval (and over the life of the domain) would be useful to have in the tree.
