Re: [Xen-devel] Question about CPU utilization
Just so somebody doesn't go off and duplicate a bunch of effort, this
seems like a good time to announce that I've already written a
considerable amount of code that provides detailed measurements of cpu
usage for each domain along with some other interesting bits of data,
for instance domain context switch frequency, etc. The code consists of
some hooks in xen itself to record data, and an app that runs in Dom0
that grabs the data and presents it either as a periodically updating
text screen, or as semi-processed data through a network socket for use
by other programs.
I'd like to make this code available to everyone by checking it in to
the xen source, perhaps having the code activated through a build option
or something. Then we can discuss the various ideas for the best
interface to this data, snmp or whatever.
