Hi All,
I want to do performance analysis on top of
[openstack,Qauntum,openvswitch] setup. I am interested in the following
metrics.
VM life cycle (creation, deletion, boot..,etc)
VM Migration
Quantum (network, port creation/deletion..,etc)
Are there any performance metric tools/scripts available in openstack ?
If not, how can I do the performance analysis of the above metrics on
openstack quantum setup ? Please help me regarding performance metrics.
I want to know details of the biggest deployment with
[openstack,Qauntum,openvswitch] setup interms of number of tenant
networks, number of compute nodes, number of VMs per tenant.
I do not have numbers I can share, but do have an interest in discussing
methodology for evaluating "scaling" particularly as regards to
"networking." My initial thoughts are simply starting with what I have
done for "network scaling" on SMP systems (as vaguely instantiated in
the likes of the runemomniaggdemo.sh script under
http://www.netperf.org/svn/netperf2/trunk/doc/examples/ ) though
expanding it by adding more and more VMs/hypervisors etc as one goes.
While netperf (or its like) is simply a microbenchmark, and so somewhat
removed from "reality" it does have the benefit of not (directly at
least :) leaking anything proprietary about what is going-on in any one
vendor's environment. And if something will scale well under the rigors
of netperf workloads it will probably scale well under "real" workloads.
Such scaling under netperf may not be necessary, but it should be
sufficient.
happy benchmarking,
rick jones
