Hello,
Is there any way to use Ganglia to monitor virtual machines? Right now I'd
like to get data from libvirt's api (CPU usage, IO, Network etc), but I
don't want to reinvent the wheel and I'd like to use already mature tools
to do that, for example Ganglia. I know collectd has plugins which support
libvirt, but from what I've read, ganglia could be better solution.
1st question is: how can I monitor virtual machines in Ganglia. Especially
using libvirt, but later also Xen, VMware, Hyper-V. Is it possible? Can
ganglia monitor virtual machines? What can I monitor without additional
agent on guest and what can I monitor with such agent?
2nd question: I've just found out gmetad-python, but before I'll try to use
it I'd like to ask about possibilities to use python scripts to collect
data from gmond. What is the easiest way to do that?
I'm interested in python, because I'd like to try create simple Openstack
and Ganglia proof of concept. I was going to use existing simple monitoring
around libvirt from openstack and implement storing data in RRD files, but
as I've mentioned above, I don't want to reinvent the wheel and I think a
better way is to integrate already existing solutions. The question is how
to integrate those two projects. My first step is to run gmond on each
host, collect data from it via python script, save those data into RRD file
and use this data in Openstack's environment. If gmetad-python can do that,
it's great. Then second step will be to get that data from gmetad-python
(via python script) and use it in Openstack's environment.
Cheers,
