Open Stack

Hi Girija Sharan,

as my master degree thesis I have done a framework for virtual machine
migration in OpenStack, which I think it might be useful for what you're
realizing.

I have extended Ceilometer and OpenStack Neat, a framework for virtual
machine consolidation.
I had to collect samples of cpu and memory utilization of compute nodes.

Here is the source code of the Ceilometer extension
https://github.com/MisterPup/Ceilometer-Juno-Extension
In the following url you can find the extension to Openstack Neat
https://github.com/MisterPup/OpenStack-Neat-Ceilometer

If you have any questions, please feel free to ask.

Best regards,
Claudio

> Hi All,
>
> This query is about Ceilometer, and its my sincere request to you to read
this till end and understand properly.
>
> Let me first put up my requirement :
> 1). I need to develop a monitoring tool for my infrastructure, which will
show me the live CPU usage, Memory usage, Disk usage, and Network traffic
of instances launched on Compute nodes as well as of physical Compute nodes.
>
> To achieve this I explored Ceilometer service of Openstack (metering part
only) and found that, it has many meters using which I can retrieve above
mentioned live data but only of instances launched, not of physical Compute
nodes.
>
> Now moving to my queries :
> 1). How do I create corresponding meters to retrieve above mentioned
details of physical Compute nodes (like memory.usage, cpu_util,
network.incoming.bytes, etc.. which exists for instances).
> 2). Please do point me towards some helpful links or let me know the
exact way of doing so.
> 3). Why don't we add Monitoring service to Openstack. As Admin user will
be needing to see all these details related to Compute nodes and other
nodes.
>
> Now been said that, I came up with an idea which I would like to share
here :
>
> As part of VM migration, one has to know the load on Compute nodes,
depending on which Admin will be deciding whether to migrate the VMs or not
and to which Compute node.
> Now just think if VM migration need to be done automatically (when some
specified threshold value reaches), one need to collect these metrics from
Compute nodes.
>
> We can make use of these existing Ceilometer's meters (metering part of
Telemetry) and adding more additional meters to retrieve details from
Physical nodes, to create Monitoring Service as well.
>
> Thanks in advance and early responses will be highly appreciated.
