In Ceilometer, when pollsters collect meter from VMs, it used hypervisor on compute-node. Now, I want to write new plugin for ceilometer and not use hypervisor to collect meter, I want to collect meter by a service that is installed on VMs (mean ceilometer get data from service), so I need compute-node must communicate with VMs by IP (private IP). Is there any solution to do this?
Thanks all.
In general the internal network used by your Nova instances is kept intentionally separate from the compute hosts themselves as a security precaution (to ensure that someone logged into a Nova server isn't able to compromise your host).
For what you are proposing, it would be better to adopt a push model rather than a pull model: have a service running inside your instances that would publish data to some service accessible at a routeable ip address.
