Hello Gordon, Thanks for your reply.
What we would like to have is access to the data available in Ceilometer API but by local access. For instance, CPU metrics produced at a given node will be consumed in that same node. Probably we will not need all the available data we're yet finding which variables are of our interest. To start with, CPU usage and memory usage are mandatory. I believe that what we are searching is to access directly to compute agent data. Is this possible, for example, subscribing to the RabbitMQ queue where the data is being published by the agent? Is there any other way to do so? Thanks for your support. Best regards, Alberto.
