Re: [openstack-dev] [Ceilometer] Doubt about data recollection
Hello, In the end the RabbitMQ approach would not suffice our requirements as in our installation we have RabbitMQ in the controller. I'm trying to do it with the pipeline approach but trying to maintain the API working. I did the following with cpu_util: - name: cpu_sink transformers: - name: "rate_of_change" parameters: target: name: "cpu_util" unit: "%" type: "gauge" scale: "100.0 / (10**9 * (resource_metadata.cpu_number or 1))" publishers: - notifier:// - udp://127.0.0.1:31337 I want to publish it in both channels but, when this is done, neither work. If I try sending only data thought UDP it also refuses to work. Any clues on this? I'm testing it with netcat listening to that port. Also, is it possible to send an AMQP message to other IP that is not the one of the controller? In the documentation only makes reference to the options available for this kind of message, there is no place to specify the host. Thanks for your support, Alberto.

Re: [openstack-dev] [Ceilometer] Doubt about data recollection
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.

[openstack-dev] [Ceilometer] Doubt about data recollection
Hello, Istarted working with OpenStack's ceilometer recently and I have some questions that I can not resolve with the documentation I have found. I would like to have the telemetry of a node inside the node itself (for example, a virtual machine that resides in that node and processes the local information in some way) without passing through the global scope (Ceilometer API with the default settings). Is it possible? I have read about agent plugins and it may be a way to approach to the solution (http://docs.openstack.org/developer/ceilometer/contributing/plugins.html). Best regards, Alberto.
