As a non-admin user of open-stack, I do want to obtain how many vms our of the total quota are running at a specific time.
I do want to monitor usage of such resources by writing a collectd plugin for it.
I observed that there are already two types of collect plugins related to open-stack but none of seems seem to address this simple use case: a user that wants to monitor his own usage of these resources.
- collectd-openstack which seems not to be maintained and that seems to require admin rights, a deal-breaker limitation
- collectd-ceilometer-plugin which is mostly the oppisitve thing: feeding data captured by collectd to ceilometer.
I don't care about the state of the entire cloud, I am interested only about usage inside my project.
How API should I use in order to obtain this informations? Funny, most of the information I need is already published on the web dashboard. Still, I need to capture it with python/collect in order to send it to other systems for processing.
