Bug Description

http://openstack-in-production.blogspot.ca/2014/03/cern-cloud-architecture-update-for.html

Every instance of compute-agent calls nova-api meaning the number of background API calls will grow linearly with the number of compute nodes. This additional load is so big that cern had to redesign there cloud to turn ceilometer compute-agent on.

hi Tim.

there was work done in bug 1293337 to minimise calls to nova api. i'm not sure if solves issue you're seeing in CERN deployment but it'd be good to know if it does.

keeping this open in case we find other optimisations
