For performance, metrics and scaling tasks there is a strong need to have various components/code instrumented (call times, error counts, roundtrip times...). Currently ceilometer has similar data but different fundamental requirements so this session should talk about whether to augment ceilometer with this data or create a new tool. New code 'decorators' (which are not relevant to ceilometer) need to also be added to gather this information.
Many stackers are depending on OpenStack for large scale and revenue generating operations. In these environments, it is critical to monitor the health and optimize the performance of OpenStack components.
