OpenStack system usage events

Table of contents
No headers

System usage events are generated by certain activities such as deploying or re-sizing an instance. Periodic events are also generated for all instances that had no activity during an audit period. This means that for each audit period, Cloud Cruiser can reconstruct all activity and allocations in order to compute costs and load data for reporting.

For more information, see http://wiki.openstack.org/SystemUsageData
