Ceilometer Units
This page has for goal to normalize the units used in Ceilometer.

Status: this page was approved in the Feb 7th 2013 irc meeting.


 * 1) Whenever a volume is to be measured, SI approved units and their approved symbols should be used.
 * 2) For a given sample, unit should NEVER, EVER be changed
 * 3) When the measurement does not represent a volume, the unit description should always described WHAT is measured (ie: apples, disk, routers, floating IPs, etc)
 * 4) If a previous counter exist measuring something similar, the same unit and division should be used as much as possible
 * 5) Samples (aka meters or counters) should always document their units in Ceilometer (API and Documentation) and new sampling code should not be merged without the appropriate documentation.
