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.
