  • Define and collect events for alarm evaluation
  • Trigger alarms based on defined criteria

Starting from the Liberty release, the Telemetry module has changed the gears by enabling more features. This includes the introduction of two additional sub-projects working in tandem with Ceilometer as the core component of the Telemetry service:

  • Aodh service: To handle alarm code functionality
  • Gnocchi service: A dispatcher driver to Ceilometer for archiving metrics storage support

The Telemetry project in OpenStack has been...
