Project Mission

To reliably collect measurements of the utilization of the physical and virtual resources comprising deployed clouds, persist these data for subsequent retrieval and analysis, and trigger actions when defined criteria are met.

Road Map

The future direction and plans of the project can be found here.

Ceilometer Extensions

Ceilometer's goal is to handle the Telemetry requirements of an OpenStack environment; this includes use cases such as metering, monitoring, and alarming to name a few. The scope of these uses cases are diverse and beyond the scope of a single project and team. However, additional functionality can be found in external projects to enhance the Ceilometer experience. Some projects exist outside the management of the Ceilometer team but may be adopted in the future. The following are known extensions that supplement the capabilities of Ceilometer:


  • Aodh - Alarming service that provides threshold and event alarming functionality (originally contained in Ceilometer)
  • Gnocchi - Scalable time-series database and resource indexing service

Externally Managed

  • Heat - Orchestration service which provides autoscaling capabilities using Ceilometer data
  • Horizon - UI service which provides visualisation of Ceilometer data
  • PowerVM - PowerVM pollster plugin
  • CloudKitty - OpenStack Rating as a Service component and usage reporting
  • Graphite Publisher - Ceilometer publisher to connect to Graphite.
