Ceilometer deployment notes
Overview
Fuel has the ability to deploy OpenStack Telemetry component Ceilometer. The main aim of Ceilometer is to collect and share measurement data gathered from all OpenStack components. This data could be used for monitoring and capacity planning purposes as well as for an alarming service. Ceilometer's REST API could also serve as source of data for external monitoring software of customer's billing system.
Installation
Ceilometer can be installed in Fuel by checking the appropriate check box when configuring your environment. Ceilometer is supported by CentOS and Ubuntu.
Notes
Ceilometer collects a number of metering data and performs a high volume of database writes. It could be up to 13000 writes per hour for only 400 resources inside the cloud. Currently in Fuel 4.0i, Ceilometer uses only common MySQL database, thus we do not recommend to deploy standard Ceilometer for large production installations.
Also please note that Notification bus support for Ceilometer is not a part of 4.0 release, due to a number of issues with MySQl backend12. Implementation is planned in 4.1.
Horizon Metering Panel disabled in 4.0. This panel requires the metadata_query. Ceilometer feature that is not supported by Ceilometer with MySQL driver3. A significant portion of the Metering panel is removed in the Havana release because this part displays inconsistent data.4.
