Edit the interval values in the /etc/ceilometer/pipeline.yaml file. The interval values are specified in seconds, so 600 seconds is 10 minutes. You may need to restart the Ceilometer service for the change to take effect.

In the default pipeline.yaml file the interval value for the meter_pipeline sets the default interval for all meters (as indicated by setting meters to * in the corresponding block).

The interval value is then repeated for the cpu_pipeline, which is included in the file so that some additional settings related to the transformation of the cpu meter can be supplied. A full list of available meters is available in the documentation at http://docs.openstack.org/developer/ceilometer/measurements.html
