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

sgordon, Thank you for your reply. However can you please shed some light on this (related to polling period) name: meter_pipeline interval: 60 meters: - "*" transformers: publishers: - rpc:// - name: cpu_pipeline interval: 60 meters: - "cpu" There are two interval. which interval is for what?
Here's an example from the installation guide, you may need to modify on 14.04 as I can not recall if it was still using upstart or not: http://docs.openstack.org/project-ins...
This is not an answer, but could not include such big contents in the comment.
So, the question is here is my pipeline.yaml file,
[root@controller ~]# cat /etc/ceilometer/pipeline.yaml

Here the interval is 60 sec for all metrics, but when i do a ceilometer sample-list, it gives me an o/p not consistent with the setting here.
[root@controller ~]# ceilometer sample-list --query resource=30658d79-03ca-4720-ba43-cc872043e7fa --meter=cpu_util
+--------------------------------------+----------+-------+---------------+------+----------------------------+

Can someone explain this?
