Hi - I have been using ceilometer in devstack for a while, and what
I used to be able to do is modify pipeline.yaml to set the polling
interval for "name: cpu_source" to 60, and then publish it using
udp. The diff for the changes are below for the Liberty
pipeline.yaml:<br>
<blockquote><small><i>stack@vlab:/etc/ceilometer$ diff
pipeline.yaml.bak pipeline.yaml</i><i><br>
</i><i>10c10</i><i><br>
</i><i>< interval: 600</i><i><br>
</i><i>---</i><i><br>
</i><i>> interval: 60</i><i><br>
</i><i>53c53</i><i><br>
</i><i>< - notifier://</i><i><br>
</i><i>---</i><i><br>
</i><i>> - udp://127.0.0.1:4952</i><i><br>
</i></small></blockquote>
The desired and net effect of these changes in Juno was the I would
get cpu_util samples every minute, but cpu meters every 10 minute,
in the Juno release.<br>
<br>
These same changes in Liberty are not having the same effect. I get
cpu, cpu_util, and cpu.delta every 1 minute. Why are cpu samples
arriving every minute?<br>

Is this a ceilometer bug, or change? Is my understanding of the
desired effect incorrect?<br>
Thanks,<br>
