Hey Thomas<br>
This was really helpful. I had another doubt, how can I add a complex calculation such as taking mean of CPU utilization of all nodes that are present in a senlin cluster with senlin cluster ID as its primary key.</div>

to generate a pollster to collect data for senlin. We were looking if anybody in the community has ever used this feature.<br>
<br>
Hi,<br>
<br>
Not only we use that feature in production, but I also used the dynamic <br>
pollster stuff on the compute pollster using the command-line thingy. <br>
The result is this project:<br>

You can also read bits of docs of OCI about it:<br>
