Hey Thomas 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.

Hello Team We are a public cloud provider based on Openstack. We are working to create Autoscaling with aodh and senlin in Kolla-ansible Openstack Wallaby release.

We were looking if anybody in the community has ever used this feature.
Hi, Not only we use that feature in production, but I also used the dynamic pollster stuff on the compute pollster using the command-line thingy. The result is this project: https://urldefense.proofpoint.com/v2/url?u=https-3A__salsa.debian.org_openstack-2Dteam_services_ceilometer-2Dinstance-2Dpoller_&d=DwIDaQ&c=euGZstcaTDllvimEN8b7jXrwqOf-v5A_CdpgnVfiiMM&r=58AkTXQK-t27foam0JxQj_p2S7oML-5RlT2bY2LISOk&m=KrUyOp7R8Eq0a_TOSOboQA2IOuHFlEtSswxM7uAB0f4&s=PZG_y8gQzPmKPmaCX1OWHNA5Zg9tFJ0O4zdZZkrUnIY&e= You can also read bits of docs of OCI about it: https://urldefense.proofpoint.com/v2/url?u=https-3A__salsa.debian.org_openstack-2Dteam_debian_openstack-2Dcluster-2Dinstaller-23configuring-2Da-2Dcustom-2Dmetric-2Dand-2Dbilling&d=DwIDaQ&c=euGZstcaTDllvimEN8b7jXrwqOf-v5A_CdpgnVfiiMM&r=58AkTXQK-t27foam0JxQj_p2S7oML-5RlT2bY2LISOk&m=KrUyOp7R8Eq0a_TOSOboQA2IOuHFlEtSswxM7uAB0f4&s=HB4uQxN4HzA-iHQ1Cvlt-UVhF6oH5jzY0xmJ8Afu5i8&e= I hope this helps.
