Hello Greg, I don't think there is one approach to reach the one telemetry solution for OpenStack. It depends on your needs, the ecosystem around or present and so on. The services of OpenStack (ceilometer,aodh) and also gnocchi are very divers in its possibilitys to configure and use. I'm not so deep in all of these services, but in my opinion there are multiple solution. Look for example to the respective deployment tools around OpenStack and what they will do. There are working many capable people with also the feedback from multiple deployments in different environments and use cases. So possibly there are thoughts for you. We use kolla-ansible approach [1] but as an example there are others out there [2] [1] https://docs.openstack.org/kolla-ansible/latest/reference/logging-and-monito...

Weitere Informationen, warum dies wichtig ist, finden Sie unter https://aka.ms/LearnAboutSenderIdentification ] OUTSIDE-EPG! Hey ... I am working in OpenStack StarlingX which supports a Kubernetes cluster and a containerized OpenStack cluster (via openstack-helm). Our OpenStack offering is fairly simple ... only running Nova, Cinder, Neutron, Keystone, Glance, Horizon and Heat ... @ Antelope. In a predecessor of StarlingX, maybe in the Queens(?) timeframe ... we had a Telemetry solution that consisted of: - Ceilometer (for basic data polling, notifications and collection) - Panko (for event DB) - Gnocchi (for time-series DB) - Aodh (for alarming based on metric thresholds, etc.) HOWEVER ... today (Caracal) ... - I think Gnocchi is still alive and well ... https://eur04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fgnocchixyz%2Fgnocchi&data=05%7C02%7Cjoern.kaster%40epg.com%7C6daa096897bf43ad2ef208dcdd78d81a%7Cd560862d1a634bec968adb98247481f5%7C0%7C0%7C638628758323428757%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=Z5hJKcjoo%2FHp17tbmlZtw3H2od3prSWa%2FTS3ErC1m4k%3D&reserved=0<https://github.com/gnocchixyz/gnocchi> * but maintained outside of OpenStack - I think OpenStack Panko was deprecated in ~ Wallaby ? * and don't think(?) it is maintained outside of OpenStack ? - The OpenStack Landscape at https://eur04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fwww.openstack.org%2Fsoftware%2F&data=05%7C02%7Cjoern.kaster%40epg.com%7C6daa096897bf43ad2ef208dcdd78d81a%7Cd560862d1a634bec968adb98247481f5%7C0%7C0%7C638628758323440855%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C0%7C%7C%7C&sdata=dP7MHE2AfXkZ03B522v0vNV%2Ba%2Bff1aYqhEnrh7Z18QY%3D&reserved=0<https://www.openstack.org/software/> * shows only Ceilometer and Aodh MY QUESTIONs : ----------------------- - so what are the current recommendations for OpenStack Telemetry ? - is it just Ceilometer and Aodh ? * Does Ceilometer provide DBs ? (like it used to a long time ago) - is Gnocchi (although maintained outside of OpenStack) still supported in the OpenStack environment as a DB option ? - what is used for event DB ? ... now that panko is gone ... Gnocchi ? Ceilometer ? - are there actually multiple options/solutions for OpenStack Telemetry ? e.g. * Ceilometer / Gnocchi / Aodh * Ceilometer / External Elastic Solution / Aodh * Others ? Greg.
