Following are the questions I collected from the discussion - please amend and clarify if I haven’t captured your key questions. I expect Srini and others can assist in providing more detailed/correct answers. 1. Why is this part (Prometheus) of ONAP/multi-cloud instead of Openstack? a. it is used more broadly than just for Openstack SRINI> - This is meant for infrastructure and HPA metrics. - We want to be agnostic to VIM technology - Many constrained Edge deployments would like minimal functions in the Edge - Like nova, neutron, Cinder, HEAT and leave rest to be put in elsewhere. - Prometheus is second only to K8S that got graduated in CNCF (only two so far). - Prometheus has very good integration with Openstack & K8S, AWS, AZURE, Bare-metal nodes including collected. 2. What is the relationship between Openstack telemetry and this proposal? SRINI> Prometheus is mainly meant to collect the metric, aggregate/summation, siliencing etc… Prometheus even have a way collect the metric from Openstack. 3. What is the interface and/or API for configuring rules ? a. Initially, configuration files for the service. 4. How are different cloud / infrastructure type supported? SRINI> Fortunately, Prometheus has various integration with popular cloud technologies already. 5. Where is the datastore of the Prometheus service ? What data/info is accessible by ONAP? a. plan is to develop the HPA statistics exporting/receiving service to provide specific HPA data to ONAP. b. not sure yet if there is a generic access to all data (and whether that is desired) Eric From: Addepalli, Srinivasa R Sent: Tuesday, August 21, 2018 9:36 AM To: [email protected]<mailto:[email protected]>; [email protected]<mailto:[email protected]> Cc: Multanen, Eric W <[email protected]<mailto:[email protected]>>; Ranganathan, Dileep <[email protected]<mailto:[email protected]>>; [email protected]<mailto:[email protected]>; Ranganathan, Raghu <[email protected]<mailto:[email protected]>> Subject: RE: [onap-discuss] [MULTICLOUD] - HPA telemetry Hi Bin, I am travelling. Eric confirmed and he will talk about the feature and high level design. If time permits, Dileep can show the A&AI schema proposal. Hi Ramki and Raghu, Since it is born out of Edge-automation working group, it would be good if you can attend the meeting. Thanks Srini From: [email protected]<mailto:[email protected]> [mailto:[email protected]] On Behalf Of [email protected]<mailto:[email protected]> Sent: Tuesday, August 21, 2018 8:38 AM To: [email protected]<mailto:[email protected]>; Addepalli, Srinivasa R <[email protected]<mailto:[email protected]>> Cc: Multanen, Eric W <[email protected]<mailto:[email protected]>>; Ranganathan, Dileep <[email protected]<mailto:[email protected]>> Subject: Re: [onap-discuss] [MULTICLOUD] - HPA telemetry Hi Srini, Before I can suggest, I would like to understand this feature more. Would someone please present the idea/design to MultiCloud team? Perhaps it's a good chance to do that during the upcoming MultiCloud weekly meeting. Thanks Bin 在 2018年8月21日，23:29，Srini <[email protected]<mailto:[email protected]>> 写道： Hi Bin, We have this EPIC as part of Edge automation: https://jira.onap.org/browse/MULTICLOUD-257 This is meant to ensure that placement decisions consider current available resources in addition to what we were doing with respect to capabilities till R2. This work got started last week. There would some source code development (We call it - HPA Telemetry receiving service) which gets aggregated telemetry information, do any massaging/filtering necessary and updates A&AI DB. There would be some additional development with respect rules for Prometheus aggregation service. This is generic service required across Openstack, K8S and Azure. Is there any repository in Multi-Cloud we can use to put this code or do you suggest to request for a new repository? Please advise.
