Hi Srini,
We had conduct an Q&A session during last MultiCloud weekly
meeting , the purpose is to dive into more details of intent/design of this HPA
telemetry so that we can judge whether it fits into multicloud’s scope and how
it should be incubated inside Multicloud . Please refer to the MOM
(https://wiki.onap.org/display/DW/MOM+of+Aug.+29th+2018+MultiCloud+weekly+meeting
) for details, I also copied the questions/answers here to facilitate the
further discussion/feedback:
HPA Telemetry
Q&A:
Q: Delivery plan:
A: Start it in C. Release, no commitment what can be delivered
Q: Seed code:
A: N/A
Q: Deployment topology: will be a single collector running for any kind of
underlying VIM/Cloud type.instance?
A: Not clear yet.
Q: Configuration API/portal:
A: N/A for now, but eventually be there,
Q: Will the API/IM be generic to be VIM/Cloud agnostic ?
A: not clear yet
Q: Is there any dependency to AAI model/schema
A: There is a schema change to AAI in progress (Dileep)
Q: Is this schema be generic (VIM/Cloudagnostic?)
A: Supposed to be generic
Q: Will the collector? Be impacted by different agent on VIM/Cloud ?
A: not clear yet
Q: Why not DCAE VES collector /microservice? Please evaluate this option.
A: no answer yet
suggestion (Bin Yang<https://wiki.onap.org/display/~biny993> ) If there can be
just 1 collector for all VIM/Cloud instance/types, you can have dedicate repo
Otherwise, share the existing repos following the broker/plugin topology
AI: Eric Multanen<https://wiki.onap.org/display/~ewmulta> figure out the
questions above, then decide whether a dedicated repo needed.

Hi Frank,
Please see following links:
Intent and high level architecture is presented in various groups:
https://wiki.onap.org/display/DW/Edge+Scoping+MVP+for+Casablanca+-+ONAP+Enhancements#EdgeScopingMVPforCasablanca-ONAPEnhancements-AggregatedInfrastructureTelemetryStreams(AlignswithHPArequirements,CombiningeffortswithHPA)
Dileep started design page at (Telemetry for OOF and A&AI)
https://wiki.onap.org/pages/viewpage.action?pageId=38116734
There is no design page yet for HPA Telemetry for Multi-Cloud. But there are
set of JIRA request on the following EPIC:
https://jira.onap.org/browse/MULTICLOUD-257
Thanks

Hi Srini,
This topic has been discussed in the OOF group as well. Is there a wiki page,
slide deck, or other material describing the proposed design? Thanks

Bin,
Thank you for the agenda slot today, I think we covered most of everything –
the call dropped promptly on the hour.
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

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

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

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.
Thanks
Srini
