Epic Goal

Allow user to define their own metrics by leveraging the FLP configuration, exposing some parts of it more explicitly.

Why is this important?

As long as we develop new features, more data is accessible in flows but not necessarily available as metrics and/or not necessarily in a shape that customers want (e.g. in terms of labels).

Metrics are becoming more and more a key part of NetObserv for at least two reasons:

• the ability to create alerts
• the "lokiless" use case gaining traction, which still produces metrics

Providing the ability for customer to define their own metrics with a CRD-based API will allow them to get exactly what they want.

Moreover, on the engineering side, this is offloading some maintenance aspects so we don't need to maintain a list of available metrics manually and potentially having to amend it from RFEs.

Lately, engineers have been asked to add metrics for RTT and for Drops stats. With a new API, customers wouldn't have to wait for the next release(s) to get them.

Planning Done Checklist

The following items must be completed on the Epic prior to moving the Epic from Planning to the ToDo status

• Priority+ is set by engineering
• Epic must be Linked to a +Parent Feature
• Target version+ must be set
• Assignee+ must be set
• (Enhancement Proposal is Implementable
• (No outstanding questions about major work breakdown
• (Are all Stakeholders known? Have they all been notified about this item?
• Does this epic affect SD? {}Have they been notified{+}? (View plan definition for current suggested assignee)
  1. Please use the "Discussion Needed: Service Delivery Architecture Overview" checkbox to facilitate the conversation with SD Architects. The SD architecture team monitors this checkbox which should then spur the conversation between SD and epic stakeholders. Once the conversation has occurred, uncheck the "Discussion Needed: Service Delivery Architecture Overview" checkbox and record the outcome of the discussion in the epic description here.
  2. The guidance here is that unless it is very clear that your epic doesn't have any managed services impact, default to use the Discussion Needed checkbox to facilitate that conversation.

Additional information on each of the above items can be found here: Networking Definition of Planned
