      Story (Required)

      As a <PERSONA> trying to <ACTION> I want <THIS OUTCOME>

      As a cluster admin or service first engineering team for openshift pipelines on konflux, I want to be able to properly define to App SRE's tiger team how to interpret and triage our various alerts when they fire.

      <Describes high level purpose and goal for this story. Answers the questions: Who is impacted, what is it and why do we need it? How does it improve the customer’s experience?>

      Background (Required)

      See https://docs.google.com/presentation/d/17aRQbg-EjjL8yyzT2YTNe80Ubtb0Dt93t9tmDnW_qPM/edit#slide=id.p for the initial presentation to app sre tiger team and konflux infra on our SLO/SLI/SLAs

      The current doc locations that we will add updates to as a result of our metrics and progression in providing debug

      <Describes the context or background related to this story>

      Out of scope

      <Defines what is not included in this story>

      Approach (Required)

      Some key items to make sure our documented, aside from the new alerts

      • tuning options for controller threads, k8s qps, burst for not just core controller, but chains and results not available from our gitops repos
      • upcoming webhook tuning
      • soon to be ready enablement of pprof minimally on results, and perhaps across the board since golang says it is safe to run in production, so app sre can get goroutine dumps for deadlocks
      •  

      <Description of the general technical path on how to achieve the goal of the story. Include details like json schema, class definitions>
