Thank you - great follow-up questions.
Teams are both dedicated to the overall health and individual teams own their pipelines – a bit of both!
As an owning team (Engineer or Manager) it would give an overview of, are things healthy? It would also help inform in a proactive manner if time/energy needs to be spent on further optimization.
Not really for the purpose of reactive - that should be handled by automated alerting. This is more for passive review.
Pipelines of all sorts of shapes/sizes.
An argument could be made to export all of this data into an Observability product and create the appropriate customized graphs/metrics. I am not opposed to that but that is an entirely different scope of ask/work for most folks I would assume.
