Hey @sttts, could you help clarifiy some of the metrics you mention so we are on the same page:

Time-to-Change/Provision [ mean / percentile ] (= "Time to Readiness") – The initial change. Can be the result of detecting a non-Crossplane change to the system or something initiating by the control plane or git/webhook

Not sure what exactly is qualified as a "change to the system". Is this something like: Time from when there is a change of/creation of the kubernetes resource (MR/Claim) up to when its reconciled/updated/provisioned externally and Ready? The change can come from a gitops workflow or XP creating/updating an MR based on a composite.

Time-to-Detect[ mean / percentile ] – This is when Crossplane first becomes aware that something has changed, and it now needs to reconcile.

Is this one related to when Crossplane detects that something has changed on the external resource, and then the time to detect and reconcile it? The one you created a PR for?

Time-to-Reconcile[ mean / percentile ] – This is when we have successfully reconciled an event (and includes cloud provider time to provision).

This one I understand as time from CreationTimestamp up to when its Synced: True, Ready: True? Is that correct?

Exceeding-Time-to-Reconcile [ mean / percentile ] – The time it takes more than the default reconcile interval, counting everything faster as zero. This number should low'ish. It correlates with the queue length, but is more understandable.

This one is the most confusing to me. What is the default reconcile interval? Is it the poll-interval? And then we measure the time it took to reconcile more then that? So if there is a queue, it could be longer.

@ezgidemirel is there more to do in this epic before we can close it out? If there is more, would you be able to update the tasklist so it captures all the planned work still to be done? 🙇‍♂️

@jbw976 updated the list.
