Hi @arghya88. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

What was the number of releases before it gets removed? Worth putting that in the Release Note. Also [ACTION REQUIRED]

[ahg-g]

please update the release note as follows:

"[ACTION REQUIRED] scheduler alpha metrics binding_duration_seconds and scheduling_algorithm_preemption_evaluation_seconds are deprecated, Both of those metrics are now covered as part of framework_extension_point_duration_seconds, the former as a PostFilter the latter and a Bind plugin. The plan is to remove both in 1.21"

What was the number of releases before it gets removed?

Those metrics can be removed immediately since they are alpha, but we will remove them in the next cycle.

@ahg-g updated release note

[alculquicondor]

Those metrics can be removed immediately since they are alpha, but we will remove them in the next cycle.

I remember that adding DeprecatedVersion caused other metrics to stop being exported at some point, even if we still put data from the scheduler code.

I remember that adding DeprecatedVersion caused other metrics to stop being exported at some point, even if we still put data from the scheduler code.

Right, the metric is alpha so it will stop exporting them directly (not sure if it will continue to export them if the metric was Beta), but admins can still pass a flag to the component to continue to export them.
