fix(alerts): align etcdHighNumberOfFailedProposals description with rate window

[prithvipatil97]

What

The etcdHighNumberOfFailedProposals alert description said proposal failures occurred within the last 30 minutes, but:

• expr uses rate(...[15m])
• for is 15m

So the description matched neither the PromQL window that produces {{ $value }} nor the pending duration.

Fix

Update the description only: 30 minutes → 15 minutes (same pattern as etcdHighNumberOfLeaderChanges, which already says “last 15 minutes” for its 15m window).

No changes to expression, for, severity, or summary.

Why

Misleading for operators reading the alert in consoles / Alertmanager. OpenShift inherits this mixin via cluster-etcd-operator.

Tracked for OpenShift as OCPBUGS-105285.

Test plan

• Diff is description-only
• rate(...[15m]) and for: 15m unchanged

Hi @prithvipatil97. Thanks for your PR.

I'm waiting for a etcd-io 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.

Hello @ahrtr , @ivanvc ,
Good Morning.

I need your attention here.
This is a small fix in the etcd mixin alert etcdHighNumberOfFailedProposals.
The alert description currently says 30 minutes, but both the PromQL window and for are 15 minutes. Kindly check the Jira OCPBUGS-105285 for more information. I have submitted this PR with the fix.

Could you please help with /ok-to-test and an approval review when you get a chance?

This is the upstream PR, After it merges, I will open a follow-up PR in OpenShift cluster-etcd-operator to vendor this update.

Thank you in advance.

Regards,
Prithviraj Patil.
