[fkanout]

Summery

We face a backport issue for some PRs, due to a big non-backported refactor PR from another team.

List of PRs impacted - Order is important:

• 119061 refactor observability #119211
• chore: Refactors alerts search bar #119104
• [ ] [RAC] Fixes terminology and splits tests to new case #120335
  See [RAC] [8.0.0] [META] Manually backport PRs to 8.0.0  #121165 (comment)
• [RAC] Show all alerts, not only "open" workflow status, and remove Workflow filter related logic and clean up the code #120231

AC

• Backport the PR in order manually using the backport script.
• Once your PR is backport-ed successfully, please mention/tag the next PR's owner in the list.
• This issue would be closed once all the listed PRs are backported.

Note

Please feel free to add any other PR that is not backport-ed and not listed above.

I listed the PRs based on the order in our o11y weekly update doc. Therefore we need to start with this one #119211. @ersin-erdal

#119104 was successfully backported with #121194 🎉

I would exclude #120335 from the list cause it depends on a feature PR (#119750) which was blocked and wasn't merged to 8.0 either ahead of feature freeze.

Looks like there's nothing left to merge in this issue, closing now.
