  • Graduate kubelet CPUManager to GA
  • Other comments:
    The PR is organized as follows:
  1. the first commit is a translation as more mechanical as possible from the ancient document format to the newest available at moment of writing. Care is taken to alter as little as possible the original content, with the only purpose to make it fit in the new format
  2. the second commit adds all the new information not required when the original document was written, mostly concern with the PRR reviews.
  3. the third commit start updating the content with the plans to GA in 1.26
  4. the fourth (and following, if needed) commit adds the new content required by the new format, questionnaires.

  • After 30d of inactivity since lifecycle/stale was applied, lifecycle/rotten is applied
  • After 30d of inactivity since lifecycle/rotten was applied, the issue is closed

You can:

  • Mark this issue or PR as fresh with /remove-lifecycle stale
  • Mark this issue or PR as rotten with /lifecycle rotten
  • Close this issue or PR with /close

node: cpumgr: add metrics information
e1d1af1 
During the review of the KEP, it emerged there are possible
metrics we should add, tracking admission and errors.
CPU allocation is done at admission time, and extracting
these metrics is expected to be both cheap and useful for monitoring.
