This refactors the initial implementation of chunk metrics and attempts to make them consistent and more usable by queries/dashboards wishing to show things like:

  • discarded refs %
  • discarded series %
  • discarded chunks %
  • discarded chunks per batch histograms
  • post-filter refs %
  • post-filter series %
  • post-filter chunks %
  • post-fillter chunks ber patch histograms (effective batch size)
