• agent/clusterReceiver: Upgrade receiver.prometheusreceiver.RemoveLegacyResourceAttributes feature gate to beta stability (enabled by default) (#32814)
  Disable the receiver.prometheusreceiver.RemoveLegacyResourceAttributes feature gate to restore previous behavior. This feature gate will be removed in a future release.
  The feature gate is used to remove the following legacy resource attributes:
  net.host.name -> server.address
net.host.port -> server.port
http.scheme -> url.scheme
  • If you're using Prometheus receivers with the collector agent or cluster receiver, and have alerts or dashboards based on that data, please review the upgrade guidelines.
