Warning

We discovered a breaking change in the OTLP endpoint: OpenTelemetry attribute names starting with underscore, for example _attrib, are no longer automatically translated to key_attrib. Please use 3.7.1 instead for OTLP ingestion.

Changelog

• [CHANGE] Remote-write: the following metrics are deprecated:
  • prometheus_remote_storage_samples_in_total, use prometheus_wal_watcher_records_read_total{type="samples"} and prometheus_remote_storage_samples_dropped_total instead,
  • prometheus_remote_storage_histograms_in_total, use prometheus_wal_watcher_records_read_total{type=~".*histogram_samples"} and prometheus_remote_storage_histograms_dropped_total instead,
  • prometheus_remote_storage_exemplars_in_total, use prometheus_wal_watcher_records_read_total{type="exemplars"} and prometheus_remote_storage_exemplars_dropped_total instead,
  • prometheus_remote_storage_highest_timestamp_in_seconds, use the more accurate prometheus_remote_storage_queue_highest_timestamp_seconds instead in dashboards and alerts to properly account for relabeling and for more accuracy. #​17065
