Backend Changes

⛔ Breaking Changes

• [SPM] Due to a breaking change in OpenTelemetry's prometheus exporter (details)
  metric names will no longer be normalized by default, meaning that the expected metric names would be calls and

  • prometheus.query.normalize-calls: If true, normalizes the "calls" metric name. e.g. "calls_total".
  • prometheus.query.normalize-duration: If true, normalizes the "duration" metric name to include the duration units. e.g. "duration_milliseconds_bucket".
