id: otel-migration-warning title: Telemetry deprecated in favor of OpenTelemetry version: v50+ -> v54 description: | The go-metrics based telemetry package is deprecated in v0.54 in favor of OpenTelemetry. The Cosmos SDK is moving towards the OpenTelemetry standard for observability and metrics collection.

The legacy go-metrics telemetry helpers (telemetry.NewLabel, telemetry.IncrCounter, telemetry.SetGauge, telemetry.MeasureSince, etc.) are still functional but deprecated. New code should use OpenTelemetry directly.

What this spec does:

  • Detects go-metrics telemetry usage patterns
  • Emits an end-of-run warning about the deprecation
  • Does NOT apply any automatic changes (migration is context-dependent)

What you need to do:

  • Evaluate your telemetry requirements
  • Plan a migration to OpenTelemetry if you use telemetry
  • Update telemetry calls to use OpenTelemetry APIs
  • Remove dependency on github.com/hashicorp/go-metrics when possible

upstream_sources:

  • docs://upgrading/v0.54
  • docs://changelog/v0.54-breaking
