-# OpenTelemetry distributed tracing (Traces only, opt-in).
-# Existing API and Queue spans are exported to an OTLP http/protobuf endpoint.
-#
-# Standard OTEL_* environment variables are honored for values omitted below:
-# OTEL_EXPORTER_OTLP_TRACES_ENDPOINT, OTEL_EXPORTER_OTLP_ENDPOINT,
-# OTEL_EXPORTER_OTLP_HEADERS, OTEL_TRACES_SAMPLER, OTEL_TRACES_SAMPLER_ARG, etc.
-#
-# When this is enabled together with sentryForBackend, Misskey shares Sentry's
-# TracerProvider and adds an OTLP SpanProcessor to it. In that mode:
-# - sampleRate below is ignored; sampling follows sentryForBackend.options
-#   tracesSampleRate / tracesSampler.
-# - resourceAttributes below is ignored; set OTEL_SERVICE_NAME and
-#   OTEL_RESOURCE_ATTRIBUTES in the environment if you need to override them.
-# - spans produced by Sentry integrations are exported to both Sentry and OTLP.
-# - sentry-trace / baggage propagation to outbound remote requests is disabled
-#   by default while OTel is enabled. Set propagateTraceToRemote: true only if
-#   you intentionally want Sentry trace propagation for your deployment.
