# sdk-config.yaml is a typical starting point for configuring the SDK, including exporting to
# localhost via OTLP.
# NOTE: With the exception of env var substitution syntax, SDKs ignore environment variables
# when interpreting config files.
#
# This template includes env var substitution references (i.e. ${MY_ENV}) for all spec defined
# env vars (https://opentelemetry.io/docs/specs/otel/configuration/sdk-environment-variables/)
# which map cleanly to file configuration. For example, OTEL_SDK_DISABLED is referenced below,
# but OTEL_TRACES_EXPORTER is not since it does not map well to the hierarchical structure of
# file configuration.
#
# Because env vars are ignored except for env var substitution, if "disabled: ${OTEL_SDK_DISABLED:-false}"
# is replaced with "disabled: false", setting OTEL_SDK_DISALBED env var will not have any effect.
# See https://opentelemetry.io/docs/specs/otel/configuration/file-configuration/ for more information.
# The following spec defined env vars are NOT referenced and are thus ignored:
#
# - OTEL_RESOURCE_ATTRIBUTES
# - OTEL_LOG_LEVEL
# - OTEL_PROPAGATORS
# - OTEL_TRACES_SAMPLER
# - OTEL_TRACES_SAMPLER_ARG
# - OTEL_EXPORTER_ZIPKIN_ENDPOINT
# - OTEL_EXPORTER_ZIPKIN_TIMEOUT
# - OTEL_EXPORTER_PROMETHEUS_HOST
# - OTEL_EXPORTER_PROMETHEUS_PORT
# - OTEL_TRACES_EXPORTER

# - OTEL_LOGS_EXPORTER
# - OTEL_METRICS_EXEMPLAR_FILTER
