# opentelemetry.sdk.environment_variables

The OpenTelemetry Python SDK can be configured through environment variables. These variables control behaviors such as exporter selection, resource attributes, span limits, and trace sampling. They follow the conventions defined by the OpenTelemetry specification.

opentelemetry.sdk.environment_variables.OTEL_SDK_DISABLED = 'OTEL_SDK_DISABLED'
  OTEL_SDK_DISABLED

  The `OTEL_SDK_DISABLED` environment variable disables the SDK for all signals Default: “false”

opentelemetry.sdk.environment_variables.OTEL_CONFIG_FILE = 'OTEL_CONFIG_FILE'
  OTEL_CONFIG_FILE

  The `OTEL_CONFIG_FILE` environment variable points the SDK at a declarative configuration file (YAML or JSON). When set, the file is the sole source for SDK construction. Spec-defined `OTEL_*` variables with schema equivalents are ignored. Env vars may still be read indirectly by components the file enables (e.g. resource detectors) and via `${env:VAR}` substitution inside the file. See the OpenTelemetry declarative configuration specification for details.

opentelemetry.sdk.environment_variables.OTEL_RESOURCE_ATTRIBUTES = 'OTEL_RESOURCE_ATTRIBUTES'
  OTEL_RESOURCE_ATTRIBUTES

  The `OTEL_RESOURCE_ATTRIBUTES` environment variable allows resource attributes to be passed to the SDK at process invocation. The attributes from `OTEL_RESOURCE_ATTRIBUTES` are merged with those passed to `Resource.create`, meaning `OTEL_RESOURCE_ATTRIBUTES` takes lower priority. Attributes should be in the format `key1=value1,key2=value2`. Additional details are available in the specification.

      import pprint
      from opentelemetry.sdk.resources import Resource
      pprint.pprint(Resource.create({"will_be_overridden": "bar"}).attributes)
