Configuration

The Rotel Lambda Extension is configured using the same environment variables documented for the Rotel collector, documented here.

To ease configuration for Lambda environments, you can set ROTEL_ENV_FILE to the path name of a file and that file will be interpreted as an .env file. For example, set ROTEL_ENV_FILE=/var/task/rotel.env and include the following rotel.env file in your function bundle:

ROTEL_OTLP_EXPORTER_ENDPOINT=https://api.axiom.co
ROTEL_OTLP_EXPORTER_PROTOCOL=http
ROTEL_OTLP_EXPORTER_CUSTOM_HEADERS="Authorization=Bearer ${AXIOM_API_KEY},X-Axiom-Dataset=${AXIOM_DATASET}"

The values ${AXIOM_API_KEY} and ${AXIOM_DATASET} will be resolved from the environment of the function, allowing you to set the secret values in your AWS Lambda function definition and out of the on-disk file.
