aws-cdk-lib.aws_lambda.AdotLambdaExecWrapper

AdotLambdaExecWrapper Enum

The wrapper script to be used for the Lambda function in order to enable auto instrumentation with ADOT.

Note: These wrappers are for the legacy ADOT Lambda layers with an embedded collector. The recommended optimized ADOT Lambda layers use /opt/otel-instrument set via the AWS_LAMBDA_EXEC_WRAPPER environment variable directly.
