AWS Lambda

The logfire.instrument_aws_lambda function can be used to instrument AWS Lambda functions to automatically send traces to Logfire.

Installation

Install logfire with the aws-lambda extra:

pip install 'logfire[aws-lambda]'

uv add 'logfire[aws-lambda]'

poetry add 'logfire[aws-lambda]'

Usage

To instrument an AWS Lambda function, call the logfire.instrument_aws_lambda function after defining the handler function:

import logfire

logfire.configure()  # (1)!


def handler(event, context):
    return 'Hello from Lambda'

logfire.instrument_aws_lambda(handler)
  1. Remember to set the LOGFIRE_TOKEN environment variable on your Lambda function configuration.

logfire.instrument_aws_lambda uses the OpenTelemetry AWS Lambda Instrumentation package, which you can find more information about here.
