Sending OpenTelemetry Data From AWS Lambda to Honeycomb

The post outlines a comprehensive guide on how to send OpenTelemetry (OTel) data from an AWS Lambda instance to Honeycomb using Python and the AWS Serverless Application Model (SAM). It emphasizes the challenges of integrating AWS Lambda, Honeycomb, and OpenTelemetry due to the fragmented nature of existing documentation and aims to simplify the process with a practical example. The guide covers several key steps, including adding the AWS Distro for OpenTelemetry (ADOT) Lambda layer, configuring the OTel Collector to export data to Honeycomb, and securely storing Honeycomb API keys in AWS Secrets Manager. It also discusses the rationale for using OpenTelemetry as a vendor-neutral standard and highlights the rich query capabilities of Honeycomb's observability platform. Additionally, the post addresses potential issues, such as an ImportError related to urllib3, and provides solutions to enhance the observability of AWS Lambda functions through OpenTelemetry and Honeycomb integration.
