OpenTelemetry is an open source observability framework that offers powerful capabilities in monitoring metrics, logs, and traces. It has garnered significant attention due to its vendor-neutral approach, allowing users to instrument once and send data to any backend for processing and storage. Lumigo takes OpenTelemetry's capabilities a step further by providing near-instantaneous insights into application performance, making it easier to grasp the nuances of microservice performance. Instrumentation is essential in adding extra code to microservices to generate trace data, with manual instrumentation currently being used for languages like Golang before fully automated, 1-click OpenTelemetry becomes available. Lumigo provides a simple initialization function to set up OTel tracing, which can be easily integrated into existing services using middleware or by passing the token as an environment variable. The framework also offers visualization tools, allowing users to gain deep insights into service performance without the burden of running their own trace storage and processing. OpenTelemetry is invaluable for tracking down performance issues or troubleshooting unexpected behavior in Golang microservices, offering flexibility and operational overhead benefits.
