Injecting trace IDs into logs is a crucial technique for correlating log entries from different services or components in a distributed system. This method enables developers and operators to track the flow of a request across various parts of the system, making it easier to diagnose issues, understand system behavior, and optimize performance.

1. Generate Unique Trace IDs

A trace ID is a unique identifier for each request or transaction that flows through the system. It should be generated at the entry point of our distributed system, such as the first service that receives the request from the outside world. We can use various methods to generate a trace ID, including UUIDs (Universally Unique Identifier) or other unique string formats that ensure no two requests have the same identifier.

There are several methods to generate a trace ID, each with its benefits and use cases. Here are some of the most…
