In modern microservice architectures, requests often span multiple services, making it challenging to monitor and debug performance issues. Distributed tracing provides the ability to follow a request’s journey through these services, identifying performance bottlenecks and dependencies. The W3C trace context standard simplifies this process by introducing two critical headers: traceparent and tracestate.

Implementing distributed tracing with OpenTelemetry helps track requests across services, providing insights into performance and pinpointing issues.

You may have wrestled with a web application attempting to call an offsite web service, such as an OpenTelemetry Collector, and gotten an odd error with the word CORS in it. Something like: Or, maybe you got a generic thrown error from your fetch statement that states Error: Failed to fetch …and you wondered, “What’s the problem, and how can I fix it?” These kinds of errors are called CORS errors, and they can be a bit confusing.

Complexity rules the day within the world of data systems and pipelines. A goal for any observability practice is to help reduce complexity and give users and administrators a clear view of what’s happening in any system. This is the path to unified observability, a mature system where monitoring and troubleshooting are streamlined. This has been difficult to achieve for many organizations.
