Learn how to integrate Kafka with OpenTelemetry for enhanced distributed tracing, better performance monitoring, and effortless troubleshooting.

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.

OpenTelemetry can be used to trace Rust applications for performance issues and bugs. OpenTelemetry is an open-source project under the Cloud Native Computing Foundation (CNCF) that aims to standardize the generation and collection of telemetry data. Telemetry data includes logs, metrics, and traces. Rust is a multi-paradigm, general-purpose programming language designed for performance and safety, especially safe concurrency.

Learn how to instrument AWS Lambda functions with OpenTelemetry to gain valuable insights and improve the performance of your serverless apps.

Nodejs is a popular Javascript runtime environment that executes Javascript code outside of a web browser. Express is the most popular web frameworks that sits on top of Nodejs and adds functionalities like middleware, routing, etc. to Nodejs. You can monitor your express application using OpenTelemetry and a tracing backend of your choice.

Nextjs is a production-ready React framework for building single-page web applications. It enables you to build fast and user-friendly static websites, as well as web applications using Reactjs. Using OpenTelemetry Nextjs libraries, you can set up end-to-end tracing for your Nextjs applications. Nextjs has its own monitoring feature, but it is only limited to measuring the metrics like core web vitals and real-time analytics of the application.

Let’s explore what OpenTelemetry is and isn’t. Here is what OpenTelemetry says about the project…

Let me set the record straight before anyone accuses me of bias or not being an OpenTelemetry supporter. Cribl loves OpenTelemetry! We’ve written lots of blogs about It; we have vendor-specific OpenTelemetry Destinations (with more to come!), and we support automatic batch parsing for easier data manipulation and re-batching for network transport efficiency of logs, metrics, and traces.
