Tracing

The latest News and Information on Distributed Tracing and related technologies.

Distributed Tracing 101

The boom of digital commerce is making all businesses take a closer look at how they deliver great customer experiences. To stay competitive, businesses today are using cloud-native architectures, because the cloud-native applications they produce deploy quickly and better support the continuous improvement cycles of agile methodology. Behind the practicality of keeping online customers happy are distributed cloud environments that business applications use for each customer interaction.

Monitoring GraphQL APIs with OpenTelemetry

GraphQL is a query language for APIs developed by Facebook in 2012. It was then open-sourced in 2015. GraphQL enables frontend developers or consumers of APIs to request the exact data that they need, with no over-fetching or under-fetching. In this article, we will learn how to monitor GraphQL APIs with the open-source APM tool, SigNoz. GraphQL has become a popular alternative to REST because of its ease of use. It enables developers to pull data from multiple data sources in a single API call.

Unified Serverless Observability With OpenTelemetry and StackState v4.6

StackState has always believed in the importance of open source and open standards, and we’ve demonstrated our commitment through ongoing support of open technologies. From the beginning, StackState supported StatsD and OpenMetrics. Even our agent is open source, designed to help organizations easily onboard our platform and to give them an extensible open way to observe their services. StackState is now proud to announce our next big open source step.

A tale of dependencies

One Friday afternoon we got a Slack message from one of our early customers, letting us know that there was an issue with updating our SDK. Apparently, our SDK introduced a new dependency to the code that their team wasn’t able to meet: graphql@16.0.1. This made it impossible for the customer to upgrade to a newer version of our SDK and became a blocker for them.

Why is Distributed Tracing in Microservices needed?

Microservices architecture allows technology companies to build application services around business capabilities. It enables rapid development and also boosts developer productivity. But it also introduces complexity. Troubleshooting and operating an internet-scale application based on microservices is hard. And that’s where distributed tracing comes into the picture. Traditional monolithic application architecture is easy to develop, deploy and monitor.

startSpan vs. startActiveSpan

TL;DR: startSpan is easier and measures a duration. Use it if your work won’t create any subspans. startActiveSpan requires that you pass a callback for the work in the span, and then any spans created during that work will be children of this active span. I’m instrumenting a Node.js app with OpenTelemetry, and adding some custom instrumentation. For this important activity that I’m doing (let’s call it “retrieve number”), I’m creating a custom span.

Real-time distributed tracing for .NET Lambda functions

In 2020 we released distributed tracing for AWS Lambda functions written in Python, Node.js, and Ruby, providing you with health and performance insights across your serverless applications. Since then, we’ve expanded our support to additional Lambda runtimes such as Java and Go, and are pleased to announce that real-time distributed tracing is now also available for.NET Lambda functions.

APM is Legacy. Distributed Tracing is Designed for Modern Teams

Some background. Having implemented at least 20 or more APM systems in production as an end-user at various companies, and both deployed and managed countless monitoring tools outside APM, I understand the role of the practitioner. Later on, I shifted to Gartner and led the APM Magic Quadrant for four years, finally spending another four years at AppDynamics (operating under Cisco after two years).
