Practical introduction to OpenTelemetry tracing

Tracking a request’s flow across different components in distributed systems is essential. With the rise of microservices, their importance has risen to critical levels. Some proprietary tools for tracking have been used already: Jaeger and Zipkin naturally come to mind.

Observability is built on three pillars: logging, metrics, and tracing. OpenTelemetry is a joint effort to bring an open standard to them. Jaeger and Zipkin joined the effort so that they are now OpenTelemetry compatible.

Solving an Internal Real-World SRE Issue with Eclipse Trace Compass

Matthew Khouzam (Ericsson AB)

This talk will guide you on the steps taken to solve a real SRE (Site Reliability Engineering) issue we faced. This problem caused a slowdown for several thousand developers, but no service loss. We will show how good logging/tracing strategies and pre-emptive log post-mortems can save a company hundreds of hours.

What's cooking in the TraceCompass.cloud project?

Bernd Hufmann (Ericsson AB)

Traditionally, trace analysis and visualization tools are strongly coupled with the format of the trace files of the traced system. These available tools in the industry are focused on specific trace formats and specialized use cases for their systems.

Tracing microservices using MicroProfile Telemetry

Emily Jiang (IBM)

Do you know the new tracing standard? OpenTelemetry (https://opentelemetry.io), the merge OpenTracing and OpenSensus, is the answer. MicroProfile adopts OpenTelemetry Tracing and enables microservices to trace the invocations even easier. Come to this session to learn about how to use the new specification MicroProfile Telemetry to trace your microservices.

Establishing a Theiacracy, Eclipse Trace Compass’ migration towards Theia

Bernd Hufmann (Ericsson AB)

This talk will show how a monolithic application is being migrated to a distributed application leveraging Eclipse Theia. We will review the migration steps and how to preserve investments made by maximizing the reuse of domain specific logic.

Anthology of solved problems: finding the root cause of your performance and stability issues

Matthew Khouzam (Ericsson AB)

This talk is a collection of smaller incidents showing why configuration is often key. There will be examples of critical path analysis, when to parallelize, when there is too much parallelization, timeout analysis, deadlocks, when to instrument more and other common pattern recognition.

Put on your X-ray glasses - it’s time to trace

Matthew Khouzam (Ericsson AB)

Linus’s law states “Given enough eyeballs, all bugs are shallow.” This is very true, however, if a problem is obscured, the more eyes won’t help until they can see through the blocker. This talk addresses tracing, how and when to use it, and how it can see through these issues. It is re-enforced with a real-world example of how tracing solved a performance issue in Trace Compass. We will discuss tracing, and how it plays in a world where profiling and debugging already exist.

Concerted visualization of converging technologies

Thomas Haber (toem GmbH)

Today's development of embedded systems/IoTs and SOCs (Systems on Chip) faces the problem of a rapidly growing complexity.

Due to the decentralised nature of the development (multiple cores on external boards, specific hardware components, external communication interfaces, simulated components,...) it is difficult to visualize, debug and understand the behavior.

The information to be processed differs in nature:

EASEly extending Eclipse Trace Compass

Bernd Hufmann (Ericsson AB)

Genevieve Bastien (Ecole Polytechnique de Montreal)

Trace Compass is a powerful tool to solve performance and reliability issues by reading and analyzing traces and logs of a system. It has been always an integral part of the Trace Compass project to allow users to extend Trace Compass for custom trace and log formats, custom analysis and views using Java plug-in extensions or by loading user defined XML definitions on-the-fly.

Many users, however, are more comfortable with writing scripts to automate their tasks, and hence it seemed to be a natural fit to use scripting for trace analysis. Eclipse EASE enables users to quickly extend Trace Compass by writing scripts in JavaScript, Python or Ruby.

Using Theia to take trace analysis and visualization to the next level

Bernd Hufmann (Ericsson AB)

Analyzing and visualizing traces and logs of a system is a powerful and proven trouble-shooting technique to solve performance and reliability issues. Trace Compass is an open source trace visualizer that handles large traces of a single application, single computer or a distributed system. The Trace Compass project is currently on a journey towards a cloud-based trace analysis and visualization solution using Eclipse Theia.
