Presented at API Days Australia LIVE - 16 Sep 2021
Everyone is building distributed systems these days. Some better than others. One thing the teams building and running distributed systems well have in common is they have very good observability of the components and services. Conversely, the teams that don't have good observability struggle when things go wrong in a distributed system because it's often terribly time consuming to put the pieces together to analyse the crime scene. The logs might sit in disparate log aggregation systems and even when in one place, leave you with having to do the hard work to correlate and visualize the system workflows yourself.
OpenTelemetry is an observability framework for cloud-native software which aims to solve some of these issues by having a common set of definitions of concepts around observability and exposing them to the tool of your choice.
In this talk, I examine how to propagate your tracing context across process boundaries and visualize the flow of requests through your distributed services (Microservices/Serverless/Other) easily using tools like Zipkin and Jaeger. We will see how to use already instrumented libraries and also how to propagate the trace information yourself. At the end of this talk you will know how to easily trace and observe distributed components of the systems you build.
