In this article, we’ll cover the introduction of distributed tracing in Betfair. First, we outline our problems with monitoring and logs, and explain why we think tracing is important. Then we detail the steps we took to enable tracing the bet placement in our platform. If you are looking for an open source implementation of a distributed tracing system, we propose you to check out https://www.jaegertracing.io/ . Jaeger is also our choice here in Betfair. Yuri Shkuro has written a great book on the subject.
