RailsConf 2019 - Troubleshoot Your RoR Microservices with Distributed Tracing by Yoshinori Kawasaki
In microservices architecture, it is often challenging to understand interaction and dependencies between individual components involved in an end-user request. Distributed tracing is a technique to improve observability of such microservices behaviors and to help understand performance bottlenecks, to investigate cascaded failures, or in general, to troubleshoot.
In this talk, I will show how we’ve implemented distributed tracing in Rails apps using OpenCensus, a set of vendor-neutral libraries to collect and export metrics and traces, and real world examples from our system that consists of about 100 microservices built with Ruby, Go, Python, Node and Rust. I will also discuss other methodologies to improve “observability” of Rails apps in microservices and future direction.
If you feel pain in troubleshooting microservices of Rails, you’ll love distributed tracing.
