We use OpenTelemetry extensively at Torq. In fact we are tracing 100% of our traffic. We started building the product with the idea in mind that we dislike logs and want to use them as little as possible.
Since then we have grown to 30 engineers and everyone is in love with OpenTelemetry. We use it during development and to debug issues in production. We have automations built around it, special middleware we developed for our internal libraries to report traces (orm, pubsub etc).
In this talk I will present OpenTelemetry, its core features and some cool features that are unique to GCP for tracing SQL queries.
We will build a simple microservice application that uses tracing with database, pubsub, grpc and demonstrate how we work with it to analyze bugs and performance issues.
I will discuss the various options for viewing the traces.
This can be either a talk or a tutorial.
I am giving this talk next month at Google so I will have some slides to share.
In the previous GopherCon people expressed interest in our usage of OpenTelemetry, so I think it will be a cool lecture.
