You can't fix what you can't see: telemetry for Rust APIs
Workshop run by Mainmatter
Your Rust application has finally been deployed to production! Nice! But is it working? This workshop will introduce you to a comprehensive toolkit to detect, troubleshoot and resolve issues in your Rust APIs.
All workshop participants will receive a free 3 month CLion license valid for personal use from our friends at JetBrains.
This workshop is designed for developers who are operating Rust services in production-like environments, or are preparing to do so.
Structured logging (tracing)
An introduction to the
tracinginstrumentation library, covering both how to instrument your code (capturing fields, log levels, macros) and how to process the resulting telemetry data in your application (subscriber configuration, logging levels, log filtering).
We will cover Rust’s
Errortrait, with a focus on the information that can be retrieved and recorded in your logs; we will also spend some time on logging patterns (e.g. when should an error be logged?) and relevant libraries for error handling (anyhow/thiserror).
You should always manage to capture details about what went wrong, even if it’s due to an uncaught panic rather than an error. We will review panic hooks and integrate them in our
Metrics, both for application and runtime (tokio-metrics)
Structured logs are important, but they don’t tell the full story. We will look at how to capture metric data using the
metricslibrary, as a tool for designing alarms as well troubleshooting faulty behaviour. We will spend some time on
tokio-metricsand how to interpret the data it shows with respect to your
We will send a detailed list of instructions for preparation. This information will be provided closer to the workshop date.
