[Lecture Update] Monitoring Claude Code Usage with OpenTelemetry
Hello! The "Mastering Claude Code" course has been updated with the Advanced Feedback section on Telemetry Monitoring!
This section covers the essentials for transitioning Claude Code from a personal tool to one used by a team or organization. This falls under the domain of observability, which involves transforming the logs streaming on your personal screen into queryable data for the organization.

This update includes the following three lectures.
OTel Concepts and Ecosystem
Enable Claude Code Telemetry
Collection Stack Hands-on - Setting Up otel-collector, Prometheus, Grafana, and Loki with Docker Compose

The final lecture includes the hands-on materials. It contains the docker-compose.yml and configuration files for the collector, Prometheus, Loki, and Grafana, so all four containers spin up with just a single command. You can use it to verify the overall setup on your local machine before integrating it into your company's environment. All you need is Docker Desktop running.
Give it a try, and when adopting it for your team, use it to help establish criteria for how much data to collect :)
Then I'll be cheering you on in your learning journey!
I'll be back next time with more useful updates.
Thank you.
