Open Source Observability Stack Essentials
I’m excited to share that my newest course is now live on Coursera: Open Source Observability Stack Essentials.
This course is built for software engineers, SREs, and platform engineers who want a practical, hands-on way to learn the foundations of modern observability using the open-source tools that matter most: Prometheus, Grafana, and OpenTelemetry.
In just a few hours, you’ll go from concepts to practice:
- understanding metrics, logs, and traces
- deploying a minimal local observability stack
- instrumenting an app with OpenTelemetry
- building a Grafana dashboard for requests, errors, and latency
- creating alerts that are actually useful in real environments
I designed this course to be practical, not theoretical. By the end, learners will have working configs, starter queries, and a clearer path toward production-ready observability, including topics like SLOs, burn rate alerts, retention, and exporter strategy.
Observability is no longer optional in cloud-native systems. Modern applications rarely fail loudly — they fail through latency, partial degradation, and noisy dependencies. My goal with this course is to help learners build the skills to detect, understand, and troubleshoot those issues with confidence.
Thanks to everyone who has supported my learning journey so far through books, courses, and the open-source community. I’m proud to keep contributing content that helps engineers build stronger systems.
