As a developer, getting metrics from your application onto a Prometheus graph can seem daunting. We’ll look at analyzing your service to find the most useful places to add metrics, how to add that instrumentation, getting it exposed and scraped, and then basic queries to use those metrics on graphs. Check out another article of mine for general reference on instrumenting, this one on Prometheus metrics, or this comparison on instrumentation alternatives.

In this tutorial, we will be using Heroku to deploy our Node.js application through CircleCI using Docker. We will set up Heroku Continuous Integration and Deployment (CI/CD) pipelines using Git as a single source of truth. Containerization allows developers to create and deploy applications faster with a wide range of other benefits like increased security, efficiency, agility to integrate with DevOps pipelines, portability, and scalability.

OpenTelemetry is an instrumentation standard for application monitoring - both for monitoring metrics & distributed tracing. In this blog, we take you through a hands on guide on how to run this on Kubernetes.
