Metrics for Observability are so Cool #code #programming #tips

Monitoring application performance is crucial, and metrics are a powerful way to track specific parts of your application over time. In this tutorial, we'll cover the three common types of metrics: Counters, Gauges, and Histograms. We'll show you how to set up metrics using OpenTelemetry libraries and visualize them with Prometheus.

By installing the necessary OpenTelemetry packages and setting up a simple counter to track HTTP requests, you'll be able to monitor your application's performance effectively. Finally, we'll use Docker to set up Prometheus for visualizing and analyzing these metrics. Check out the full tutorial to learn the best way to monitor your application's performance!
