Monitoring a containerized application

Monitoring a containerized application is crucial for understanding the application’s performance, resource usage, and potential bottlenecks. This section will detail a step-by-step process for monitoring a containerized application using Prometheus, Grafana, and cAdvisor.

Step 1 – setting up Prometheus

Follow the instructions from the previous section to set up Prometheus and cAdvisor to collect and scrape metrics from containers running on Docker Desktop.

Step 2 – instrumenting your application with Prometheus metrics

To monitor a containerized application, you need to instrument the application with Prometheus metrics. This involves adding Prometheus client libraries to your application code and exposing metrics on an HTTP endpoint, usually /metrics.

Choose the appropriate Prometheus client library for your application’s programming language from the official list: https://prometheus.io/docs/instrumenting...
