Need help setting up a monitoring system? Here’s a complete, easy to deploy, dockerised monitoring system for a local development environment with email alerts.

The open source software Prometheus is an effective and reliable way of monitoring a software service like a web application. It will monitor your service and notify you when it goes down. In addition Prometheus also collects numerous kinds of metric data from the target for diagnostics and display purposes. Presented below is a convenient and reliable docker compose script with a complete ensemble of components useful for running a complete Prometheus monitoring system in a local environment for evaluation and integration testing purposes. Be operational with one docker command. Included in the compose design are containers for Prometheus, Prometheus Alertmanager, Mailhog (a test SMTP server) and some Python code acting as a target to be continuously monitored. Prometheus is also able to monitor code developed in Node, Java, Ruby, Go, Rust, C++, C# and PHP to name a few [3]. Easily update the compose script to incorporate your particular service to be monitored.

In this blog, I will be explaining the path that I’m following in my DevOps journey.
