health-checks

A Simple Health Check Tool

Background

CloudFlare provides Health Checks but you have to be on a paid plan. Vultr provides Free-Tier VPS (512 MB, 1 Core, 10 GB SSD, 2 TB Bandwidth).

This lightweight VPS does not have much RAM - so it cannot run heavy applications, but this (health check) tool should be a good use case for it.

Most code at the "init commit" is done by ChatGPT. Thank you!

How to Run?

No docker - as you probably can't run docker on it. You can either run it in screen or pm2 so that it will stay in background.

Config.json

Change config.json.sample to config.json and modify the content necessary - which should be pretty straightforward.

Run Health-Checks

Simply Run node health-checks.js,

Example:

In case of failures:

You should get an email, if configured correctedly.

TODO:

Configure a max email per period (PR welcome)
