Tool to monitor name resolutions and websites

See the https://github.com/szabgab/try-monitor/ or the https://github.com/szabgab/my-monitor repositories for an examples.

Create a configuration YAML file like this:

sites/code-maven.com.yaml

sites:
  # To check the mx DNS resolving of a domain use the `mx` key.
  - mx: code-maven.com
    ips:
      - mx1.forwardemail.net.
      - mx2.forwardemail.net.
  # To check the DNS resolving of a hostname use the `host` key and either specify the list of expected IP addresses ...
  - host: academy.code-maven.com
    ips:
      - 173.255.196.65
  # ... or use the word `github` if your host is hosted on github pages.
  - host: code-maven.com
    ips: github
  # To check the content of a web site use the `url` key.
  - url: https://code-maven.com/
    status_code: 200
    html_contains: "<title>Code Maven - for people who code</title>"
  # To check the redirection of a web site use the `url` key.
  - url: http://code-maven.com/
    status_code: 301
    headers:
       Location: https://code-maven.com/

Create a GitHub Workflow file:

This will run the workflow once an hour at the 42nd minute of the hour.
This will use the version that was tagged as v1.04 This makes it safe and boring as the action does not change beneath your workflow.
Instead of v1.04 you should probably use the most recent tag or you can live on the edge and use main instead.
You either list the specific config files or you can use wild-cards. In the example below you can see both.

name: CI
on:
  push:
  pull_request:
  schedule:
   - cron: '42 * * * *'
  workflow_dispatch:
jobs:
  build-in-container:
    runs-on: ubuntu-latest
    container:
      image: python:3.14
    name: Run
    steps:
      - name: Checkout
        uses: actions/checkout@v6
      # Pass the name of the individual config files
      - uses: szabgab/monitor@v1.04
        with:
          config: sites/code-maven.com.yaml sites/szabgab.com.yaml
      # Pass wild-card should also work
      - uses: szabgab/monitor@v1.04
        with:
          config: sites/*.yaml
