A simple host health checking tool. To get started, clone the repository and build for your required system. If you're on Windows, you can use the build.ps1 PowerShell script to cross-compile for Windows 64bit, Linux 64bit, RaspberryPi (ARM) 32bit (suitable for most RaspberryPi's) and MacOS 64bit.

To run, you will need two files, config.json and urls.json.

The config.json file contains the PushOver User key and API key, e.g.:

{
  "userkey": "<my-user-key>",
  "apikey": "<my-api-key>",
  "interval": 3,
  "client_timeout": 30
}

An interval of 3 means the app checks the URLs every 3 minutes. The client timeout is supplied in seconds. It is the time a single host is allowed to take to send a response. The urls.json file contains a list of URLs to check, e.g.:

[
  "https://github.com",
  "http://127.0.0.1:4001/ping"
]

When requests to the PushOver API fail, a log entry will be written to the response_errors.log file.
