Uptime Checker Extensions

Updog doesn't do any monitoring by itself. Instead, extensions are used to check the status of whatever thing, send alerts, and log stuff. Updog just chains them together.

Example extension: askiiart/updog-checker_template

Folder layout

Extensions need to be put in the ./extensions/checkers folder, and the name of the file must match the name of the folder.
