One of the major strengths of Simon, my website and server monitoring tool, is the flexibility it offers through the ability to write custom scripts in many scripting languages. Simon is plenty useful with the built-in services, filters, and notifiers, but the ability for customers to enhance it themselves makes it even better.

There are several script-based services, filters, and notifiers built in to the app, and others can be downloaded from the Simon Extras page.

One such example is the Show & Screenshot notifier script (click that link to download it). To install it, go to the Notifiers page in Simon, add a new notifier, choose Script for the notifier kind, click the Open Script… button, and choose the downloaded script.

This script simply opens the page in the default web browser, waits a few seconds for the page to render, then takes a screenshot of it. By default it’ll wait 10 seconds, and save to the Desktop, but you can customize those values; enter the path of a folder to save them to (the folder must already exist). Also specify how long to wait before performing the screenshot, in seconds:

And of course to use the notifier, specify it in the Notifiers page of a test:

Note that when this notifier is first used, macOS will ask for permission to capture the screen; until you grant that, it’ll capture an empty desktop.

Check out the Simon Extras page for other scripts. And if you create a useful script for Simon, please share it with others!
