As <a href="https://developers.google.com/web/updates/2018/09/reportingapi" rel="nofollow ugc">noted on the Google Developers blog</a>:
<blockquote>
The Reporting API defines a new HTTP header, <code>Report-To</code>, that gives web developers a way to specify server endpoints for the browser to send warnings and errors to. Browser-generated warnings like CSP violations, Feature Policy violations, deprecations, browser interventions, and network errors are some of the things that can be collected using the Reporting API.
</blockquote>
This plugin provides a storage mechanism and endpoint for browser reports according to the Reporting API spec in WordPress, as well as an admin interface for browsing these reports. It also provides an API for sending the <code>Report-To</code> response headers.
As the Reporting API specification is still evolving and at an early stage, the plugin reflects that and is currently an experimental prototype, to demonstrate how Reporting API can be used in WordPress.
<h4>Did you know?</h4>
There is also a new specification called Feature Policy which will integrate with the Reporting API specification. There is a <a href="https://wordpress.org/plugins/feature-policy/" rel="ugc">WordPress plugin for Feature Policy</a> as well.

This plugin sends you an email notification whenever a fatal error (or other error level, configurably) is detected on your site.
Unlike traditional uptime monitoring services, which will only notify you if your entire site is down, this plugin can notify you when an error is detected on any page or process on your site.
Automatic plugin and theme updates often introduce problems that you aren’t aware of until they’re reported by your visitors. Fatal Error Notify lets you address these issues as they occur and before they cause significant problems.

Fatal Error Notify

Great plugin

Thiss plugin is useful but won´t work on certain installs, although this could easily be fixed with some enhancements.

useful plugin but could be improved

I used Fatal Error Notify on a site that kept crashing and I couldn't find out what was going wrong.  The plugin emails the PHP error message and that helped me track down the issue. 

Can be a real lifesaver

Just came here to say that this is an amazing plugin and it's extremely helpful during troubleshooting.

keep up the good work!
