I have been test-driving this on a single page, and it monitors plugins and errors without causing any issues. In that sense, it is very helpful to keep a bird's-eye view over sites you are running that are critical if they go down or update create PHP related errors that only show up in error or warnings.

I haven't used it in an ongoing development and am not sure if that makes sense as the errors would get relayed, but I am willing to give it a try.

Things that could be improved:
- I like the reporting, but it needs to be white labeled if I want to forward it to a client.
- Reports and the design of them is not customizable. Like allowing to include the "warnings" settings and keeping them as slick as the tool. They use images in the report (not a fan of stock images)
- Reports can't be auto-generated in a given interval, this would be really great.
- Reports cannot be export to email or PDF
- Notifications are limited to mail and slack. A generic webhook interface or Zapier would be also very welcome.

The plugin is useful as is, but could be improved.

A solid 4/5 Tacos.
