Sending requests to specific endpoints

A unique take on application monitoring

Oh Dear will not run any code inside your application or server. Instead, you should perform the checks yourself. Oh Dear will send an HTTP request to your application to a specific endpoint. Your application should respond with JSON containing the result of health checks.

While this may seem like a lot of work, the big advantages are that you don't need to install any kind of agent on your server. You can perform any health check that you want.

Receive smart and instant alerts

when performance drops

We believe in two kinds of important alerts when it comes to performance: hard limits and sudden changes.

Per website, you're able to define a hard performance limit that should not be crossed. Once we detect the website is consistently crossing that threshold, we'll let you know.

It's very powerful to know when your site suddenly becomes faster or slower. It could be due to increased load on your servers, it could be a faulty new deploy that only renders half the page, ... whatever it may be, you'll find our sudden change alerts worthy of your attention.
