Introduction

I use Sentry when I want to monitor my application. You can find it on https://sentry.io/.

It has a support for wide variety of programming languages like JavaScript, Python, Node, .Net (including Core), Java etc. It also has built in support for number of frameworks, for example Angular/React on frontend, Flask/Express or Koa on the backend.

Here you can see the dashboard:
