AppSignal

We wanted to have a tool that has both APM and error monitoring stuff included in one.

I preferred to go to New Relic as the free version offers 100gb storage but have seen some "not good" comments about it compared to Datadog.

My teammates suggested AppSignal.

So which one should be a good option to give a try?

Tech Stach -> Ruby on Rails, Rails-react, Amazon EC2 machine.

Coming from a Ruby background, we've been users of New Relic for quite some time. When we adopted Elixir, the New Relic integration was young and missing essential features, so we gave AppSignal a try. It worked for quite some time, we even implemented a :telemetry reporter for AppSignal . But it was difficult to correlate data in two monitoring solutions, New Relic was undergoing a UI overhaul which made it difficult to use, and AppSignal was missing the flexibility we needed. We had some fans of Datadog, so we gave it a try and it worked out perfectly. Datadog works great with Ruby , Elixir , JavaScript , and has powerful features our engineers love to use (notebooks, dashboards, very flexible alerting). Cherry on top - thanks to the Datadog Terraform provider everything is written as code, allowing us to collaborate on our Datadog setup.
