Hey,
I want to track my frontend javascript errors, I am not totally satisfied with my current setup. What services are you using to track js errors? I like the idea of owning my data, so I would prefer solutions that can be hosted on premise or are open-source.
We are using Sentry (https://sentry.io/). Easy to install. Good overview of incidents.
Oh wow, didn't know that sentry was open-source, I somehow managed to miss this :D
Haven't use it, but I found https://snowplowanalytics.com/ in the past and looked interesting.
