Telemetry/observability/monitoring setup #60
Description
Right now we don't have any kind of observability on the application, sub processes (stacks) and errors .
A first quick win would be to add Sentry to the application and some Logger.error and Logger.info to critical paths on the application if they don't exist already. This would be relatively low hanging fruit and would have a great impact.
We could also explore enabling, Phoenix Dashboard in production given that it provides some cool stuff out of the box (information about the system,metrics based on :telemetry events with real-time charts, see everything that was logged for requests, see, filter, and search processes in the application), it's already on the app, we would only need to setup a production account, and it's easily extensible.
