We use Datadog and Sentry because their mechanism of interaction and retention are different - if Datadog changed their process to be closer to the way Sentry aggregates errors over time I can see us never needing Sentry again.
I had a chuckle when I looked at the source code and could not find a Dockerfile in there. I want to kick the tires on it and the easiest way would be to run it as a Docker container against an existing file and alas, I cannot.
