> but they seem clear that there's both a logging and metrics (apm) side to their product.
yes they have those two sides. what they do not have is an error tracking side; something like sentry[1]. errorship exists to bring the error tracking side into datadog.
The logging side of datadog is like splunk or elasticsearch, and their APM side is like newrelic. errorship is bringing the error tracking side.
some of the analogies may not apply 100%, but I hope I'm making sense.
