errorship is not using the datadog eventstream to send all logs to it. Rather, errorship just sends exceptions, their stack traces(and a few other metadata like hostname) to the eventstream.

The datadog documentation[1] says; "An event represents any record of activity noteworthy for engineers"[1]. We certainly believe that exceptions that occur in engineer's applications are noteworthy activities and as such belong to the eventstream.
