In my search for a comprehensive logging solution for MuzHack that works in a Dockerized environment, more specifically Tutum, I came across Papertrail.

Papertrail is a fairly simple Web application for log aggregation, that receives log data over the Internet through the syslog protocol. As a registered user of Papertrail, you receive a syslog address that serves as your logging destination. Multiple sources (or "systems" as per Papertrail lingo) can use the same logging destination, as Papertrail will automatically discern between them (based on their hostnames). In my case, this corresponds to my staging and production deployments.
