Advise me on tracing/logging multiple dockerized services written in JavaScript

I have multiple production services written in JavaScript that interact with one another and are experiencing some intermittent issues. Currently for troubleshooting and monitoring I need to review logs in multiple locations - Docker Cloud and [login to view URL] - which only retain a few hundred lines of logs making it hard to get an overview of patterns, past issues, etc. What I'm looking for in this project is advice on tracing/logging best practices from JavaScript applications and docker containers as well as pros and cons of various log management platforms (eg, Logstash, Papertrail) for collection and analysis of logs and metrics.
