Not brand new but pretty new and relevant for a lot of people here who don't have, pay for, or spend time dealing with open source solutions they need to manage for monitoring their servers and real time/archived log data for their servers and applications. Also this will get you the ability to set up custom alerting on your websites if they go down (they will ping every minute), also for services and CPU/RAM. You can have alerts via SMS, email, etc.
Google Cloud Platform has two awesome solutions both in Beta so they are 100% free for the time being, these work for anything hosted on AWS (Amazon Web Services), GCE (Google Compute Engine) or GAE (Google App Engine).
Google Stackdriver Logging - https://cloud.google.com/logging/
Google Stackdriver Monitoring - https://cloud.google.com/monitoring/
Logging uses a modified version of Fluentd to deliver the logs in real time to their logging platform. Also they support live tail of your logs which some places you have to pay big money for, Loggly charges $350+ monthly to get this option. Never have to use another console window and manually tail your logs again!
For setting up the monitoring agent you can do it on GCE or AWS in 5 minutes max for the quickstart. Also they have a full API supporting over 900 metrics you can use.
No reasons anymore to not have monitoring and logging for your servers, did I mention the free part?
Also for interested parties I have a role that works 100% with Trellis (I know because I'm using it) to automatically set up every important service that has a log on your server, PHP, Nginx, syslog, etc and every website you provision with Trellis it automatically adds the error and access logs. Every service and every website log is individually tagged so you can search for and live tail easily for anything you want to see by themselves or as a whole.
If there is interest let me know and I'll add comments to my code and instructions on how to add it to Trellis easily and I'll put it on Github.
