In this example, we are using Centos7, journalctl and systemctl so that we can monitor logs from DC/OS instances (masters, agents and public agents). It is useful for anyone using systemd, journald in an AWS EC2 enviroment that wants logging. The nice thing about Amazon CloudWatch is that it integrates well with Amazon EMR and Amazon Elasticsearch. (For more background on this subject see this article which covers using CloudFormation, Packr, etc. for Immutable Infrastructure to build DC/OS and deploy it to Amazon Web Services.)

We will install journald-cloudwatch-logs. We are going to setup a daemon into systemd that forwards logs to Amazon CloudWatch log streams.

	To install virtualenv via pip
	$ pip3 install virtualenv

	Note that virtualenv installs to the python3 directory. For me it's:
	$ /usr/local/share/python3/virtualenv

	Create a virtualenvs directory to store all virtual environments
	$ mkdir somewhere/virtualenvs

	Make a new virtual environment with no packages

	from collections import namedtuple
	def convert(dictionary):
	return namedtuple('GenericDict', dictionary.keys())(**dictionary)

	"""
	>>> d = dictionary(a=1, b='b', c=[3])
	>>> named = convert(d)
	>>> named.a == d.a
	True
	>>> named.b == d.b
