Even though there was a py36 test enabled in the gate, the tox.ini configuration was not actually invoking the unit tests. This change sets up the environment to allow tests to run. As a result, a number of Python3 errors are uncovered and fixed. Notably: Python 3 does not have contextlib.nested, so reformatting using , file() is not in Python 3, so use io.open() instead Use six.assertCountEqual(self, in tests safe_decode: subprocess.check_output returns in byte encoding, while default text type str. safe_decode does the right thing by making sure string are not bytes in python2 and python3 No ascci encoding: python3 defaults to UTF-8 encoding, which is merely an extension to ascii (default for python2). test_json_plugin.py: the file being opened in binary(wb) mode so python is expecting the string in bytes. Some of the refactoring should be revisited after we drop Python 2 support. Change-Id: I62b46a2509c39201ca015ca7c269b2ea70c376c8 Story: 2005047 Task: 29547

Introduction
The Monasca Agent is a modern Python monitoring agent for gathering metrics and sending them to the Monasca API. The Agent supports collecting metrics from a variety of sources as follows:
- System metrics such as cpu and memory utilization.
- Nagios plugins. The Monasca Agent can run Nagios plugins and send the status code returned by the plugin as a metric to the Monasca API.
- Statsd. The Monasca Agent supports an integrated Statsd daemon which can be used by applications via a statsd client library.
- Host alive. The Monasca Agent can perform active checks on a host to determine if it is alive using ping (ICMP) or SSH.
- Process checks. The Monasca Agent can check a process and return several metrics on the process such as a number of instances, memory, io and threads.
- Http Endpoint checks. The Monasca Agent can perform active checks on http endpoints by sending an HTTP request to an API.
- Service checks. The Agent can check services such as MySQL, RabbitMQ, and many more.
- OpenStack metrics. The agent can perform checks on OpenStack processes.
- The Agent can automatically detect and setup checks on certain processes and resources.
The Agent is extensible through the configuration of additional plugins, written in Python.
