supermann 1.2.0

=========
Supermann
=========

Supermann monitors processes running under `Supervisor <http://supervisord.org/>`_ and sends metrics to `Riemann <http://riemann.io/>`_.

Requirements
------------

* `argparse <https://pypi-hypernode.com/pypi/argparse>`_
* `protobuf <https://pypi-hypernode.com/pypi/protobuf>`_
* `psutil <https://pypi-hypernode.com/pypi/psutil>`_
* `supervisor <https://pypi-hypernode.com/pypi/supervisor>`_

The psutil package uses C extensions, and installing the package from source or
with a python package manager (such as ``pip``) will require build tools.
Alternatively, it can be installed from your distribution's repositories
(``python-psutil`` on Debian and CentOS).

Supermann is developed and tested on Python 2.6. There are no plans to release
it for Python 3, as Google's ``protobuf`` library is only compatible with
Python 2. However, the code is written to run on Python 2.6, 2.7 and 3.

Configuration
-------------

Supermann runs as a Supervisor event listener::

[eventlistener:supermann]
command=supermann localhost 5555
events=PROCESS_STATE,TICK_5
autorestart=true

Run `supermann --help` for usage information.

Notes
-----

The Protocol buffer definition can be rebuilt using the most recent version::

wget https://github.com/aphyr/riemann-java-client/blob/master/src/main/proto/riemann/proto.proto
protoc --python_out=supermann/riemann/ riemann.proto

If supermann is used as a library, you will need to ensure that the log messages
Supermann emits are handled. This can be done by either configuring the python
logging module, calling ``supermann.command.configure_logging``, or adding a
null handler::

import logging

class NullHandler(logging.Handler):
def emit(self, record):
pass

logging.getLogger('supermann').addHandler(NullHandler())

Supermann should never send events with a nil host, and will always use the current hostname as the default host for events.
