Fixed bug where the argument signature for the invalidate event handler
incorrectly formed, preventing invalidation events from being intercepted
correctly. Pull request courtesy Dmitry Kulagin.

The "pid" value that is collected by the client plugin and passed to the
aggregator in order to disambiguate separate processes is now augmented
by a six character random hex string, so that a single host that may have
the same pid repeated, such as when process namespaces or containers are
used, sends correct statistics for the same program name configuration.

:tags: feature
Made large improvements to the connmon display, including a help screen,
switching between program / host stats, and new stats views. Overall, as
connmon is attempting to collect from collectd servers which may also be in
a network of servers, the "interval" by which messages are received may be
long, ten seconds by default and much more. To allow a console view to be
meaningful, new stats are added that illustrate how many connects /
checkouts have occurred over the last "interval". That way, even though
you might never see the current number of "checkouts" go above zero, you
can at least see that the last ten second interval had 25 checkouts occur.
The checkouts per second number can be derived from other values shown in
the display.

Fixed bug where the command line options to connmon didn't work due to
incorrect argument signature for the main() function.

The "connmon" tool can now display stats for SQLAlchemy stats that are sent
to a collectd server via the "network" plugin or through any other means.
Previously, the connmon tool could only display stats for messages that
were sent to a the collectd server by the SQLAlchemy-collectd plugin
itself.
The server side configuration for "connmon" is now separate from that of
the SQLAlchemy-collectd plugin, and the two plugins can run independently
of each other. This allows for a configuration where many hosts send
SQLAlchemy-collectd messages to local collectd servers for aggregation, and
those servers then pass their messages onto another collectd server, where
the "connmon" tool can provide a view inside the current stats.
In order to achieve this, major refactoring such that the internals now
deal with data in terms of a structure which mirrors the collectd-python
"Values" object is in place, along with a rearchitecture of the connmon
tool such that it now consumes collectd "Values" objects from a particular
collectd server regardless of how those "Values" arrived in that server.

:tags: bug, setup
:tickets: 6
Reorganized the tox.ini script so that a plain run of ``tox`` will run
against a single interpreter. The "python setup.py test" command is
no longer supported by setuptools and now emits a message that ``tox``
should be used.
.. change::
:tags: bug, protocol
:tickets: 4
Added additional resiliency to the network protocol, such that if an
entirely garbled message is sent to the server (such as making a test
connection with nc and sending random characters), the protocol parser
reports that the message is invalid rather than producing KeyError due to
not being able to locate a message type.
.. change::
:tags: bug
:tickets: 5
Added error resiliency to the server and client threads, so that exceptions
which occur are logged and the thread continues to run. Additionally, fixed
the logging handler in the server plugin so that stack traces for errors
are added to the output.

:tags: bug, config
:tickets: 3
Fixed bug where the port number included in the SQLAlchemy URL with the
collectd_port query string value would not be coerced into an integer,
failing when it is passed to the socket send operation.

:version: 0.0.4

:tags: feature
The connmon real-time console UX, first developed as its own client/server
project, has now been migrated to SQLAlchemy-collectd, consuming collectd
events over UDP from the collectd server itself which runs the
SQLAlchemy-collectd plugin. This greatly reduces the footprint and
complexity of the previous connmon implementation and allows applications
to be monitored both by traditional collectd consumers as well as the
connmon console for a quick "top" of connection activity. See the
"helloworld" example for further details.
