*** Nova Mood Still Under Construction ***

Thanks to jesusaurus for a ton of nova_service_test.py code. It was a huge chunk of excellent clay to start with!

Nova Mood Synopsis

1. Provide nova action metrics database (setup script included)

2. Provide analysis queries

3. Provides python-novaclient wrapper with nova_collect decorator that:

   -- throttles requests, to smooth out request flow -- retry with exponential back off -- this keeps things going when we get rate-limited -- collect metrics for every request that is made -- wrap atomic nova actions -- wrap parent actions (which contain several atomic actions) -- collect any error that is encountered -- collect soft errors (like rate-limiting) and keep going -- collect hard errors (like 500) and keep going if possible -- collect timeout errors when vm cannot be pinged or ssh'd to -- synchronize requests -- if env needs it (currently bravo is happier) -- if nova env works with sync, fails without sync, concurrency is a problem

4. All nova request actions are tagged with date time, so concurrent (multi-account) metrics can be collected -- it's important to know what tests are going on where and when, to make the result data set more intelligible

CONFIGURE:

1. configure settings, nova auth, db_auth, and scaling settings in config.yaml

-- really, the default config.yaml should require only setting the nova account info.

0. setup a nova_mood MySQL database by running nova_mood_db.py script

RUN: python controller.py

TODO: bugbugbug - write more detailed notes about how to configure and run this stuff
