Adding StatsD logging to Swift. Documentation, including a list of metrics reported and their semantics, is in the Admin Guide in a new section, "Reporting Metrics to StatsD". An optional "metric prefix" may be configured which will be prepended to every metric name sent to StatsD. Here is the rationale for doing a deep integration like this versus only sending metrics to StatsD in middleware. It's the only way to report some internal activities of Swift in a real-time manner. So to have one way of reporting to StatsD and one place/style of configuration, even some things (like, say, timing of PUT requests into the proxy-server) which could be logged via middleware are consistently logged the same way (deep integration via the logger delegate methods). When log_statsd_host is configured, get_logger() injects a swift.common.utils.StatsdClient object into the logger as logger.statsd_client. Then a set of delegate methods on LogAdapter either pass through to the StatsdClient object or become no-ops. This allows StatsD logging to look like: self.logger.increment('some.metric.here') and do the right thing in all cases and with no messy conditional logic. I wanted to use the pystatsd module for the StatsD client, but the version on PyPi is lagging the git repo (and is missing both the prefix functionality and timing_since() method). So I wrote my swift.common.utils.StatsdClient. The interface is the same as pystatsd.Client, but the code was written from scratch. It's pretty simple, and the tests I added cover it. This also frees Swift from an optional dependency on the pystatsd module, making this feature easier to enable. There's test coverage for the new code and all existing tests continue to pass. Refactored out _one_audit_pass() method in swift/account/auditor.py and swift/container/auditor.py. Fixed some misc. PEP8 violations. Misc test cleanups and refactorings (particularly the way "fake logging" is handled). Change-Id: Ie968a9ae8771f59ee7591e2ae11999c44bfe33b2
