redis-statsd
redis-statsd is a small, dependency free Python program for periodically fetching stats via Redis' INFO
command and emitting them to a local StatsD.
Motivation
At Keen we run some Redis instances in Mesos with dynamically allocated ports. We use Datadog and therefore have an on-box StatsD instance to report to. Therefore this little program can be started with a dynamic port and report metrics out to DogStatsD!
Docker
A public docker image is available on docker hub.
Notes
A Word On Counters
Values that are counters in the stats from Redis are converted in to deltas by this program, since that's what StatsD expects.
Optional DogStatsD Tag Support
The --no-tags option will disable support for DogStatsD-style tags.
