##Upgrading to batsd

Batsd uses the same storage format for on-disk storage, but a slightly different format for redis storage. The preferred way to migrate is:

1. Install and configure batsd to use the same data path (called root in batsd).

2. Stop statsd-server

3. Execute FLUSHALL in the redis instance. You may wish to dump the datapoints set to a file and reload it afterwards if you rely on that being fully comprehensive.

4. Start batsd.

5. Switch to the batsd client.

This does mean some data will be lost at the lowest granularity. It will be available at the next level of granularity that was stored to disk.

Alternately, you can mirror incoming statsd traffic to multiple ports running both statsd-server and batsd, pointing at different Redis instances to build up equivalent amounts of short term data in both.

You can accomplish this with socat -- the following will send UDP traffic from port 8125 to both port 8135 and 8140, so you can run batsd and statsd-server simultaneously.

socat - udp4-listen:8125,fork | tee >(socat - udp-sendto:127.0.0.1:8135) >(socat - udp-sendto:127.0.0.1:8140)
