mqforward

mqforward is forwarder from MQTT to Influxdb. This subscribes a topic with wildcard and forward a payload to Influxdb. The value should be JSON or msgpack.

for example,

• Publish {"a": 1, "b": 2} to "mqforward/a/b",
• Subscribe "mqforward/#",

in the influxdb,

• value a=1 and b=2 into the a.b series. so you can SELECT a, b FROM "a.b"

If udp is true in the config, send series over UDP to InfluxDB. otherwise, use HTTP.
