cAdvisor supports exporting stats to statsd. To use statsd, you need to pass some additional flags to cAdvisor telling it where to find statsd:
Set the storage driver as statsd.
-storage_driver=statsd
Specify what statsd instance to push data to:
# The *ip:port* of the instance. Default is 'localhost:8086'
-storage_driver_host=ip:port
The easiest way to get up an running is to start the cadvisor binary with the --storage_driver and --storage_driver_host flags.
cadvisor --storage_driver="statsd" --storage_driver_host="localhost:8125"
The default port for statsd is 8125, so this wil start pumping metrics directly to it.
