+Centrifuge also allows to collect and export various metrics into Graphite.
+You can configure metric collecting and exporting behaviour using ``metrics``

+At moment Centrifuge collects for each node:
+
+* broadcast - time in milliseconds spent to broadcast messages (average, min, max, count of broadcasts)
+* connect - amount and rate of connect attempts to Centrifuge
+* messages - amount and rate of messages published
+* channels - amount of active channels
+* clients - amount of connected clients
+* unique_clients - amount of unique clients connected
