We use Sawmill statistics reporting for our customers. Sawmill reports a wide variety of stream-by-stream statistics so you know not only how many viewers or listeners watched or listened but when they were connected and geographically where they are located, usually down to the city level. A full users' guide describing Sawmill capabilites can be accessed by clicking here.
A working demo of Sawmill from NetBroadcasting.tv is included by clicking here. Use the username demo and password demo.
