COMMAND_KEY_INPUT_REQUEST

public static final String COMMAND_KEY_INPUT_REQUEST

Requests from a client - what an operator reads as "how much traffic is this node taking". Kept as an alias of FcCommandKeys.INPUT_REQUEST rather than replaced by it: this is where the key has always been referenced from, and the indirection costs nothing.
