[tor-relays] arm client locale stats on connection page

Hi, I am using arm to monitor 3 tor nodes running on the same box. On the connection page I get very different results when pressing "c" to get the client locale stats: Node A - nothing happens Node B - the window with the client locale stats is displayed Node C - a message "Usage stats aren't available yet, press any key..." is displayed Under which conditions are the stats available?
