It's a bit obscure. The log messages are actually always sent to stdout. Usually this is the console, but command arguments can cause traffic_server to reset stdout (file descriptor 1) to a file (normally traffic.out). These are the `--bind_stdout` and `--bind_stderr` command line options (which, sadly, are not documented. Should fix that...). If you want to see them being used, use `trafficserver start` and then use "ps aux" to look at the command line for "traffic_server" - you should see them there.
