> Hello, I receive the following error whenever I launch Logstash on a Windows 7, 64 bit VM: "IO/console not supported; tty will not be manipulated" This error always occurs, whether I define or not a Config file (using the -f parameter at launch). However, LS seems to eventually start successfully. Thanks for your assistance
