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

You can safely ignore that one, see [https://github.com/elastic/logstash/issues/3087](https://github.com/elastic/logstash/issues/3087)
