Sometimes the user would like to dump all the metrics into a file or pipe it to another program, as requested in issue #1506. This patch makes scyllatop check if stdout is connected to a TTY, and if not - it does not fire up the fancy urwid UI but instead, just writes all it's collected metrics to stdout. Optionally, the user tell the program to quit after a specific number of iterations via the -n or --iterations flag Signed-off-by: Yoav Kleinberger <yoav@scylladb.com> Message-Id: <1471777516-9903-1-git-send-email-yoav@scylladb.com>
