-Usage:
-
-    "${0}" start|stop PORT [BACKEND_HOST BACKEND_PORT]
-
-    PORT          The port this script will listen
-                  (configure netdata to use this as a second backend)
-
-    BACKEND_HOST  The real backend host
-    BACKEND_PORT  The real backend port
-
-    This script can act as fallback backend for netdata.
-    It will receive metrics from netdata, save them to
-    ${FILE}
-    and once netdata reconnects to the real-backend, this script
-    will push all metrics collected to the real-backend too and
-    wait for a failure to happen again.
-
-    Only one netdata can connect to this script at a time.
-    If you need fallback for multiple netdata, run this script
-    multiple times with different ports.
-
-    You can run me in the background with this:
-
-    screen -d -m "${0}" start PORT [BACKEND_HOST BACKEND_PORT]
