View source for Scheduled check for loaded interfaces (auto adding queue to some IP or interface)

If you have MikroTik as main router on your network (business and residential clients using the same downlink) and you want to create QoS for business users.

Simple:
If your downlink is about 2Mbps and you want to grant the business clients min 1Mbit. 
But on the same MikroTik you have connected residential users.
<br>
This script can check out-interface (for $sent-bits-per-second/$received-bits-per-second)
and if sent/received bits > 1Mbps, script can add queue for some interface or IP address(es).
