TTG (Text Traffic Grapher) is a small command line utility that displays current throughput (bandwidth usage) on an interface of a remote device, such as a router or switch, over SNMP (v1). You can think of TTG as command line version of STG or a high-interval/ad-hoc query/test tool for MRTG, etc. The output is very similar to the ping(1) command. You can use it to quickly check and measure traffic or when configuring MRTG.
