Since version 1.6 dsdccx has the capability of sending regularly the traffic status messages to a file using the -M option. The -m option specifies the rate at which the information is polled and written to file. It is expressed in seconds at a 48 kS/s rate and has a minimum value of 0.1s. At 0.1s it will poll everu 48000*0.1 = 4800 samples.
The polling period will match an actual time interval only during live operation when samples are fed from a real device although buffering might alter this.
There is one line per polling occurrence with a fixed format depending on the protocol. For all protocols the line starts with a timestamp and a protocol identifier. Details by protocol are given next.
