Please specify the setting below in the configuration file:

Commandline for statistics output:

fdpi_ctrl stat –proto

In the /etc/dpi/fastdpi.conf configuration file set the option:

dbg_log_mask=0x4

Reload the service:

service fastdpi reload

In the /var/log/dpi/fastdpi_stat.log file the output will be displayed according to the classes like following:

[STAT    ][2017/12/07-13:12:32:334249] HTB : Statistics dscp=2, if 'dna2' :
              DSCP_actual stats Rcvd: [0 bytes][0.00 Mbit/sec]
