C.3.6.1 Debugging

To debug the channel, specify the master_debug channel keyword in the channel’s definition. For example,

sms_mway port 55555 threaddepth 20 \ 
backoff "pt2m" "pt5m" "pt10m" "pt30m" notices 1 master_debug

With the master_debug channel keyword, basic diagnostic information about the channel’s operation will be output to the channel’s log file. For verbose diagnostic information about the SMPP transactions undertaken by the channel, also specify

DEBUG=-1

in the channel’s option file.
