In order to view the debug log files, “less” or “tail” can be used. The keyword “mp-log” links to the management-plane logs (similar to “dp-log” for the dataplane-logs). The tail command can be used with “follow yes” to have a live view of all logged messages.
Use the question mark in order to display all possibilities.
Examples:
#less mp-log ?
#less mp-log dnsproxyd.log
#tail follow yes mp-log dhcpd.log
#tail follow yes mp-log routed.log
