Yes, use the --debug-daemon switch when you start smokeping.

I don't know how you're starting smokeping but here's the script I use
to do that in debug mode:

#!/bin/sh

# /etc/init.d/smokeping
#
### BEGIN INIT INFO
# Provides:          smokeping
# Required-Start:    $syslog $network
# Should-Start:      sshd apache
# Required-Stop:     $syslog $network
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Start or stop the smokeping latency logging system daemon
# Description:       SmokePing is a latency logging and graphing system
#                    that consists of a daemon process which organizes
#                    the latency measurements and a CGI which presents
#                    the graphs. This script is used to start or stop
#                    the daemon.
