The correct way is to use ping probe.  It works.

However, I like shell scripts so I wrote this one that
extracts the ping times from a single packet ping and
belches the numbers in the proper format.  Your unspecified
operating system may have a different ping command and
formatting, so be careful here.  Just install this shell
script where MRTG can find it and run it from the "target"
line in mrtg.cfg.

retch=`ping -c 1 -s 1025 $1 | grep "time"`	# extract line with ping time.
set $retch	# break apart into fields using IFS seperators
ping=`echo $8 | cut -c 6-`	# extract print time.
echo $ping	# ping time=xxx
echo $ping	# ping time=xxx
