Here is sample conf file:
Code:

#Ping is slow process. Use forks to ping multiple hosts at a time.
Forks: 10

Target[ping.google]: `/etc/mrtg/ping.sh www.google.com`
Title[ping.google]: Ping Google
PageTop[ping.google]: <H1>Ping Google</H1>
MaxBytes[ping.google]: 2000
Options[ping.google]: unknaszero,nopercent,gauge
ShortLegend[ping.google]:
LegendI[ping.google]: Pkt loss [%]
LegendO[ping.google]: Avg RTT [ms]
YLegend[ping.google]: RTT (ms)

Target[ping.yahoo]: `/etc/mrtg/ping.sh www.yahoo.com`
Title[ping.yahoo]: Ping Yahoo
PageTop[ping.yahoo]: <H1>Ping Yahoo</H1>
MaxBytes[ping.yahoo]: 2000
Options[ping.yahoo]: unknaszero,nopercent,gauge
ShortLegend[ping.yahoo]:
LegendI[ping.yahoo]: Pkt loss [%]
LegendO[ping.yahoo]: Avg RTT [ms]
YLegend[ping.yahoo]: RTT (ms)



Here is the script (/etc/mrtg/ping.sh):
Code:
#!/bin/sh
PING="/bin/ping"
ADDR="$1"
DATA=`$PING -c10 -s500 $ADDR -q `
LOSS=`echo "$DATA" |/usr/bin/tail -n 2|/usr/bin/head -n 1| awk '{print $6 }' | /usr/bin/tr -d %`
RTT=`echo $DATA |/usr/bin/tail -n 1| awk -F/ '{print $5 }'`

if [ -n "$LOSS" ] ; then
  LOSS=0
fi
if [[ "$RTT" == "" ]] ; then
  RTT=0
fi
echo $LOSS
if [[ "$LOSS" == "100" ]] ; then
              echo 0
else
  echo $RTT
fi
