Urutan pembuatannya sbb :
1. Tempatkan script di bawah pada folder '<path_cacti>/scripts/wjspeed.sh'
Pastikan ownernya dan attribut file tsb dapat dieksekusi (chmod 555/755)
#!/bin/bash

export WJ_FILETMP=/tmp/wjspeed.tmp
export WJ_FILELOG=/tmp/wjspeed.log
export WJ_TARGET=192.168.1.1
export WJ_USER=root
export WJ_PASS=Zte521
export WJ_INTR=ppp0
echo -n "`date`" > $WJ_FILETMP
# Start the expect script
(expect -c "
set timeout 10
# Start the session with the input variable and the rest of the hostname
spawn telnet $WJ_TARGET

send \"ifconfig $WJ_INTR | grep bytes\r\"
expect \"*#\"
send \"exit\r\"
#
# stop the expect script once the telnet session is closed
exit
") | grep RX | sed -e 's/^ //g' | sed -e 's/:/=/g' >> $WJ_FILETMP

then

#echo " RX bytes=0 (0 MiB) TX bytes=0 (0 MiB)" >> $WJ_FILETMP
if [ "`wc -l $WJ_FILELOG | cut -d' ' -f1`" = "2" ]
then

#After restart R2&T2 will be 0, R1&T1 will still using old counter
[ "$TBPS" -ge "1250000" ] && TBPS=0

2. Buat 'Data Input Methods'
3. Buat 'Data Templates'
4. Buat 'Graph Templates'
Selamat Mencoba
