Ahhhh Cacti! It’s wonderful when it works! Yes, yes, those beautiful graphs look great. However, it’s true that when you want to create your own graph, that’s a different story! So I found this comprehensive documentation that works perfectly as long as you follow it to the letter!

Documentation on creating a graph in Cacti

Now that you know how to create graphs, here are some scripts I made a while ago.

CPU Graph

CPU Graph - /usr/share/cacti/site/scripts/cpu-stats.sh

CPU Graph

  MYTOP=`top -b -n 2 | grep Cpu | tail -1`
USAGE=`echo $MYTOP | awk '{ print $2 }' | awk -F"%" '{ print $1 }' | awk -F"." '{ print $1 }'`
SYSTEM=`echo $MYTOP | awk '{ print $4 }' | awk -F"%" '{ print $1 }' | awk -F"." '{ print $1 }'`
IDLE=`echo $MYTOP | awk '{ print $8 }' | awk -F"%" '{ print $1 }' | awk -F"." '{ print $1 }'`
typeset -i USAGE
typeset -i SYSTEM
typeset -i IDLE
printf "cpu_usage:%d cpu_system:%d cpu_idle:%d\n" $USAGE $SYSTEM $IDLE

Mldonkey Graph

Mldonkey Graph - /usr/share/cacti/site/scripts/mldonkey-stats.sh

Mldonkey Graph

  MY_ML=`mldonkey_command bw_stats -p "" | grep Down`
ML_DOWN=`echo $MY_ML | awk '{ print $2 }' | awk -F. '{ print $1 }'`
ML_UP=`echo $MY_ML | awk '{ print $11 }' | awk -F. '{ print $1 }'`
ML_FILES=`mldonkey_command vd -p "" | grep "\[D " | wc | awk '{ print $1 }'`
typeset -i ML_DOWN
typeset -i ML_UP
typeset -i ML_FILES
printf "ml_down:%d ml_up:%d ml_files:%d\n" $ML_DOWN $ML_UP $ML_FILES

RAM Graph

RAM Graph - /usr/share/cacti/site/scripts/ram-stats.sh

RAM Graph

  MY_RAM=`free -o | grep "Mem:"`
RAM_TOTAL=`echo $MY_RAM | awk '{ print $2 }'`
RAM_USED=`echo $MY_RAM | awk '{ print $3 }'`
RAM_FREE=`echo $MY_RAM | awk '{ print $4 }'`
typeset -i RAM_TOTAL
typeset -i RAM_USED
typeset -i RAM_FREE
printf "ram_total:%d ram_used:%d ram_free:%d\n" $RAM_TOTAL $RAM_USED $RAM_FREE
