cacti - generate graphs using bash scripts


I used "kazam" for screencapture in ubuntu 14.04.4
2016 april 1
Version 0.8.8b
ubuntu 14.04.4 LTS

cacti will also work with python scripts to create graphs

#create graph using script as data input
1 create script with output format"string:value" note the ":"
text:number -- remember this format
download:166 upload:14

the script should be saved in /usr/share/cacti/site/scripts
file permission should be like
-rwxr-xr-x 1 www-data www-data 208 Apr 1 12:20 testme.sh
the permissions for "others" can be removed
2 create data input methods
2.1 add output fields --it must match the out put field name of script)
eg. if out put is -- price:999 discounts:8787
then data output fields will be "price" and "discounts"
outof context examples ;

3 add data template
3.1 add Data Source Item
The Data Source Items should also match the output field names

4 create graph template
