Cacti Templates, data collection script for Linux lm-sensors
Author Marco Re
Template version: 0.1 Cacti version: 0.8.8a and above

I created these Cacti templates to collect Linux servers temperature, fan and voltage.

Advantages:

• Data are collected only via snmp
• Lower load against collecting data via ssh command
• It is possible to add another values
• You can use data from shell script or a binary

Templates contains 3 types of graphs:

1. Fan
2. Temperature
3. Voltage

Installation:

1. install snmpd

apt install snmpd

• edit /etc/snmp/snmpd.conf
  • change location, community, ...

cp net-snmp/net-snmp-cacti.conf /etc/snmp/snmpd.conf.d
service snmpd start

2. Shell scripts

mkdir /usr/local/vbin/
chown root /usr/local/vbin/
chmod 755 /usr/local/vbin/
cp shellscripts/cacti_*.sh to /usr/local/vbin/
chown root /usr/local/vbin/cacti_*.sh
chmod 750 /usr/local/vbin/cacti_*.sh

3. crontab add to /etc/crontab this line

*  *  *  *  * root /usr/local/vbin/crontab_script.sh

• NOTE inside the script there is a check if the file is not older than THRESHOLD_MINUTES is not updated

4. Import templates
   • import templates/*.xml (console -> import templates)
