SNMP & Cacti Configuration

Basically, i refer my SNMP and Cacti installation here. It works nicely. I would like to paste here everything i have done to make it works in my PC.

Below is how the architecture looks since I want Cacti to monitor many devices at a time. Firstly, assign one PC as manager (which Cacti will be installed) and all of devices to be monitored. They are connected using SNMP.

Below is the setting I had done to my manager:

1) Firstly, install SNMP

$sudo apt-get install snmpd

2) Then check

$sudo gedit /etc/default/snmpd

Make sure

# snmpd control (yes means start daemon).

SNMPDRUN=yes

# snmpd options (use syslog, close stdin/out/err).

SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid 127.0.0.1'

3) Next,

$sudo gedit /etc/snmp/snmpd.conf

In the line of com2sec setting, I have adjusted as below (slightly different from How-To)

# sec.name source community

com2sec readonly localhost public

If you have your own community, you could use it for better security.

4) Check SNMP configuration

$snmpwalk -Os -c public -v 1 localhost system

(If you use your community, replace 'public' with your community name)

This command will return result something like this:

5) CACTI- Installation

I did exactly like here.

For all other devices, configure SNMP server same like above. That's all :)
