Add Linux machine on LibreNMS

Install SNMPD first

SNMPd is not installed by default. You must first install snmpd.

apt-get update
apt-get install snmpd lsb -y

Backup default snmp.conf file on the ‘/etc/snmp/’ directory and copy new one from the librenms directory.

mv /etc/snmp/snmpd.conf /etc/snmp/snmpd.conf.asli
cp /opt/librenms/snmpd.conf.example /etc/snmp/snmpd.conf

or instead copy-paste below snmpd text

# Change RANDOMSTRINGGOESHERE to your preferred SNMP community string
com2sec readonly default RANDOMSTRINGGOESHERE

group MyROGroup v2c readonly
view all included .1 80
access MyROGroup "" any noauth exact all none none

syscontact Your Name <your@email.address>

#Distro Detection
extend .1.3.6.1.4.1.2021.7890.1 distro /usr/bin/distro

Edit the new configuration.

vim /etc/snmp/snmpd.conf

Change the text ‘RANDOMSTRINGGOESHERE’ with your own community name as below.

com2sec readonly  default         public

That’s it. Save and exit Vim.
