Configure SNMP on Proxmox VE
Install snmpd on a Proxmox host, give it a minimal read-only configuration limited to one monitoring server, and start it at boot.
Infrastructure linux proxmoxContents
SNMP (Simple Network Management Protocol) lets a monitoring system read a host’s CPU usage, network traffic, memory and more. This is how I set up the SNMP daemon on Proxmox.
Install snmpd
apt-get install -y snmpdKeep the original configuration
The configuration below replaces the default file entirely, so move the original aside first:
mv /etc/snmp/snmpd.conf /etc/snmp/snmpd.conf.bakWrite the configuration
This creates a read-only community called MYSNMP, allows only the monitoring
server at 10.10.10.1 to use it, and sets some basic system information. Copy the
whole block, from cat << to EOF:
cat << EOF > /etc/snmp/snmpd.conf
# This file will create a read-only community called "MYSNMP"
# and restricts access to address 10.10.10.1
rocommunity MYSNMP 10.10.10.1
syslocation "Bern, Switzerland"
syscontact "John Doe"
agentAddress udp:161
agentuser root
dontLogTCPWrappersConnects yes

EOFChange the community name, the allowed address, the location and the contact to your own.
Start the service and enable it at boot
service snmpd restart
update-rc.d snmpd enableThe host now answers SNMP queries from your monitoring server.
