SNMP Scripts to monitor Proxmox with PRTG

Configuration on Proxmox

Install snmpd

apt install snmpd

Configure snmpd

Paste content from snmpd.conf to /etc/snmp/snmpd.conf

nano /etc/snmp/snmpd.conf

Paste content from sh file to /opt folder and make executable

nano /opt/snmp-cpu-temp.sh
nano /opt/snmp-smart-status.sh
nano /opt/snmp-lvm-used.sh for LVM
nano /opt/snmp-zfs-used.sh for ZFS
nano /opt/snmp-ceph-used.sh for Ceph
chmod +x /opt/snmp-*

Run snmpd as root, because debian added the user "Debian-snmp" to the snmp.service but for SMART/LVM Status we need to be root.

edit snmpd.service and replace "Debian-snmp" with "root"

nano /lib/systemd/system/snmpd.service

From

ExecStart=/usr/sbin/snmpd -Lsd -Lf /dev/null -u Debian-snmp -g Debian-snmp -I -smux,mteTrigger,mteTriggerConf -f -p /run/snmpd.pid

To

ExecStart=/usr/sbin/snmpd -Lsd -Lf /dev/null -u root -g Debian-snmp -I -smux,mteTrigger,mteTriggerConf -f -p /run/snmpd.pid

Restart SNMPD

systemctl restart snmpd.service
