Nvidia GPU

Copy the shell script, nvidia, to the desired host

wget https://github.com/librenms/librenms-agent/raw/master/snmp/nvidia -O /etc/snmp/nvidia

Make the script executable
```
chmod +x /etc/snmp/nvidia
```
Edit your snmpd.conf file and add:
```
extend nvidia /etc/snmp/nvidia
```
Restart snmpd on your host.
```
sudo systemctl restart snmpd
```
Verify you have nvidia-smi installed, which it generally should be if you have the driver from Nvida installed.

The GPU numbering on the graphs will correspond to how the nvidia-smi sees them as being.

For questions about what the various values are/mean, please see the nvidia-smi man file under the section covering dmon.
