This script uses `rec_control get-all` to collect stats.
### PowerDNS-dnsdist
###### SNMP Extend
1. Copy the BASH script to the desired host (the host must be added to LibreNMS devices)
```
wget https://github.com/librenms/librenms-agent/raw/master/snmp/powerdns-dnsdist -O /etc/snmp/powerdns-dnsdist
```
2. Make the script executable (chmod +x /etc/snmp/powerdns-dnsdist)
3. Edit your snmpd.conf file (usually /etc/snmp/snmpd.conf) and add:
```
extend powerdns-dnsdist /etc/snmp/powerdns-dnsdist
```
4. Restart snmpd on your host.
### Proxmox
1. For Proxmox 4.4+ install the libpve-apiclient-perl package
`apt install libpve-apiclient-perl`
