+## Pwrstatd
+
+Pwrstatd (commonly known as powerpanel) is an application/service available from CyberPower to monitor their PSUs over USB.  It is currently capable of reading the status of only one PSU connected via USB at a time.  The powerpanel software is available here:
+https://www.cyberpowersystems.com/products/software/power-panel-personal/
+
+### SNMP Extend
+
+1. Copy the python script, pwrstatd.py, to the desired host
+```
+wget https://github.com/librenms/librenms-agent/raw/master/snmp/pwrstatd.py -O /etc/snmp/pwrstatd.py
+```
+
+2. Make the script executable
+```
+chmod +x /etc/snmp/pwrstatd.py
+```
+
+3. Edit your snmpd.conf file and add:
+```
+extend pwrstatd /etc/snmp/pwrstatd.py
+```
+
+4. (Optional) Create a /etc/snmp/pwrstatd.json file and specify the path to the pwrstat executable [the default path is /sbin/pwrstat]:
+```
+{
+    "pwrstat_cmd": "/sbin/pwrstat"
+}
+```
+
+5. Restart snmpd.
+

 1. For Proxmox 4.4+ install the libpve-apiclient-perl package
