Thank you for your KB Post. As there are no native Huawei Sensors available in PRTG, it depends on whether the physical device you want to monitor supports protocols that PRTG uses.
The most common are SNMP, Netflow, Sflow or WMI. PRTG is also able to monitor various types of servers (Webserver, FTP, DNS, SQL, etc. to see the full list of available sensor types, please take a look at: http://www.paessler.com/manuals/prtg/available_sensor_types.htm).
You can test the most common protocols with one of our freeware networking tools: http://www.paessler.com/tools
