we are monitoring an Aerohive 330 and want to create a script that counts the current users connected to the device. This vendor doesn´t have this SNMP variable in their devices, but there is an OID that could give the IP list of connected clients. 

So we need help to build a script that polls this OID with snmp, and "count" the IPs in the response so we can get an integer number and have a graphic with the user count connected during the day.

IS this possible creating a script monitor? 

We are new using windows scripts, somebody can share an example code?
