I have imported the Cisco MIBs for monitoring client associations on the 5508 controller according to these instructions:

However, when I try to add a sensor in PRTG only the generic SNMP and RFC sensors appear as available. None of the Cisco sensors are present. What am I missing?

(I have enabled all SNMP settings on the controller)

There's additional information regarding this matter on Cisco's Support Forum. Based on the supplied information, the key OID's for number of connected AP's and Clients are:

Number of Connected Clients1.3.6.1.4.1.9.9.618.1.8.12.0
Number of Connected AP's1.3.6.1.4.1.9.9.618.1.8.4.0

This can be set-up using our SNMP Custom Sensor, limits can be configured on the "Value" channel after the sensor's creation.

Alternatively, you can import the CISCO-DOT11-ASSOCIATION-MIB and deploy an SNMP Library Sensor. Please refer to the guide below:

Can't find a sensor for my device in PRTG but I believe it supports SNMP. How to proceed?

Did you convert the MIB file in case into a PRTG compatible OIDLIB file, as outlined on our MIB Importer page and added SNMP Library sensors, after selecting the OIDLIB in case?

If so, please scan against the device using the OIDLIB in case via our SNMP Tester. Does this yield any results?

Yes - created the OID file. When using SNMP Tester it reports No OIDs Found. It was searching for the correct OIDs so I think the import process worked. I have enabled all available SNMP options I can find in the device itself. Not sure what I am missing.

Could you walk the device tree to check if the respective OIDs are available?

Using the Scan Available OIDs from OIDLIB - none found. I have had success with other Cisco products but now have two, this controller, and another (Cisco CNR) that don't report anything. I thought it might be that the device was not configured to supply SNMP responses but have double checked everything I can find and they should respond.

In Case somebody likes to monitor the user count per "WLAN Profile Group" the corresponding OID is: .1.3.6.1.4.1.14179.2.1.1.1.38.NNN NNN is simply the WLAN ID.

Hi there.

So did someone finally manage to monitor the client count on a "per AP" basis? I do see that you can count the number of active APs and also the total amount of clients on a WLC - but nothing that really gives me "client/ap" count.

Thanks for your help! Flavio.
