Monitoring Cisco WLC, AP's, SSIDs

Votes:

0

I'm working thru our WiFi setup with an instance of PRTG as our monitoring solution.

I'm trying to find a way to monitor bandwidth usage. Both clients connected to the AP's and the traffic per SSID.

Current setup: - 2 - 2504s and roughly 20 - 3700i APs, and getting quotes on upgrade to a 3504s and planning for an integration to 3800 APs - Roughly 350 clients.

My ideal solution, for now, would be to use PRTG to monitor -> make a graph available to our IT staff so we all can quickly look and see if when we start to get "WiFi is SLOW" tickets:

So really monitor and graph: - Total Number of clients connected - Number of clients connected to each AP - Number of clients connected to each SSID, each SSID per AP would be great too - Bandwidth usage at both the AP and SSID levels

I downloaded and installed a solution, link below, from the PRTG forums last week. At quick glance though it looks a little clunky and not sure if it's going to give me everything that I need. When I say quick glance I spent a few hours getting it up and running. Then another few hours making and installing oilib's.

Anybody have advice on this. I'll need to do this for 3 additional offices too.

Hi aaronjk,

To display different graphs/channels in one view, we recommend to use a Map. With the Maps feature you can create web pages with up-to-the-minute monitoring status information in a customizable layout. Furthermore, as the other Knowledge Base article describes, the best way to monitor the bandwidth is to use the SNMP Traffic Sensor. For more values like " Number of clients connected" I recommend to use a SNMP Custom Sensor / SNMP Custom Advance Sensor / SNMP Library Sensor. With these Sensors you are able to monitor manufacturer specific OIDs. Therefore, if the manufacturer provides an appropriate OID, PRTG can monitor it.

To import a custom MIB file, please use our MIB Importer and save the OIDLib in the directory: "<Your PRTG installation path>\snmplibs". Afterwards, you should use the SNMP Library Sensor to use the OIDLib.

For more detailed information about the mentioned Sensors, please follow these links: - https://www.paessler.com/manuals/prtg/snmp_traffic_sensor - https://www.paessler.com/manuals/prtg/snmp_library_sensor - https://www.paessler.com/manuals/prtg/snmp_custom_sensor - https://www.paessler.com/manuals/prtg/snmp_custom_advanced_sensor
