Monitor wireless LAN controllers and the infrastructure they manage. Track availability, response time, access point count, connected clients, rogue SSIDs, and more from a single view.
Cloudmon monitors wireless LAN controllers using SNMP, collecting availability, performance, and device data at regular polling intervals. Once a controller is added, all access points, SSIDs, and clients associated with it are discovered automatically. Navigate to Network → Wireless Devices to access the wireless overview, which shows total WLC count, access point count, SSID count, active clients, and rogue SSID count across the environment.
The overview page ranks controllers by client count and access point count, and distribution charts break the fleet down by vendor and model, giving teams an immediate picture of the wireless environment without drilling into individual devices.
Before adding a wireless controller, confirm the following:
Each WLC has a detailed view showing availability, downtime count, and response time in the summary header alongside the SSID count, client count, rogue SSID count, access point count, and active alarm state. This gives teams an immediate read on the controller and everything it is managing without needing to access the controller directly.
A Device Information panel surfaces the system name, description, vendor, model, hardware version, software version, MAC address, serial number, and maximum access point limit. An Overview panel shows the full AP hierarchy as a treeview, making it easy to see exactly which access points are registered to the controller and their current status. Interface status is shown as a colour-coded map alongside the treeview.
Because access points, SSIDs, and clients are discovered automatically from the controller, there is no need to add them individually. A controller added to Cloudmon immediately populates the Access Points, SSIDs, and Clients views with everything it manages, giving teams full wireless visibility from a single registration step.
Alarm triggers can be configured per controller to alert on availability, response time, client count thresholds, and rogue SSID detection. Learn more.
| Symptom | Likely Cause | Fix |
| Controller not appearing after adding | SNMP credentials are incorrect or the probe cannot reach the controller on UDP port 161 | Verify the IP address, confirm SNMP is enabled on the controller, check port 161 is open, and re-test the credential |
| Controller showing as Down | The controller is unreachable from the probe or SNMP credentials have changed | Check network connectivity to the controller and verify the assigned SNMP credential is still valid |
| Access points not appearing | The controller has not completed its first full poll, or the APs are not registered to the controller | Wait for the next poll cycle and confirm the APs are associated to the controller in its management interface |
| High rogue SSID count | Neighbouring wireless networks are being detected by the access points | Review the Rogue SSID list and classify known neighbouring networks to reduce false positives |
