Performance metrics of a wireless LAN controller
After you add a wireless LAN controller (WLC) monitor, Site24x7 will start collecting the performance metrics of your Cisco WLC device to analyze the connections. You can set thresholds for these metrics to receive alerts if any of the limits are breached. This ensures that you stay in control and are notified if anything goes wrong.
The performance metrics are categorized according to the following:
Figure 1. The Cisco WLC view.
Access Points

| Admin Status | The admin state of the access point: Enable (1) Disable (2) |
| Operational Status | The operational status of the access point: 1: associated 2: disassociating 3: downloading |
| CPU Utilization (%) | The current CPU load of the access point as a percentage |
| Memory Utilization (%) | The current memory utilization of the access point as a percentage |
| Connected Clients Count | The number of clients currently connected to the access point |
| Status | The status of the access point: Up, Down, Critical, or Trouble |
Radios
