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:
