Configure Network Analytics Thresholds
Network Analytics are computed based on usage threshold values configured at Organizational level and Site level. To change a usage threshold value, click on the respective button on the Network Analytics Dashboard as described below.
The Network Analytics Summary at the top of the dashboard displays the total number of Access Points, Access Points Up, Down Count and number of Live Wireless and Wired Clients connected in the Network.
Configure Device List Health Thresholds
The Access Points Health analytics for CPU, Memory and Flash Health metrics can be computed based on Device List Health threshold values of the devices. The Device List Health Thresholds button appears on the “Device List” button when you are looking at a specific Site to view the Access Points Health as shown below:
This opens the “Configure Thresholds for site” window from which you can configure the following threshold values:
After changing any of the threshold values, click the Save button. To revert thresholds to their default values, click the Reset to default button.
Configure Device Health Thresholds
The Access Points Health analytics for CPU and Memory Health metrics can also be computed based on Device threshold values of the devices. The Device Thresholds button appears when you selects an Organization level/Site level/Building level or Floor level to view the Access Points Health.
To set a device threshold for the Access Points, click on the Device Thresholds button on the Access Points Health Dashboard. This opens the window in which you can select the Access Points for which you want to edit the threshold values.
When you click on one of the Access Points, it opens the “ Edit Health Thresholds” window from which you can edit the following threshold values for the Access Points:
After changing any of the threshold values, click the Save button. To revert thresholds to their default values, click the Revert button.
Configure Site Health Thresholds
The Client Health analytics can also be computed based on Site threshold values of the devices. The Site Thresholds button appears next to the Device Thresholds button when you are looking at a specific Site to view the Access Points Health as shown below:
To set a Site threshold value for a specific Site, click on the Site Thresholds button. The following screen appears from which you can edit the following threshold values for the Access Points:
Client Health (2.4 GHz) threshold (%): Defaults to 60% usage.
Client Health (5 GHz) threshold (%): Defaults to 60% usage.
Client SNR (2.4 GHz) threshold (%): Defaults to 15% usage.
Client SNR (5 GHz) threshold (dbm): Defaults to 15% of usage.
Radio Noise (2.4 GHz) threshold (dbm): Defaults to -92% of usage.
Radio Noise (5 GHz) threshold (%): Defaults to -92% of usage.
Radio Utilization (2.4 GHz) threshold (%): Defaults to 50% of usage.
Radio Utilization (5 GHz) threshold (%): Defaults to 50% of usage.
Radio Interference (2.4 GHz) threshold (%): Defaults to 25% of usage.
Radio Interference (5 GHz) threshold (%): Defaults to 25% of usage.
Retransmissions threshold (%): Defaults to 10% of usage.
Errors threshold (%): Defaults to 5% of usage.
After changing any of the threshold values, click the Save button. To revert thresholds to their default values, click the Reset to default button.
Notes:
The Site health threshold is a global threshold that applies to all the devices belonging to that Site. It can be overridden by the device health threshold which is configured with the Device Thresholds option.
Changing any of the default Site or device threshold values will recalculate all three of the parameters of the Access Points Health dashboard and will change the threshold line in the Access Points Health Table. It is used to count number of healthy Access Points corresponding to the threshold values.
Both the Device Thresholds and Site Thresholds options are available only for the Access Points Health Thresholds metrics.
