System Health Indicators

Down Devices

This graph shows the count of devices with DOWN status. The graph displays the following information:

Total number of devices

Number of unique devices that were DOWN

Minimum and maximum device downtime.

To view more details, select a time range in the graph and click on See Devices. A pop-up window displays the details of devices with DOWN status and their Up and Down time in percentage. You can also add other metrics such as CPU, Memory, 5 GHz and 2.4 GHz Channel Utilization, and 5 GHz and 2.4 GHz Noise Floor by clicking on the Add Metric button. A particular device can be filtered from the list by clicking on the filter icon ()and entering the name of the device.

High CPU & High Memory

This graph shows the total count or percentage of devices with high CPU utilization and high memory utilization.

High CPU Utilization—This graph displays the total number of devices, number of unique devices with high CPU utilization, and minimum and maximum number of devices with high CPU utilization. You can also view the total count or percentage of maximum and minimum number of devices with high CPU utilization for a specific time when you hover your mouse over the graph.

High Memory Utilization—This graph displays the total number of devices, number of unique devices, the minimum and maximum number of devices with high memory utilization. You can also view the total count or percentage of maximum and minimum number of devices with high memory utilization for specific time when you hover your mouse over the graph.

Threshold Setting Widget—You can also choose to view the graph details based one of the following criteria by clicking the (Threshold Setting Widget) icon and selecting any of the following options:

>70% CPU utilization

>80% CPU utilization

>90% CPU utilization

>70% memory utilization

>80% memory utilization

>90% memory utilization

To view more details, select a time range in the graph and click on See Devices. A pop-up window displays the details of devices with high CPU utilization and memory utilization with their individual minimum and maximum values. You can add other metrics such as 5 GHz and 2.4 GHz Channel Utilization , 5 GHz and 2.4 GHz Noise Floor, and Device Down time for the devices by clicking on the Add Metric button. A particular device can be filtered from the list by clicking on the filter icon () and entering the name of the device.

RF Health Indicators

5 GHz Utilization and Noise

This graph displays the total count or percentage of devices with high channel utilization and high noise floor levels for 5 GHz band.

Device Details—The graph displays total number of devices, number of unique devices with high 5 GHz channel utilization and high noise floor levels, and the minimum and maximum number of devices with high channel utilization. You can also view the total count of maximum and minimum number of devices with high 5 GHz channel utilization and noise for a specific time when you hover your mouse over the graph.

Threshold setting—You can also choose to view the graph details based one of the following criteria by clicking the (Threshold Setting Widget) icon and selecting any of the following options:

>60% 5 GHz Utilization

>70% 5 GHz Utilization

>80% 5 GHz Utilization

>-75 dBm 5 GHz Noise

>-80 dBm 5 GHz Noise

>-85 dBm 5 GHz Noise

To view more details, select a time range in the graph and click on See Devices. A pop-up window displays the details of devices with high CPU utilization and memory utilization with their individual minimum and maximum CPU utilization values. You can add other metrics such as CPU, Memory, 2.4 GHz Channel Utilization, 2.4 GHz Noise Floor, and Device Down time for the devices by clicking on the Add Metric button. A particular device can be filtered from the list by clicking on the filter icon () and entering the name of the device.

2.4 GHz Utilization and Noise

This graph displays the total count or percentage of devices with a higher channel utilization and high noise floor levels for 2.4 GHz channel.

Device Details—The graph displays the total number of devices, number of unique devices with high 2.4 GHz channel utilization and noise floor levels, minimum and maximum number of devices with high channel utilization and noise levels. You can also view the total count of maximum and minimum number of devices with high 2.4 GHz Utilization and Noise for a specific time when you hover your mouse over the graph.

Threshold Setting widget —You can also choose to view the graph details based one of the following criteria by clicking the (Threshold Setting Widget) icon and selecting any of the following options:

>60% 2.4 GHz Utilization
