Client Health Map or Hierarchical Site/Building View dashlet

The Hide or Show button, allows you to hide or display this dashlet. By default, the Client Health Map dashlet displays.

This dashlet contains two buttons that allow you to display the health of the client devices in a map view or site/building view.

• Client Health Map—Click the map button to display health of all the client sites on a geographic location-oriented client health map. By default, the client sites that are represented are color-coded according to the severity of the problem.

  The color of the health score represents its severity. The health is measured on a scale of 1 to 10, with 10 being the best score, and a score of 0 for inactive clients.

• Click the button, and then choose the Hierarchical Site View or Building View from the drop-down list. Based on what you choose, the table displays information. To view information about a specific site, building, or floor, click Apply in the appropriate row; information is refreshed based on your selection.

Client Health dashlet

This dashlet includes the following information:

• Client Health Summary area—Contains a Client Health Summary score and a client count distribution trend chart. The Client Health Summary score is the percentage of healthy (good) wired and wireless client devices in your overall network or selected site. The client count distribution trend chart (located below the health score) shows the count of all clients over time, shown as a stacked area chart based on their health scores. See Client Health Summary Score.

• Wireless and Wired areas—Contains the following:

  • Score—The client category (Wired and Wireless) health score is the percentage of healthy (good) client devices in a target category. See Client Category Health Score.

  • Trend Chart—Health of clients displayed in a trend chart (located on the right of the health score).

  • Donut Chart—Provides a count of poor, fair, good, and inactive client devices. The client devices are color-coded and broken down according to the severity of the scores. Hover your cursor over a specific color on the donut chart to display the number of clients associated with that color.

Client Devices Table dashlet

• Filter the table based on client type, client health, and data.

  • Client Type—Options are wired and wireless clients.

  • Client Health—Options are:

    • Poor—Client devices with a health score range from 1 to 3.

    • Fair—Client devices with a health score range from 4 to 7.

    To determine the threshold values for onboarding, association time, DHCP, and AAA, from the Client Attempts on Onbording Time dashlet, click View Details. From the side bar that opens, click the appropriate option, and then view the value in the Threshold legend.

    To determine the threshold value for RSSI, see the Threshold legend in the Connectivity RSSI dashlet.

• View client device information in a table format. The client device table lists information about client devices, such as user ID, hostname, MAC address, IP address, device type, last heard, location, VLAN ID, SSID, and the following information:

  • Overall Health Score—This score is the sum of the onboarding and connected scores.

  • Onboarding Score—Indicates the experience of a client device while connecting to the network; whether the client connected (onboarded) to the network successfully or not. For more information, see Client Onboarding Score.

  • Connected Score—Indicates the experience of a client device after the device is connected to the network. For more information, see Client Connectivity Score.

  • Connected To—Provides the following information:

    • Wireless Clients—Provides the name of the AP or Cisco WLC to which the client device is connected.

    • Wired Client—Provides the name of the switch to which the client device is connected.

• Display a 360° view of a client by clicking the MAC address of a client device.

Individual Client Health Score

If you search by the host name or user ID, the Individual Client Health score that is displayed is the minimum score of all the monitored client devices associated with that user. For more information, see Individual Client Health Score.

If you search by MAC address or IP address, the Individual Client Health score is the health score for that client device.

The color of the health score represents its severity. The health is measured on a scale of 1 to 10, where 10 is the best score. A score of 0 indicates that data could not be obtained.

• Red—Poor client devices. Health score range is 1 to 3.

• Orange—Fair client devices. Health score range is 4 to 7.

• Green—Good client devices. Health score range is 8 to 10.

• Gray—Inactive client devices. Health score is 0.

Details about each of the client's devices is represented in a separate tab, for example, username-macbook or username-iphone.

Hover your cursor over a tab to view details about a device, such as device type, OS version, MAC address, and IP address.

Historical Health, Events, and Band Frequency Graph

Health, events, and band frequency information about the selected client device over a period of time displayed in a graph.

• Health—To obtain the health score at a particular time, hover your cursor over the time instance on the graph, for example, you can hover your cursor at 7:00, 7:05, 7:20, and so on.

  When you click a time, for example, 7:05, the entire page is refreshed, providing updates for that point of time. Note that the timestamp next to each category (Issues, Onboarding, Event Viewer, Connectivity, and so on) is also refreshed.

• Events—Event data is displayed by color-coded vertical bars on the graph. Green vertical bars indicate successful event(s) and the red vertical bars indicate event(s) that failed.

  Each vertical bar represents 5-minutes of time. Multiple significant events can be generated during each 5-minute window. Hover your cursor over the vertical bar to get more information about the event(s).

• Band—Band frequency data is color-coded and displayed as a horizontal line at the bottom of the graph. Light blue color represents 2.4 GHz band frequency and purple color represents 5 GHz band frequency. A gap in the horizontal line indicates that either the client device is not connected to the network or that the client device is not sending data.

If you do not want to view the event or band frequency data in the graph, uncheck the Events or Band check box in the Displayed Data area.
