Dashboards
CV-CUE provides varied widgets on its Connectivity and Performance dashboards that promote actual cause of issue, not just related client statistics, to drive faster troubleshooting efforts. With Dashboards, you receive immediate feedback when performing remediation thus democratizing Wi-Fi troubleshooting for level one and junior support staff.
Where applicable, dashboard widgets show values for both IPv4 and IPv6. This gives a more granular view of the network. For example, the Average Latencies widget on the Performance Dashboard shows the latency values for both v4 and v6 paths, helping you identify if the issue lies with only one of the IP addresses.
Connectivity Dashboard
The Connectivity Dashboard provides the health of all the clients and devices that are present in a WLAN network, on the selected folder or floor. It comprises of a number of widgets which provide information of the connectivity strength in a single glance.
Navigate to Dashboard > Connectivity to view the Connectivity Dashboard.
The Connectivity Dashboard contains the following widgets:
- Client Journey
- It provides an overview of various aspects of the client such as number of active clients, associations to the Wi-Fi, successfully authenticated clients, total number of clients connected to the network, and number of online clients.
- Clients by Most Failed Connections
- Lists the number of times a client failed to connect. The clients are listed in decreasing order of failed attempts and then alphabetically.
- Top Locations Affected by Failures
- Displays the top five locations which are affected by association, authentication or network failure. The locations are listed in decreasing order based on the percentage of connection failures.
- Baseline - Clients Affected by Failures
- CV-CUE calculates a baseline for the percentage of clients that failed due to connectivity issues. The connectivity issues taken into consideration are: Authentication failure, Association failure, and Network failure.
Client Journey
Client Journey depicts the current state of the network for the selected folder or floor. It provides an overview of various aspects of the client such as number of active clients, associations to the Wi-Fi, successfully authenticated clients, total number of clients connected to the network, and number of online clients.

You can hover the mouse over the different phases of the client journey to get additional information. For example, if you hover the mouse over the Authentication phase, a tool tip displays information such as percentage of authenticated clients, number of clients who failed to authenticate, type of authentication failure with the number of clients that failed to authenticate for a type of authentication.
You can click on the different phases to view detailed information of each phase. For example, if you click Association, you will be redirected to a page that provides detailed information of the client health displaying a list of clients that failed to associate.
- Total Clients
- The Total Clients section displays the number clients that connected or tried to connect to the network. It includes the total number of clients that associated with an SSID on the network and the total number of clients that failed to associate. Click Total Clients to view a list of clients with their detailed information.
- Association
- The Association section displays the total number of clients that are successfully associated to a Wi-Fi network and the total number of clients that failed to associate to the Wi-Fi network. Click Associations to view a list of clients with failed associations.
- Authentication
- The Authentication section displays the total number successfully authenticated clients and the clients that failed to authenticate through the Wi-Fi network.
- Network
- The Network section displays the total number of clients that could successfully access the network services like DHCP, DNS and also those that failed to access these services.
- Online
- The Online section displays the total number of online clients that successfully connected to the Wi-Fi network. It also displays the total number of clients that failed to authenticate, associate or access the network.
- You can search a client by providing MAC address, IP address, user name or device name. You get the status of the various phases of that client, with the time stamp.
Search Icon on Client Journey
You can search an active client by providing MAC address, IP address, user name or device name. You get the status of the last attempted connection, in the various phases of the active client, with a time stamp.
- No connection records found in currently active clients: No results are displayed because the searched active client is not available on the selected folder or floor.
- Search historical client records?: A link that suggests to look for the searched client in the historical records. This option is displayed when the searched client was active in the past and unavailable at the moment. After clicking on the link, you are redirected to the list of clients and you can click on the name of the client for a detailed information.

You can view or retrieve data using the filters. To know more about these filters refer to Filters on Widgets.
The data of the network usage chart can be filtered based on two parameters; a client's data and the amount of data used by an application.
Drill down on the data point on the graph, redirects you to the page containing client connections table. This table contains the list of all the client connections along with their detailed information for the selected timestamp. For client details, refer to Filtered Network Usage Chart.
- Client Connections table - contains the list of all the client connections along with their detailed information for the selected timestamp.
- Top Applications - that shows top ten applications with highest data usage. You can select an app from the drop-down list given on the top left corner of the table. Along with the selected application name it displays application specific data consumption.
- All Application traffic - it displays the total amount of data used by the applications for a selected Access Point or a location. This information is shown at the top-right corner of the table.
- Client Connections - selecting client connection displays the list of all the clients using the application selected from the top applications list.
- Access Points Distribution - selecting access points distribution displays the list of all the associated APs.
Set Data Rate and RSSI Threshold for Folder or Floor
Thresholds are global settings and can be configured only on the root folder. You must be a Superuser, Administrator, or Operator to set the thresholds. If you have the Viewer privileges, you can only view the thresholds. The same threshold values are applicable on all the folders and floors in the Navigator.
Threshold Name | Values |
---|---|
Data Rate | 20 Mbps to 100 Mbps
For example, if the threshold value is 80, clients below the set Data Rate threshold will be classified as Low Data Rate clients. |
RSSI | -45 dBm to -75 dBm
For example, if the threshold value is -60, the clients below the set RSSI threshold will be classified as Low RSSI clients |
- Go to .
- Ensure that you are in the correct folder or floor in the Location tree.
- Click Set Thresholds.
- On the Set Thresholds page, type the values for Low RSSI and Low Data Rate, within the allowed range.
- Save the settings.
Applications Dashboard
The applications dashboard gives you the quality of experience of each monitored application. You get an overall view of top ten applications that have maximum traffic in your network. The baseline gives you an insight into the percentage of poor application experience over a period of time.
Application Experience
Navigate to Dashboard > Applications to view the Application Experience chart. You can monitor the performance of web-based enterprise applications (such as Email applications, HR and Project Management applications, Intranet, Online Drive, and others) along with VOIP-based applications such as Zoom, Hangouts, and others. Arista APs capture essential details of the TCP flows of a web application and send it to the server to determine the health of the application. If the overall health is calculated as poor, CV-CUE displays the percentage of application experience for the duration. A lower percentage indicates a poor application experience whereas a higher percentage indicates a good application experience.
- Web applications running on UDP are not supported for Web Quality of Experience (QoE).
- The algorithm only inspects information carried in the IP and TCP headers for each TCP stream that are related to the monitored applications. It does not inspect the user's data in the process.
- Only Wi-Fi 5 and higher APs support QoE monitoring of web-based applications.
By default, the most affected or most used applications are shown in a card view in the Application Experience widget.
tab. If you have a preference for specific applications, you can also pin them to the![](/assets/images/user-manual/ug-cv-cue/Graphics/Dashboards/application%20exp.png)
In each card, the red bar indicates the percentage of poor application experience, whereas the green bar indicates the percentage of good application experience. If we take the case of Google APIs and Youtube in the above image, the Google API users faced poor application experience 56% of the time, whereas the YouTube users faced poor application experience 30% of the time.
You can also view the application health for a specific SSID using the SSID filter (It is set to “All SSIDs” by default). Select All SSIDs to see a graph of the aggregated data for all SSIDs and all applications.

![](/assets/images/user-manual/ug-cv-cue/Graphics/Dashboards/Clients%20by%20App%20Exp%20Widget%20-%20meet.png)
Logical Categorization of Clients and Failures
CV-CUE creates logical categories of clients, grouping them based on properties such as their band of operation (2.4, 5, or 6 GHz), OS type, etc. You can then drill-down from Client Journey and troubleshoot issues based on these client properties - for example, you can check if Association failures occurred for clients on a particular band. The grouping of clients into meaningful logical categories speeds up Root Cause Analysis (RCA) of client connectivity issues. You no longer need to spend time trying to extract patterns from a row-column grid of data.
- OS Type - The client operating system type, e.g. Android, iOS.
- Protocol / Band - The 802.11 protocols or bands the client is operating on, e.g. b/g, ac.
- Manufacturer - The client manufacturer, e.g. Apple, Samsung.
- Sticky Status - Indicates if it is a "sticky client", i.e., if it is connected to an AP even though it sees better signal strength from a neighboring AP.
![](/assets/images/user-manual/ug-cv-cue/Graphics/Dashboards/client%20catogerization.png)
Drill-Down by Logical Client Category
You can drill-down and analyse client Connectivity and Performance issues by filtering on logical client categories - for example, you can view all Authentication failures for Windows 10 clients.
- Go to DASHBOARD > Connectivity>Client Journey.
- Select the stage in the client journey that you want to analyse. For example, to analyse Authentication failures, select Authentication.
You will see the list of clients that failed authentication, with filter tabs for the most prominent characteristics, i.e., logical groupings. For example, the following figure shows tabs for Associated SSID,Frequency Band,Operating Systemand Capability.
- Select the characteristic (for example, logical category) by which you want to filter the list of clients. For example, to see the list of clients with WiFi 6 Capability that failed authentication, click the Capability filter tab.
- You can see the distribution of clients across logical categories by selecting the pie chart to the right of the filter tabs.
A Distribution window pane opens up, containing client details grouped by logical categories such as Manufacturer, OS Type, etc. as shown below. You can then select a category from this window to filter the list of clients by that category.
Infrastructure Dashboard
The Infrastructure Dashboard that provides an overview of the health of all managed access points (APs).
Navigate to Dashboard > Infrastruture to view the Infrastuture Dashboard.
Infrastructure Dashboard charts consider the CPU Utilization and Memory Utilization of all the APs present at a server to calculate the average CPU Utilization and Memory Utilization based on the different selected criterias. The average is used as the threshold to point out the APs that have higher than average CPU and Memory Utilization.
Note: You must have Aeris enabled on your server to leverage this feature.
With the Infrastructure Dashboard, network administrators can get the health check of all the APs installed at a particular location. In case of network failure, network administrators can use the dashboard to identify APs showing anomalous behavior. Infrastructure Dashboard also allows network administrators to take preventative and corrective actions based on the health insights. It helps them identify APs that have high CPU or memory utilization which might lead to network downtime because of reboot or panic due to high utilization.
Infrastructure Dashboard consists of the following charts:
CPU VS Memory Utilization by Access Point
![](/assets/images/user-manual/ug-cv-cue/Graphics/Dashboards/cpubymemory.png)
CPU VS Memory Utilization by Location
![](/assets/images/user-manual/ug-cv-cue/Graphics/Dashboards/CPU%20vs%20Memory.png)
![](/assets/images/user-manual/ug-cv-cue/Graphics/Dashboards/cpuaplist.png)
Access Points by CPU Utilization
![](/assets/images/user-manual/ug-cv-cue/Graphics/Dashboards/apsbycpu.png)
![](/assets/images/user-manual/ug-cv-cue/Graphics/Dashboards/apsbycpu_hover.png)
A yellow bar denotes APs having utilization more than the threshold. The threshold is calculated by the following formula.
Threshold = (mean utilization of all the APs + standard deviation *2)
APs with utilization higher than the calculated threshold are marked with the yellow bar. And all the APs with utilization of more than 80% are marked with red bar.
Access Points by Memory Utilization
![](/assets/images/user-manual/ug-cv-cue/Graphics/Dashboards/apsbymemory.png)
![](/assets/images/user-manual/ug-cv-cue/Graphics/Dashboards/apsbymemoryhover.png)
A yellow bar denotes APs having utilization more than the threshold. The threshold is calculated by the following formula.
Threshold = (mean utilization of all the APs + standard deviation *2)
APs with utilization higher than the calculated threshold are marked with the yellow bar. And all the APs with utilization of more than 80% are marked with red bar.
Trend Utilization
Trend Utilization chart depicts the trend of average CPU and Memory Utilization of all APs installed at the selected location. The trend chart shows 25, 50 and 75 percentile utilization of the APs. The trend chart uses comparative data and not the absolute data to depict percentile utilization.
![](/assets/images/user-manual/ug-cv-cue/Graphics/Dashboards/trend_utilization.png)
A change in the trend during a particular time duration can help administrators identify network issues or time frames when network congestion is highest.
