The SD-WAN Center Dashboard displays a subset of the common statistics at a glance. The application and site specific statistics are obtained from the MCN that is discovered in the SD-WAN Center. The following widgets are available on the Dashboard.
All the widgets are displayed on the dashboard by default. You can customize the dashboard by closing the widgets that you do not want to view and by arranging the widgets as per your requirement. To view all the widgets as per the default settings, click Reset Dashboard.
The SD-WAN Center Dashboard is refreshed based on the configured polling interval. The default polling interval is 5 minutes. For more information see, How to Configure Polling Interval.
The network map provides a graphical view of the SD-WAN network. The information displayed in this section is updated depending on the selected configuration and routing domain. In order to view a network map here, you must import the network configuration and Network maps from the Master Controller Node (MCN). For more information, see How to Import Network Configuration from MCN to SD-WAN Center.
Deep packet inspection (DPI) allows the SD-WAN appliance to parse the traffic passing through it and identify the application and application family types. The top results of the parsed traffic is displayed in this widget.
The SD-WAN Center dashboard displays the top applications and top application families. You can select the site and time interval as last 24 hours, last 1 hour, or last 5 minutes.
Qauality of Experience ( QoE) is a calulated index that helps you understand your ICA quality of experience. This index is calculated for all ICA application traffic traversed from WAN to the site. Statistics of packet drop, jitter and latency are used in the QoE calculation. The QoE is an integer between [0, 100], the higher the number, the better the user experience. The jitter, latency and packet drop statistics are tracked on data paths during packet processing.
Sites in the entire network are categorized as good, fair, poor or no HDX traffic based on the QoE of HDX traffic. . For more information, see Application QoE.
The HDX traffic is classified into the following three quality categories:
No HDX Traffic
You can click on the chart to view HDX reports per site. For more information, see How to View HDX Reports.
Sometimes, the HDX dashboard data and HDX reports from different sites may not seem to be in sync because each site statistics are polled independently. The out of sync could happen when some sites stats are polled and refreshed but other sites are not polled yet.
On HDX dashboard widgets, you may see a site with no HDX traffic, but there may be a non-zero number of HDX sessions and users. This could happen when the HDX sessions remain idle for that polling period, and still stay in open state.
This widget provides information on the number of active HDX users and sessions. The number of sessions is the total number of active Single Session ICA (SSI) and Multi Session ICA (MSI) sessions.
In the current release, the number of users is not based on distinct user names. That is, two sessions started by a single user on two different machines is counted as two users.
This widget provides a list of the bottom 5 sites that have the least scoring QoE to help drive better end-user experience initiatives.
This widget provides a graphical representation of the number of users that were active at a particular site for the selected time interval. You can select the site and the time interval as last 24 hours, last 1 hour, or last 5 minutes.
This widget provides a graphical representation of the number of MSI and SSI sessions that are active at a particular site for the selected time interval. You can select the site and the time interval as last 24 hours, last 1 hour, or last 5 minutes.
This widget provides a graphical representation of the overall QoE at a particular site for the selected time interval. You can select the site and the time interval as last 24 hours, last 1 hour, or last 5 minutes.
The Current Events section of the dashboard displays the events from all the discovered appliances in the network, that occurred in the last one hour. The output of events can be filtered using the Routing Domain drop-down menu. The information displayed in this section is gathered from the Fault tab. For more information, see Events.
Once every 30 minutes, the Inventory Manager gathers the hardware information collected from all the SD-WAN appliances that have been discovered by the SD-WAN Center VM. The Inventory Manager page displays this data in columns that you select and filter. The following columns are available:
The Virtual Path Reports section of the dashboard displays virtual path level statistics for every virtual path in virtual WAN network that was measured as an average over the last 24 hours. The output can be filtered based on the selected routing domain.
For more information, see Reports.
The Alarm Summary section of the dashboard gives a graphical overview of the type and quantity of events. You can click on the graph to view the events on the Fault page. The display also outlines how many events are in each category. Alarm triggers can be configured on the individual SD-WAN Appliances. For more information see, Configuring Alarms.
The Database Usage section of the dashboard displays a graphical overview of the database-resource usage and the thresholds for sending notifications or halting the collection of data. You can click on the graph to view the details on the Database Maintenance page.
The Active OS Usage section of the dashboard gives a graphical overview of the used and available storage space in GB. You can click on the graph to view the details in the Storage Maintenance page.
