The SD-WAN Center Dashboard
Sep 21, 2017
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.
- Network Map
- Top Application and Top Application Families
- Network HDX: Quality Summary
- Network HDX: Users and Sessions
- Network HDX: Bottom 5 Sites
- Site HDX: Users
- Site HDX: Sessions
- Site HDX: QoE
- Network Health: Virtual Path Report
- Current Events
- Inventory Manager
- SD-WAN Center: Alarm Summary
- SD-WAN Center: Database Usage
- SD-WAN Center: Active OS Usage
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.
Top Applications and Top Application Families
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.
Network HDX: Quality Summary
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.
Network HDX: Users and Sessions
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.
Network HDX: Bottom 5 Sites
This widget provides a list of the bottom 5 sites that have the least scoring QoE to help drive better end-user experience initiatives.
Site HDX: Users
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.
Site HDX: Sessions
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.
Site HDX: Quality of Experience
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:
- Site: Name of the site found in the configuration running in the MCN. If the appliance is a secondary MCN, “(secondary)” appears next to the name. The name is a link to connect to the appliance management web console.
- Connection Status: Connectivity state to the appliance. A red icon appears when the connection is not reachable or not authenticated.
- Management IP: Management IP address of the appliance. The IP address is a link to the appliance management web console.
- Model: Hardware model of the appliance
- Serial Number: Serial Number of the appliance.
- BIOS Version: BIOS version of the appliance.
- Days Since Memory Dump: Time since last system-error memory dump. If the appliance dumped its memory in the past 4 days, an error icon appears next to the time. If the memory dump occurred between 5 and 10 days ago, a warning icon appears. N/A appears if no dump is available. Clicking on the time opens the log page of the SD-WAN.
- Active OS: The OS currently running on the appliance.
- Backup OS: The OS on the appliance’s backup partition.
- RAM Size (GB): Amount of Random Access Memory currently installed on the appliance in GB.
- Drive Type: Type of data-storage drive installed on the appliance. The value can be SSD (Solid State Drive) or HDD (Hard Disk Drive).
- Drive Size (GB): Size of the data-storage drive currently installed on the appliance in GB.
Network Health: Virtual Path Report
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.
SD-WAN Center: Alarm Summary
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.
SD-WAN Center: Database Usage
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.
- Usage: Database capacity currently being used, in GB.
- Notification: Threshold for generating a database usage notification. The threshold is a percentage of the maximum size of the database. If an email alert is configured, an email notification is sent when the size of the database exceeds this threshold. For more information, see Setting Notifications.
- Stop Polling: Threshold for halting statistics polling. The threshold is a percentage of the maximum size of the database. Polling stops when the size of the database exceeds this threshold.
For more information, How to Manage Database.
SD-WAN Center: Active OS Usage
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.
