Issue/Introduction
This article covers several features on the VMware SD-WAN Orchestrator features that a user may use for monitoring their Edges. This includes the ability to gather information on application usage for an Edge.
Environment
VMware SD-WAN by VeloCloud
Resolution
On the VMware SD-WAN by VeloCloud Orchestrator, the Monitor->Edges navigation panel monitors WAN links and displays usage data via network sources and traffic destinations.
The Edges monitoring screen includes the following tabs:
1. Overview: this tab displays information about WAN links, application bandwidth, and network usage for top operating systems, top categories, and the top sources and it consists of two major areas: Link Status and Bandwidth Usage:
Note: The time periods covered in those statistics can be adjusted in the drop down menu that begins "Past <time period>". The default setting is "Past 12 Hours" and may be adjusted to as little as 60 minutes and as much as a week.
In the Link Status area, the Cloud Status and VPN Status columns can display the following link status:
Green = Active/Stable
Gray = Not enabled/Dormant
Yellow =Unstable
Red = Offline/Disconnected
You may observe the status of WAN links that are configured as backup (per the Configure->Devices->WAN Settings tab):
The VQS rates an application's quality of experience that a network can deliver for a period of time. QOE displays the best tunnel statistics out of all tunnels from the Edge. In a future release, we will improve this by supporting per path visibility.
Traffic Type: there are three different Traffic Types that you may monitor: Voice, Video, and Transactional. Note: the default traffic type is Voice.
You can hover over a WAN network link, or the aggregate link (marked as "After") provided by VeloCloud to display a summary of Latency, Jitter, and Packet Loss.
VeloCloud Quality Score (VQS): VQS rates an application category (voice, video, or transactional) for the expected quality of experience that a network can deliver for a given time frame. QoE rating tiers are shown in the table below.
3. Transport: this tab provides an overview of the bandwidth used across each of the WAN links. You can hover over the line graph and view Sent and Received data in a pop-up window.
For any point in time, you can view which Link or Transport Group was used for the traffic and how much data was sent. See the sections below for a description of the major areas of the Transport tab.
5. Sources: This tab displays network usage data (operating system, device type) over a historical period of time sorted by the client device sending the traffic.
The data is displayed as two line graphs. You can change the data that is displayed in the graphs from the Data drop-down menu (Bytes Received/Sent, Total Bytes, Total Packets, or Packets Received/Sent). You can also hover over a segment of the graph to display the source and its associated network usage.
In the Sources tab screen (below image), you can:
Destinations: This tab displays network usage as two sets of line graphs (sent and received) sorted by the destination of the network traffic. If you hover over a segment of the graph, the destination and its associated network usage appears.
There are three display buttons (Domain, FQDN, and IP) located on the right side of the screen. Click one of the display buttons to update destinations by type in the Destination column.
The Edges monitoring screen includes the following tabs:

In the Link Status area, the Cloud Status and VPN Status columns can display the following link status:
Green = Active/Stable
Gray = Not enabled/Dormant
Yellow =Unstable
Red = Offline/Disconnected
You may observe the status of WAN links that are configured as backup (per the Configure->Devices->WAN Settings tab):
The Link Status area displays a list of all links that have been active for the listed time period. This display includes Cloud and VPN status, the Edge Interface the link uses, and Throughput Capacity.
With the Links Status feature:
- You may view a list of your links and their status: (Green=Connected, Gray = Not enabled/Dormant Red=Not connected; Yellow=Unstable; ).
- You may view real time Latency, Jitter, and Packet Loss by clicking the arrow next to the Signal column.
- You may view link data updated in real time.
The VQS rates an application's quality of experience that a network can deliver for a period of time. QOE displays the best tunnel statistics out of all tunnels from the Edge. In a future release, we will improve this by supporting per path visibility.
Traffic Type: there are three different Traffic Types that you may monitor: Voice, Video, and Transactional. Note: the default traffic type is Voice.

3. Transport: this tab provides an overview of the bandwidth used across each of the WAN links. You can hover over the line graph and view Sent and Received data in a pop-up window.
For any point in time, you can view which Link or Transport Group was used for the traffic and how much data was sent. See the sections below for a description of the major areas of the Transport tab.
Links: is the default display screen (as shown in the image above). The Links screen displays Sent and Received data for your links regardless of type. Any links associated with an Edge are displayed in a numbered list at the bottom of the screen under the Link column, along with their Interface (WAN Type) and Bytes Received/Sent. See image above.
Note: Bytes Received/Sent is the default throughput measurement for the Transport screen. Alternate measurements include--Average Throughput; Total Bytes; Packets Received/Sent; and Total Packets and are selected in the drop-down menu on the upper left of the graph.
The Links screen displays:
- Status for Cloud and VPN ((Green=Connected, Gray = Not enabled/backup Red=Not connected)
- Link Info (you can access this pop-up window by clicking the down arrow next to Interface WAN Type)
- Applications (click the gray arrow underneath the Application column)
Network Usage is displayed as one or two graphs (depending upon the type of data you choose) with an option to scale the Y-axis. You can hover over a segment of the graph to display network usage data for that segment.
Top applications: To display specific application data in the graphs, select or unselect the checkboxes next to the applications in the Applications column. You can also click an application in the Applications column to open a dialog box, which displays all applications in a Pie chart
In the Top Applications dialog box (as shown in the image below), you can:
- Click an application name (or its color-coded slice of the Pie chart) to view its Transport Groups, Top Operating Systems, and Top Destinations.
- Click the arrow next to the Top Devices area to open the Sources tab.
- Choose an option from the drop-down menu in the Top Destinations section (by Domain, by FQDN, or by IP).
- Click the arrow (top, right corner) of the Top Destinations area to open the Destinations tab.
5. Sources: This tab displays network usage data (operating system, device type) over a historical period of time sorted by the client device sending the traffic.
The data is displayed as two line graphs. You can change the data that is displayed in the graphs from the Data drop-down menu (Bytes Received/Sent, Total Bytes, Total Packets, or Packets Received/Sent). You can also hover over a segment of the graph to display the source and its associated network usage.
In the Sources tab screen (below image), you can:
- View the operating systems of your applications and destinations in the Operating Systems column (located at the bottom of the screen).
- Use Filter to display operating systems based on Application, Category, type of Operating System, and Destination.
- Click an operating system from the Operating System column to open the Top Operating Systems dialog box.
- Go to the Applications tab by clicking the gray arrow next to the Top Applications area of the Top Operating Systems dialog box.
- Go to the Destinations tab by clicking the gray arrow next to the Top Destinations area of the Top Operating Systems dialog box.
Destinations: This tab displays network usage as two sets of line graphs (sent and received) sorted by the destination of the network traffic. If you hover over a segment of the graph, the destination and its associated network usage appears.
There are three display buttons (Domain, FQDN, and IP) located on the right side of the screen. Click one of the display buttons to update destinations by type in the Destination column.
For each display button (Domain, FQDN, and IP), the Top Destinations dialog box appears by type when you click a destination from the Destination column. You can open the Applications and Sources tabs from the Top Destinations dialog box. Click the gray arrows next to the Top Applications and Top Devices (Sources) areas of the dialog boxes to open each of these tabs.
