View WAN Edge Insights for Monitoring

WAN Edge Insights

From the left menu of the Juniper Mist portal, select WAN Edges > WAN Edges, then select your WAN Edge device.

In the Properties pane, select WAN Edge Insights for the next level of information about your WAN Edge device.

Next to the selected WAN Edge on the Insights page, you can select the time frame for which you want to view the information. The default view is Today, but this can be set to a customized date, or range of dates. Below this, you find (when the site location information is configured) where this WAN Edge is configured via a street map.

• WAN Edge Events
• Table Capacity

With your time frame selected, WAN Edge Events displays a time line of the traffic through the WAN Edge during your specified time, and provides a list of events.

Select a specific event in the listed WAN Edge Events for greater detail of the Total, Good, Neutral, and Bad events. Detailed information about the event displays on the right based on what you selected.

To drill down to a detailed portion of time, select a window of time with your mouse cursor. By doing this, you’re able to adjust the window of events and isolate specific Good, Neutral, and Bad occurrences that happened on your network. With a smaller section, you’ll get a more detailed view of that period.

Scroll down on the WAN Edge Events page for deeper insights within your selected period.

In the WAN Edge Events section, you can narrow down the type of event by selecting a modifier from the drop-down menu. You can also filter your search by limiting the event types to a specific port.

The Table Capacity section provides you with quick access to the Forwarding Information base (FIB) tables and Session tables for each node of your device:

• FIB Entries: Displays the current number of FIB entries and the percentage of utilization; essentially showing how much of the available FIB space is currently being used.

• Session Flows: Displays the current number of active sessions and the percentage of session flow utilization based on the device's capacity.

In the case of a high availability cluster, Table Capacity indicators are displayed for each node.

Click the Search Entries button under each metric to open a shell view in a new window. In this view, users can search for entries after specifying filters.

Applications

The Applications section of the Insights page lets you view reports on applications. It is divided into four tabs (Categories, Apps, Applications, and Clients). This section allows you to:

• Use categorized applications to monitor and troubleshoot specific application behavior.
• View a client's use of a particular application by clicking the Clients tab.

On the Categories tab, you can see the following details about applications usage:

Table 1: Applications (Columns)

Column	Description
Category Name	The category of the applications. Expand the categories to view individual applications details.
Number of Clients	Click on the number to see more information about the clients using the application.
Total Bytes	The traffic volume that each application or website receives and transmits.
Percent Bytes	Percentages of traffic volume that each application or website receives and transmits.
RX Bytes	Traffic that applications or websites receive.
TX Bytes	Traffic that applications or websites transmit.

Note:

Ensure you’ve had a few hours for these metrics to be populated following initial deployment.

On the Categories tab, in the Number of Clients column, you can click on the number to see more information about the clients using the application.

Note:

For WAN Edge devices running a DHCP server, clients using that application will display a HostName in the Client column if available. Otherwise, the MAC address will be displayed. Device Type and MAC Address columns will be populated as well.

In the Apps tab, hover over the App Name to see more details about the services.

Use the Applications tab to monitor and troubleshoot specific application behavior.

Click the Clients tab to see how much bandwidth a particular client is using, as well as a client's usage of a particular application. You can click the number in the Number of applications column to see more information regarding the client's application use.

Application Path Insights (BETA)

The Application Path Insights (BETA) section displays which applications are using the most bandwidth according to the selected Application Policy and Network. It displays the effective application flow over the path for the selected Application Policy.

You can also change the Data Type to Sessions to see the number of sessions occurring per application. Hover over a section of the graph to view the bandwidth or sessions per application as well as jitter, loss, and latency.

Note:

The Application Path Insights visualization data is available only if the configuration is managed by Juniper Mist.

The path state bar shows path state information over a time line, and path state events are indicated by segments highlighted in different colors. For example, Path Up events are shown in green, and Path Down events are shown in red.

You can filter this section in the following ways:

• Policies: You can filter by policy type.
• Data Type: Toggle between Bandwidth and Sessions to analyze traffic volume or session count.
• Networks: Filter by specific networks.

A list of applications is shown with color-coded tags.

You can hover over the highlighted portions of the path state bar to view a summary of path state events.

If you click on the bar, a pop-up window displays containing detailed information about the path state events. The list of events displays on the left and when you select an event, the reason for the event displays on the right.

WAN Edge Device Charts

The WAN Edge Device Charts include Control Plane CPU, Data Plane CPU, Memory Utilization, and Power Draw (SRX Only).

The Control Plane CPU and Data Plane CPU charts show you the percentage of CPU utilization for both max and average. On the Control Plane CPU, you can click the View Live Process Detail link to see more in depth information about the processes that are running on the control plane.

The Memory Utilization and Power Draw (SRX Only) charts show you the percentage for both max and average.

WAN Edge Ports Charts

The WAN Edge Ports charts include Bandwidth, Max Bandwidth, Applications TX + RX Bytes, Port Errors, and IPsec Traffic (SRX Only). From the drop-down list at the top, you can select All ports to see utilization metrics for all interfaces, or you can select an interface to see the metrics for that particular interface.

• In the Bandwidth chart, the bandwidth utilization metrics in megabits per second (Mbps) for that particular interface display.
• The Max Bandwidth chart displays insights into the highest point of link utilization recorded for received power signal (RX) and transmitted power signal (TX) packets on each port during the day in Mbps.

The last three WAN Edge Ports charts are Applications TX + RX Bytes, Port Errors, and IPsec Traffic. Hover over the charts to find out more information.

• The Applications TX + RX Bytes chart outlines transmit and receive data information, which can be isolated at an application level by clicking on the application name at the bottom to see Client, MAC address, IP address, device type, bytes, and % bytes for bandwidth utilization.

• The Port Errors graph displays port errors detected on the WAN Edge device over a period of time. Port errors are Ethernet data link error counts that include all possible Ethernet errors reported by the port device driver. Exact types of errors vary by device driver, and the total may include but is not limited to CRC errors, collisions, and so on. Errors are counted in both the transmit (TX) and receive (RX) direction. The graph displays the total for all ports, or for a particular port based on the WAN Edge Ports selection.

• The IPsec Traffic chart displays IPsec traffic for transmit and receive packets during the day in kilobytes or megabytes.
