Mist Insights

SUMMARY Get a high-level view of the the events that have occurred at each site in your organization. You can adjust the view to focus on any site or device.

What Data Are Used for Insights?

The Mist Predictive Analytics and Correlation Engine (PACE) drives the Juniper Mist insights and service level experiences (SLEs). PACE collects the following data.

  • Telemetry data from:

    • Juniper wired switches.

    • Edge devices supported by Juniper Mist WAN Assurance.

    • Juniper Mist Edge devices.

  • Time to connect data from wireless clients.

  • Coverage, roaming, and throughput data from Juniper Mist APs <OR Juniper Access Points>.

  • Throughput data for network applications.

  • Dwell time and other location data from Bluetooth Low Energy (BLE) tags.

The Mist PACE analyzes and correlates this data to provide you with multiple ways to understand the experiences of users on your network. Use these insights to correct issues, make changes, and ensure a good network experience for your users.

Finding the Insights Dashboard

To view the Insights dashboard, select Monitor > Service Levels from the left menu of the Juniper Mist portal. Then click the Insights button at the top of the Monitor page.

Selecting the Context and Time Period

At the top of the Monitor page, select the context, which can be an entire site or a single device or client. In addition, select a time period, such the last 60 minutes, the last 7 days, or a date range.

Note:

The Monitor page displays data as recent as the past 60 minutes or as far back as the last 7 days. If you purchase a Premium Analytics subscription, you can access up to 3 years' worth of wireless network insights and other data. To access the information available through your Premium Analytics subscription, select Analytics > Premium Analytics from the left menu of the portal.

Layout of the Monitor Page

The page layout varies, based on the selected context and your active subscriptions. Some of the sections described below might not appear on your screen.

Map Display

Near the top of the Insights dashboard, you'll see a map.

  • If you selected a site as the context, the map shows the geographic location of the site.

  • If you selected an access point, the map displays the location of the AP within the site floorplan.

  • If you selected another context, the map displays that item's location relative to the site or geography that you select from the submenu.

Note:

If you have not set up a floorplan for your site, the map will be blank. You'll see see a grey block with the site name overlayed in white text.

Insights Timeline (Time Range)

Directly below the map, the timeline shows the data rate across the selected time period. You can drag your mouse across the graph to select a time period to zoom in on. The entire page refreshes to show the data for the zoomed-in area of the timeline.

Site Events

In the Site Events block, you can view a list of events that happened within the selected time range at the selected site. Site events apply only to site-assigned APs and RADIUS, DHCP, and DNS servers.

When you select an event from the list, the Insights dashboard shows an information summary about the event. The details link within the event display takes you to the Events page where you can investigate:

  • Event actions—Automatic actions, such as sending e-mails or SMS messages, that Mist performed as a result of this event.

  • Relevant details—Devices that were impacted, an impact map of the event, and any contributing events that PACE related to this event.

Client Events

In the Client Events block, you can view a list of all events recorded by Mist PACE for the selected site during the selected time frame. These events apply only to wireless clients such as cell phones and laptop computers. When you select an event from the list, Mist shows a summary of the event to the right of the list. If you click the blue text in the summary, you will see details about the client or the AP to which the client was connected at the time of the event.

Juniper access points (APs) have a built-in packet buffer. For certain events such as authorization failures, Mist keeps the buffer information and makes it available as a dynamic packet capture. The Client Events block shows events that have a Dynamic Packet Capture available with a small paper clip icon next to the event name. A dynamic packet capture can be a very powerful troubleshooting tool. You can download a dynamic packet capture (.pcap file) by clicking the Download Packet Capture button in the event summary.

You can filter the Client Events block by clicking the settings button ()in the upper-right corner of the block and choosing what to display.

Figure 2: Client Events Filter Client Events Filter

As you can see, Mist provides detailed filtering capabilities for client events.

AP Events

In the AP Events block, you can see a list of AP events that occurred on the selected site during the selected time frame. When you select an event from the list, Mist shows a summary of the event to the right of the list. You can apply similar filters to the AP Events block by clicking the settings button in the upper- right corner of the block.

Applications

Use the Applications block to view a list of the applications in use at the site during the selected time frame. The APs derive the application name primarily from DNS inspection. Mist displays columns of statistics for an application to the right of that application. These statistics are useful for determining how many clients used each application and how much bandwidth the application consumed.

You can click the number of clients to see a list of all the clients that were using the application during the selected time frame. An example of the Applications block is shown below.

Applications

Network Servers

In the Network Servers block you view see a list of network servers detected in a site. Mist can detect the presence of RADIUS, DHCP, and DNS servers. The data shown to the right of each server in the list can help you spot overused servers and identify those servers with the most failures. This type of data can help you proactively adjust server allocation to enhance the user experience.

Pre-Connection and Post-Connection

You'll see two graphs in the Pre-Connection block, one with DNS latency and the second with DHCP latency. These latency numbers reflect how quickly a wireless client connects to the wireless network, thus affecting the user experience.

You'll see two more graphs in the Post-Connection block, one with the number of connected clients and the second with the number of bytes sent and received. These two graphs show a picture of network attachment and performance, which could also affect user experience.

If you hover over a section of any of the graphs, Juniper Mist updates the display to provide the timestamp and relevant metrics in all the graphs, including the primary time range. With these metrics, you can see trends related to time within the network. You can get a larger view of any of the four Pre-Connection or Post-Connection graphs when you click the expand button () in the upper-left corner of the graph.

Note:

The following blocks of Mist Insights are not affected by the time range selections. We call these insights Current Values.

Current Site Properties

Use the Current Site Properties block to see information about the selected site at the current time. Along with geographic details, a device count, and the current number of connected clients, you also see a wireless coverage map. The coverage map is based on location information that you provide about the site. See the Location Services Guide for details about configuring maps and location information.

A heat map is a representation of relative signal strength. The heat map displays an AP as a green circle on the map. The number inside the circle represents the number of wireless clients connected to that particular AP. The dark red background fades to orange and yellow as the distance from the AP grows. This color change represents the change in wireless signal strength associated with each AP.

You can see a larger display of the map when you click the expand button () on the upper-right corner of the wireless signal strength map. You can filter both the small and large maps to show coverage for any available wireless band: 2.4 GHz, 5 GHz, or 6 GHz.

Current WLANs

In the Current WLANs block, you can see wireless LANs configured for the selected site. You can also see the number of APs in the site that host the listed WLAN, the number of clients currently connected to each WLAN, and a summary of traffic and security. When you click on any of the listed WLANs, you can view the WLAN configuration on the configuration page for the WLAN.

Access Points

In the Access Points block, you can see the names of all APs associated with the selected site. Along with the AP name, you can see the connection status, MAC address, uptime, and other information. When you click the name of the AP, the configuration page for that AP appears, where you can view and edit the configuration details.

Clients

You can use the Clients block to see a list of connected clients at the selected site. You can also view offline clients by changing the view to Total. Among the information displayed in the client block is MAC and IP address, device type, and wireless band. When you click on a client name, Juniper Mist takes you to the Client Insights page for that client.

Wired Switches

In the Wired Switches block, you can see a list of EX Series switches associated with the selected site. Summary information includes the switch name, model, IP address, and Junos version information.
