Mist Insights

The Insights tab on the Monitor > Service Levels page provides a high level view of the events that occurred over a specific time period within a selected site in your organization.

Site Insights

In the Juniper Mist portal, the Insights tab on the Monitor > Insights Service Levels page provides high-level awareness of what is happening in your network. The Mist Predictive Analytics and Correlation Engine (PACE) drives the Juniper Mist insights and service level experiences (SLEs). The information that Mist PACE collects includes:

  • 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. You can use the Mist PACE results to correct issues, make changes, and ensure a good network experience for your users.

You can change the context of the displayed insights from an entire site to individual access points (APs) or clients by selecting the option from the context menu. In addition, you can filter to only view insights for the last 60 minutes through the last 7 days.

Figure 1: Insights Dashboard with Options Insights Dashboard with Options

When you navigate to Monitor > Service Levels, you see the Insights dashboard. The first time you navigate to this page, the Insights tab is selected by default. Also by default, the context menu is set to a site within your organization (site context). A search field is available in the context menu regardless of which context you select. When the context menu is set to Site, the Insights dashboard displays the following sections below the timeline:

  • Site Events—Site events include information about Domain Name System (DNS) or Dynamic Host Configuration Protocol (DHCP) server reachability or AP reboot events.

  • Client Events—Learn about events that are related to or reported by individual client devices. The reporting clients can be wired or wireless. For example, a client event occurs when a client's DNS request fails.

  • AP Events—Determine events that are related to or reported by a AP. For example, you may experience an AP event when the configuration of an AP changes.

  • Applications—Discover the network applications that are running on your network. The application insights that this section provides include the percentage of traffic using a given application and the total bytes of data on the network for each application.

  • Network Servers—Get success or failure information for three network server types: RADIUS, DHCP, and DNS.

  • Pre-connection and Post-connection—Know how long it takes for a wireless client to connect to the network. Use these insights to determine the connected client count and amount of data sent and received.

  • Current Site Properties—Know more about the site location properties, including information about the current count of devices and clients.

  • Current WLANs—View the count and names of all wireless LANs (WLANs) defined on your site along with information for each wireless LAN.

  • Access Points—Get the current status information about all access points configured at the site.

  • Clients —Discover information about the count, name, and types of wireless clients associated with the current site.

  • Wired Switches—Know about any wired switches associated with the site. The information includes the switch name, the IP address, and a count of APs connected to the switch.

Note:

The sections displayed on the Insights page depend on the subscriptions you have licensed. The list above represents the sections available for a fully licensed organization.

Throughout this topic, we describe the features and screens available to a fully licensed organization. If you have purchased only a Wireless Assurance license, then Juniper Mist displays only the Wireless and Insights tabs on the Monitor > Service Levels page.

Context Menu

The context menu lets you select the context for the dashboard display. You can select one of the following contexts from the context menu:

  • Site

  • Access Point

  • Client

  • Switch

  • WAN Edge

  • Wired Client

  • Mist Edge

  • Cellular Edge

Site is the broadest context available. You can select any site that you've configured within your organization. The default is your primary site or the first site that you created. You can search for a site by its name if you have a large number of sites.

You can use the remaining context options to see insights for specific devices or clients. By default, the submenu displays the APs, clients, switches, and other network devices associated with the primary site. If you select a different site, the submenu displays the APs, clients, switches, and other network devices associated only with that site. You can change the site context by selecting a specific site name or Any Site from the submenu.

Alternatively, you can search within the submenu for devices or clients by name or MAC address that are related to the selected site.

Map Display

The Insights dashboard displays a map directly below the tabs. The context that you select in the context menu determines the map that the dashboard displays. If you select Site, the map shows the geographic location of the site. If you select Access Point, the map displays the location of the AP within the site map. When you select any other 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 map of your site location, the map will be blank—you will see a grey block with the site name overlayed in white text.

Insights Timeline (Time Range)

The time range graph that appears directly below the map displays only today's events by default. You can pull down the Today menu to change the time range display. As mentioned previously, you can zoom the display in as close as the last 60 minutes or zoom the display out as far as the last 7 days.

You can change the time range to display Site Events, Client Events, or AP events by clicking the appropriate blue text in the time range.

If you purchase a Premium Analytics subscription, you can access up to 3 years' worth of wireless network insights and other data. You can see the data for a longer time range only through the Premium Analytics interface, not on the Monitor > Service Levels > Insights dashboard.

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.
