Alert Configuration

SUMMARY Learn about alert configuration in the Juniper Mist dashboard.

Alerts Overview

In Juniper Mist, alerts present those events that don't fit neatly into the service-level experience (SLE) model. Whereas SLEs represent events that have already happened, alerts represent network and device issues that are ongoing. On the Monitor > Alerts dashboard, you can see three types of alerts: Infrastructure, Marvis, and Security. 

Juniper Mist categorizes alerts that can potentially affect a large number of clients as infrastucture alerts. For example, an event during which a Domain Name System (DNS), Dynamic Host Configuration Protocol (DHCP), or RADIUS server is unreachable can affect many clients.Similarly, if a power supply on a switch is in alarm state, a large number of clients and a large amount of traffic could be affected.

The Mist Predictive Analytics and Correlation Engine (PACE) raises Marvis alerts for the events that Marvis tracks. For example, if an access point (AP) regularly fails health checks, Marvis notices and tracks this event.

Security alerts are raised by repeated events that could dramatically affect network security. For example, if a rogue AP is detected, that represents a potential security problem and if a client connects to a rogue AP, that could be even worse.

We rank each category of alert by severity:

Table 1: Alert Severity
Severity Indicator Recommended Action
Critical Red dot Take immediate action.
Warning Orange dot Continue monitoring if the event continues.
Informational Blue dot No action is required.

In the image below, you can see an example of the Juniper Mist Alerts dashboard.

You can use the drop-down lists at the top of the Alerts dashboard to filter the dashboard display by:

  • Site—You can choose to see alerts from your entire organization or from any site for which you have viewing rights. You can search within the menu for specific sites by name.

  • Date—You can choose to see alerts from a specific date or time, or for a time range—from 60 minutes through 7 days.

Alert Configuration

When you click the Alerts Configuration button, you can view and configure Juniper Mist alerts. You can configure alerts on an organization-wide basis or on a site-by-site basis. You can enable or disable any alert by selecting or clearing the check box, respectively, next to the alert name. You can elect to have an e-mail notification sent to organization or site administrators, or to a comma-separated list of e-mail addresses. You can see an example of the Figure 1 page below.

Figure 1: Alert Configuration

In the Figure 1 image above, you can see:

  • The alert configuration scope is set for the entire organization.

  • E-mail notifications, if enabled, are configured to go to organization and site administrators.

  • All the alert types belong to the Infrastructure category.

  • None of the alert types are configured to send e-mail notifications.

  • The critical DNS Failure, DHCP Failure, and DNS Failure alerts each have an edit (pencil) icon, which indicates that you can configure the threshold for each of these alerts.

  • The informational Critical Switch Port Up and Critical WAN Edge Port Up alerts have an information (i in a circle) icon, which indicates that you must perform additional configuration to enable these alerts.

The two icons that indicate additional configuration options for alerts appear only for certain alerts in the infrastructure category. No alerts in other categories have additional configuration options.
