WAN Edge Health SLE

What Does the WAN Edge Health SLE Measure?

Juniper Mist monitors the user minutes when the health or performance of the WAN edge device is not optimal. Suboptimal health lowers the device's ability to pass traffic, thus directly affecting any clients connected to the device.

Juniper Mist analyzes various factors that affect WAN edge health and assigns a score. You can click the Settings button to set the success threshold.

Classifiers

When the WAN Edge Health threshold is not met, Juniper Mist sorts the issues into classifiers. The classifiers appear on the right side of the SLE block. In this example, 100 percent of the issues are attributed to CPU. (See the classifier descriptions below the example.)

• • Memory—Juniper Mist triggers this classifier when the WAN edge memory utilization is above 80 percent.

  • Power—Juniper Mist triggers this classifier when power consumption is above 90 percent of the available power.

  • WAN Edge Disconnected—Juniper Mist triggers this classifier when the WAN edge device disconnects from the Juniper Mist cloud.

  • Temp—Juniper Mist triggers this classifier when the operating temperature of the WAN edge device exceeds the prescribed threshold range, either going above the maximum limit or below the minimum requirement.

    • CPU—Juniper Mist triggers this sub-classifier when the CPU temperature exceeds the prescribed threshold range.

    • Chassis—Juniper Mist triggers this sub-classifier when the chassis temperature exceeds the prescribed threshold range.

  • CPU—Juniper Mist triggers this classifier when the CPU utilization is above 90 percent. When the CPU utilization spikes on a Juniper WAN edge device, downstream devices can lose their connectivity. Therefore, clients fail to pass traffic.

    • Data Plane—Juniper Mist triggers this sub-classifier when the Data Plane CPU utilization is above 90 percent.

    • Control Plane—Juniper Mist triggers this sub-classifier when control plane CPU utilization is above 90 percent.
