Health

The Health card provides important information about the gateway, including health status, uptime, the last reboot reason, configuration status, and the latest configuration change for the last 3 hours. You can hover over the bar to see which alert changed the health metric.

Figure 1: Gateway Health Card

The following table describes the Health card parameters:

Table 1: Gateway Health Card Information

Parameter

Description

Displays the following details:

  • Status—Online

  • Health—Good (CPU usage is <70% and Memory utilization is < 90%)

Displays the following details:

  • Status—Online

  • Health—Fair (CPU and memory utilization is between 70-90% or interface error rate is > 40%)

The reason for the fair health is displayed next to this icon.

Displays either one of the following details:

  • Status—Online
  • Health—Poor (CPU usage is >70% and Memory utilization is > 90%)

The reason for the poor health is displayed next to this icon.

Or

  • Status—Offline
  • Health—Poor

The date and timestamp of when the gateway was last seen online are displayed next to this icon.

Uptime

Time since the gateway is operational without interruption.

Last Reboot Reason

Reason for the last reboot of the gateway.

Configuration Status

Displays the configuration status of the gateway as Synchronized or Unsynchronized. The configuration state will change only when the configuration is pushed from HPE Aruba Networking Central.

When the Gateway Config Sync Failure alert is generated, then the corresponding health status of the gateway is displayed in the Gateway Dashboard page.

Last Configuration Change

Displays the timestamp of the last configuration change on the gateway.

Gateway Health Computation

The gateway device and connectivity performance health is calculated based on the following considerations:

  • Severity of the alert generated for the gateway device.

  • Priority of the health metric for which the alert is generated

Note: You can configure the severity and threshold conditions for an alert on the Alert Management page. For more information, see Configuring Alerts.

The following table describes the alert severity and health status mapping:

Table 2: Alert and Health Status Mapping

Alert Severity

Health Status

Critical

Poor

Major

Fair
Minor or any severity other than Critical and Major

Good
Note:

If there is no alert generated for a gateway device, then the health is always displayed as Good.

The gateway health metrics is based on the generated alert.

  • Hardware

    • CPU 

    • Memory

Note:

The health reasons outlined above are based on alerts, while all other health reasons are determined strictly by health metrics.

For more information on the alerts generated for gateways, see Gateway Alerts.

WAN Transport Health at Site Level

The ability to view WAN Transport Health at site level provides a unified monitoring experience by consolidating WAN transport metrics, probe statistics, and uplink persona state into a single interface. It offers enhanced summary and expanded gateway views that highlight key indicators such as loss, latency, jitter, and availability, while backend APIs supply consistent, real‑time data to the UI. These capabilities allow to quickly detect degraded uplinks, compare performance across locations, and troubleshoot issues with greater accuracy and efficiency.
