    For Switch CPU Utilization and Switch Memory Utilization alerts, the Root Cause section highlights the top five processes responsible for high utilization.

    Note: CPU utilization for processes is measured per CPU core. Since AOS-CX switches have multiple cores, the overall CPU utilization for a process can exceed 100%.
  • Actions card—The Actions card provides recommendations to address the warning. These recommendations are generated using AI algorithms designed to optimize network configurations and suggest performance enhancements.

    Figure 10: Actions Card

    For alerts such as Interface CRC Errors, Port Flaps, and AP Connected at 10/100 Mbps, you can perform a Cable Test to determine if a faulty cable is causing the issue. To run a cable test, perform the following steps:

    1. Click the icon to view the expanded Actions page.

    2. Under Actions, click the Cable Test button.

      The results of the cable test are displayed. You can click the Troubleshoot icon to view the details on the Troubleshoot page. Alternatively, you can navigate to the Alerts Dashboard and locate the Troubleshooting card to review the results.

Alert History Card

The Alert History Card provides a graphical representation of the trend of the primary Key Performance Indicator (KPI) that triggered the alert over time. This card helps users understand when and why the alert was issued.

The card displays one of the following types of graphs based on the triggering mechanism:

  • Alerts Triggered by a Threshold

    These alerts are triggered when the primary KPI exceeds a defined threshold.

    Figure 16: Alerts Triggered by Threshold Chart

    The y-axis represents the primary KPI, while the x-axis represents the timeline. Hover over the graph to view details including the date and time, alert severity, the reason for the alert, the KPI value at that time, and the defined threshold value.

  • Alerts Triggered by a Baseline

    The alert is triggered when the primary KPI deviates by a specified percentage above or below the baseline.

    Figure 17: Alerts Triggered by Baseline Chart

    The y-axis represents the primary KPI, while the x-axis represents the timeline. Hover over the graph to view the baseline band and a tooltip showing the date and time, alert severity, the reason for the alert, the KPI value at that time, and the baseline range.

  • Alerts Triggered by Change in State

    The alert is triggered when the primary KPI's state changes for a defined period of time.

    Figure 18: Alerts Triggered by Change in Status

    The y-axis represents the status of the primary KPI, while the x-axis represents the timeline. Hover over the graph to view the date and time, alert severity, the reason for the alert, the KPI value at that time, and the state change.
