Viewing AP Health Indicators

You can monitor the AP performance and connection failures at the domain, zone, AP group, or specific AP level from the Health tab on the Access Points page. For all health metrics, the maximum, average, and minimum values are displayed for the AP group, followed by the specific value for each of the top APs. You can customize the number of individual APs displayed for the selected domain, zone, and AP group.
AP health indicators are divided into two categories: Performance and Connection Failure.

Performance

  • Latency - It is the measurement of average delay required to successfuly deliver a Wi-Fi frame.
  • Airtime Utilization - It is a measurement of airtime usage on the channel measuring the total percentage of airtime usage on the channel.
  • Capacity - It is a measurement of potential data throughput based on recent airtime efficiency and the performance potential of the AP and its currently connected clients.

Connection Failure

  • Total - It is a measurement of unsuccessful connectivity attempts by clients.
  • Authentication - It is a measurement of client connection attempts that failed at the 802.11 open authentication stage.
  • Association - It is a measurement of client connection attempts that failed at the 802.11 association stage, which happens before user/device authentication.
  • EAP - It is a measurement of client connection attempts that failed during an Extensible Authentication Protocol (EAP) exchange.
  • RADIUS - It is a measurement of RADIUS exchange failures due to AAA client/server communication issues or errors
  • DHCP - It is a measurement of failed IP address assignment to client devices.
  • User Authentication - It is a measurement of post authentication attempts that failed at the application layer such as Web Authentication, Guest Access, and Hotspot (WISPr) login.

    Viewing Connection Failure

You can customize the information displayed in the Performance and Connection Failure section:

  1. From the Access Points page, select the required domain, zone, AP group, or AP.
  2. Scroll down and select the Health tab.
  3. On the Performance bar, select the Setting icon. The Settings - Performance pop-up appears. Customize the following:
    • Show top: Enter the top number of APs for which you want to see all three Performance metrics (default is 10). When you select a domain or zone from the network heirarchy, the Show top field filters the display to only the top number of APs that you specified in that domain or zone.
    • Display Channel Change: Select the required options. For example: 2.4G, 5G, and 6G/5G.

      This option is available only when a single AP is selected.

    • AP: Choose the unique identifier displayed for each AP. For example: Name, MAC, IP.
  4. Click OK.
    You can also customize the Performance metrics display using the following:
    • Historical Health versus Real Time Health view drop-down list (this option is available only when a single AP is selected; when a domain or zone is selected, the only view available is Historical Health).
    • The Last 1 hour versus Last 24 hours drop-down list (The vSZE and SZ144 web interfaces additionally have Last 7 days and Last 14 days options).
    • The radio band drop-down list.
    Performance details of the AP are listed according to the settings.
  5. On the Connection Failure bar, select the Setting icon. The Settings - Connection Failure pop-up appears. Customize the following:
    • Show top: Enter the top number of APs for which you want to see all three Performance metrics (default is 10). When you select a domain or zone from the network heirarchy, the Show top field filters the display to only the top number of APs that you specified in that domain or zone.
    • AP: Choose the unique identifier displayed for each AP. For example: Name, MAC, IP.
    You can also customize the Connection Failure metrics display using the following:
    • The Access Points versus Failure Types drop-down list.
    • The Last 1 hour versus Last 24 hours drop-down list (The vSZE and SZ144 web interfaces additionally have Last 7 days and Last 14 days options).
    • The radio band drop-down list.
    Connection Failure details of the AP are listed according to the settings.
