Using the RF Health Report

The RF Health report assists in detecting the most problematic devices on your network, and lists the top devices by problem type. The default RF Health report shows the max concurrent clients count per radio band.

When creating a custom RF Health report, you can select the following widgets from the custom options:

  • Max concurrent clients (2.4 GHz)
  • Max concurrent clients (5 GHz)
  • Max concurrent clients (6 GHz)

From the Generated reports, you can open the monitoring page for the selected radio by clicking a hyperlink in the AP Name column.

Thresholds

Thresholds for the radio statistics are reported as a percentage (%) or a power measurement (dBm). For information on changing the threshold values, see Changing Your Report Summary and Thresholds.

Figure 1  Thresholds

Top Folders and Radio Statistics

To summarize a report, select one or multiple options in the Summarize report by section:

  • Top Folders By Worst Client and Radio Statistics Combined 2.4 GHz, 5 GHz and 6 GHz
  • Radio Statistics by Folder - Combined 2.4 GHz, 5 GHz and 6 GHz
  • Top Folders By Worst Client and Radio Statistics 2.4 GHz
  • Radio Statistics by Folder - 2.4 GHz
  • Top Folders By Worst Client and Radio Statistics 5 GHz
  • Radio Statistics by Folder - 5 GHz
  • Top Folders By Worst Client and Radio Statistics 6 GHz
  • Radio Statistics by Folder - 6 GHz

The statistics displayed can be Client Health, Client SNR, Radio Noise, Radio Utilization, or Radio Interference.

Changing Your Report Summary and Thresholds

To select a new summary method:

  1. Log in to AirWave.
  2. Navigate to Reports > Definitions, and then click Add.
  3. Select Daily RF Health Report.
  4. In the Report Restrictions area, select the Summarize report by options that you want.
  5. Select the statistics to be displayed from the Top Folder Sorting Column drop-down menu.
  6. Define the thresholds for your report.
  7. Click Save and Run or Save.

If an RF Health Report has not been generated before, you can create it by following the instructions on the Creating Custom Reports section of this chapter.

Lists of Top Radio Issues

AirWave tracks the top AP radio issues and lists them by problems. A device will make it into the list of problems if it violates two or more thresholds. For more on the thresholds that indicate problems, refer to Viewing the Radio Statistics Page.)

The lists for most mode changes and most interfering are available if there are ARM events.

Other lists include:

  • Most or Least Utilized by Channel Usage
  • Most MAC/Phy Errors
  • Most Channel Changes
  • Most Transmit Power Changes
  • Clients with Least Goodput
  • Clients with Least Speed
  • Radios with Least Goodput

The RF Health report lists devices that are ranked and then sorted by the third column in the table. Click the blue Device link to access the Devices > Monitor > Radio Statistics page for the radio band.

AirWave limits data storage to 183 days, which is approximately six months, per radio. If you create an RF Health report with range of more than 183 days, the report will only include Channel Changes, Transmit Power Changes, Average Utilization, Mac/Phy Errors and Average Noise based on whatever part of the report intersects the last 183 days. Most reports have data (like bandwidth and users) that maxes out at 425 days. AirWave validates reports so you can only run them over a 366 day duration.

Reports for Clients with Least SNR

Users can export a detailed list of clients exhibiting the lowest Signal-to-Noise Ratio (SNR) values in the RF Health Report to a Comma-Separated Values (CSV) format.

To generate reports for clients with least SNR:

  1. Under RF Health, select any existing Top Folders by Worst Client.

  2. Save and run the report.
    A complete list of clients with least SNR displays.

If running a custom report, select any of the Top Folders by Worst Client along with Clients with Least SNR.
