When viewed for today only, the sidebar for each section on the Details page gives an indication if it is currently impacting the associated heat tile colour. This applies for collapsed sections also.

Today only

Colour coding applies to Channel Load, Client Count and Access Point sections.

2.4 GHz and 5 GHz channel load charts show the utilisation of the WiFi channel (the percentage of time the channel is busy – either from other devices transmitting or interference). A vertical bar is drawn on the chart for each poll (typically every five minutes). As utilisation approaches the threshold, the vertical bar shows green through amber then red and maroon when the threshold is exceeded.

Threshold

The custom defined threshold is indicated with a thin horizontal purple line and shown in purple text in the right margin. The threshold value is 50% by default but can be altered by Admin users. See WiFi Alerting Thresholds for more information.
If configured, an alert can be sent when channel load exceeds the threshold.

Vertical axis

Scaling adjusts depending on data

   50%

If the adjusted vertical axis means the threshold line is not visible then a purple arrow is shown indicating the threshold is above the visible chart area.

Horizontal axis

Adjusts according to the selected time period to show "hours" in day view and "days" in week and month views; redraws if the time zone is changed at the top right of the Details page

Zoom options

Drag: click, hold and drag across the chart to zoom into a time period; repeat if needed and   Reset zoom   if complete
Note: all charts are synchronised so they zoom in and out together
Click: on a week or month view, click on the chart to jump to that specific day view

Highlight displays the values for each data point in the time period:

Day

Shows multiple data points per hour (one for each polling period, usually one to five minutes)

Week

Shows 24 data points per day (every hour), Maximum for each hour is shown

Month

Shows 6 data points per day (every 4 hours), Maximum for each 4 hour period is shown

For any time period, hover on a point to see date, timestamp, channel load and congestion as a percentage.

Congestion represents the number of retransmitted or failed frames expressed as a percentage of frames to be sent. The calculation is manufacturer dependent and based on the statistics available from the WiFi devices. Congestion is not calculated unless traffic volumes are more than one frame per second. Colours on the congestion line are:

Green

Values are at or below the threshold

Red blips

Values exceed the threshold

Grey

No samples or congestion of 0%

Threshold

The threshold for congestion is set to 12% by default and can be altered by Admin users. This indicates how congested the AP radio networks are and uses the percent of send attempts that require retransmissions as the metric. The custom threshold is shown in purple text in the right margin. See WiFi Alerting Thresholds for more information.
If configured, an alert can be sent when congestion exceeds the threshold.

Grey/White backgrounds - Business hours

By default, the chart shows non-business hours with a vertical grey background and business hours with a vertical white background on day and week views. Business hours are not shown on a month view. Toggle off to show alternate horizontal grey and white background areas.

Business hours are the time periods (to the nearest hour) that a business is operational. Highlight uses business hours when displaying charts on the Details page, filtering reporting results and generating alerts. Default values are 06:00 to 18:00 Monday through Friday with Saturday and Sunday excluded. However, you may see different settings if the business hours on a parent folder or location have been changed. Business hours reflect the local time zone for the location.

Purple backgrounds - Maintenance

Any purple background areas on the chart show current and past maintenance periods. Watches in maintenance do not send alerts, change the colour of heat tiles or decrement the availability figure for the time period.

Find out more about maintenance indicators on the details page.
