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 Health sections. The Channel Trend chart displays historic trend data and thus does not impact any heat tile colours. The indicator will always be green for today on Channel Trend.

2.4 GHz (left) and 5 GHz (right) 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). Each graph includes peak and mean values.

By hour

In a new window, show utilisation levels in two hour time periods. This option is available on a day views only, not on week and month views.

For the selected day, this dialog shows more detailed view of both 2.4 GHz and 5 GHz channels. Each vertical line on the chart shows the actual utilisation for an individual poll.

View selected date/time

Set to  24h  for the full day or centre the chart on an hour. For example, selecting  08  will set the chart from 07:00 to 09:00.

This toggle will automatically move to Today and display a period covering the current hour and previous hour. This auto refreshes every 3 minutes. Switching the toggle off will return you to the initially selected date.

Aerohive, Aruba AirWave and Meraki: Channel load information is not returned by the vendor so these charts are disabled, see image below

This section shows graphically the number of clients for the selected time period (day, week, month) and date. It also shows the percent of clients with signal problems.

Client Count

A vertical bar is drawn on the chart for each poll (typically every five minutes). The custom defined threshold is indicated with a thin horizontal purple line and shown in purple text in the right margin. When client numbers are at or below the threshold, the vertical bar is green. When client numbers exceed the threshold, the top of the vertical bar turns to red. The threshold value is 30 client devices by default but can be altered by Admin users. See WiFi Alerting Thresholds for more information.

Signal Problems

The threshold for Signal Problems is configurable and set to 25% by default. This is 25% of clients on a WAP with poor signal strength. A poor signal strength is defined as one or two bars or below 20 decibels. The custom threshold is shown in purple text in the right margin.
The line is green when the percent of clients with signal problems is at or below the threshold. Red blips are shown when the percent of clients with signal problems exceeds the threshold. The line is grey if client count is 0 or there are no samples.

A purple background on the chart indicates a maintenance window. APs in maintenance do not send alerts, change the colour of heat tiles nor decrement availability figures

Similar to Highlight's Line Health Chart, this shows:

• CPU Util:

  as a colour gradient with red indicating 70% load

• Signal:

  shows coloured blips based on the user-defined threshold. The blips change colour as the percent of clients with signal problems approaches 100%. A poor signal strength is defined as one or two bars or below 20 decibels. By default the threshold is 25% of all connected client devices but this can be custom defined. See WiFi Alerting Thresholds for more information.

• 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 graphics are:

Congestion	Up to and including 2%	Up to and including 7%	Up to and including 12%	Up to and including 17%	Up to and including 22%	Greater than 22%
Colour	Ignored	Blue	Green	Yellow	Orange	Red

• Availability:

  shows coloured blips to indicate the following:

Blip Colour	Issue
Blue	No data, controller is not contactable
Red	AP reported as Down
Deep Red	If the access point has been shut down deliberately on the wireless controller console: AP taken out of service
Turquoise	Either of the radio frequencies changed channel between polls
