Viewing the Home > Network Deviations Page

The Home > Network Deviations page provides graphs that track your network's Client and Usage information and

draw attention to unusual network usage patterns. These graphs can show you, for example, if heavy network traffic is

occurring during off hours, or they can be used to detect the time(s) of day when your network traffic peaks.

By default, the graph lines display, in five-minute intervals, the previous 2 hours of client and usage information for the

current day of the week averaged out over the last 40 weeks. The shaded area indicates the standard deviation, which

defaults to 1. So, for example, if you launch this page at 9:00 am on a Friday, then a 2-hour graph will show the current

and average number of connected clients and usage between 7:00 AM and 9:00 AM on all Fridays over the last 40

weeks, with plot points showing the number of clients for every five minutes. You can also select/drag a set of plot

points to zoom in and view a more precise time range. Click the Reset zoom button to return to the specified time range.

You can change the time range of the graphs to 4 hours, 8 hours, or 1 day using the time-range options in the upper-

right corner of this page, and AirWave will remember the new setting the next time the page is launched.

The left graph shows client information - specifically the current and average number of clients over the last 40 weeks

during the selected time range. The right graphs show usage information - specifically the current and average incoming

and outgoing bits-per-second over the last 40 weeks during the selected time range. The shaded/gray color within the

graphs indicates the standard deviation. Any blue lines (Avg Clients, Avg Out Usage) or green lines (Avg In Usage) that

appear outside of the shaded/gray area can be considered deviation points because the value does not come within the

range of the calculated standard deviation.

This operation can consume a significant amount of CPUcapacity as it parses through large amounts of data. Larger

deployments you may have to wait up to a minute before seeing the initial graph plot points. In addition, this page does

not automatically refresh, rather it refreshes each time this page is selected and/or each time you click Refresh. As a

result, if you click this page, navigate away, and then return to this page, the page will begin to load again. If your network

includes a large amount of data, then a best practice is to open this page in a new tab before navigating to another page.

In this case, the Network Deviations page will continue to load while you continue to work in AirWave.
