A graphic shows the associated clients during a given time frame. The client traffic (bps Out and bps In) displays in time
increments of six hours, one day, one week, two weeks, four weeks, three months, six months, one year, or a custom time frame. So basically, this graph would display the aggregate traffic for all the associated wireless clients. Now since this graph is time based,an additional link bar at the top of the graph window displays the options as follows:
6h-the last six hours of data from the current time and current database table
1d-the last day of data from the current time and current database table
1w-the last week of data from the current time and the hourly aggregated table
2w-the last two weeks of data from the current time and hourly aggregated table
4w-the last four weeks of data from the current time and hourly aggregated table
3m-the last three months of data from the current time and daily aggregated table
6m-the last six months of data from the current time and the weekly aggregated table
1y-the last year of data from the current time and weekly aggregated table
Custom-the user can set both the days and hours for the start and end date. The appropriate aggregated source (either current, hourly,or daily) is chosen based on the starting date. After you specify the timeframe, the data for that timeframe is retrieved and the corresponding graph is displayed.
