Long Term Trend
The FortiWLM MEA collects the statistical data from the controller and provides an option to view the Long Term Trend for predefined parameters. The long term trend data is a graphical representation for the statistics gathered over the period of time.
The Long Term Trend dashboard displays the per controller view or the aggregate-controller view (default view). The trend data for a maximum of one year and a minimum period of two hours is displayed. The long term trend data stored in the database cannot be modified. The FortiWLM MEA summarizes the data in three pre-defined sample periods.
- Hourly - If the time range to be graphed is 1 month or less than one month, the trend graph is displayed with hourly sample points. This is the default view.
- 8 Hours - If the time range to be graphed is more than one month and less than 8 months, the trend graph is displayed with 8 hours sample points. The sampling time can also be configured on the Maintenance screen (Administration > Maintenance > Statistics section > Long Term: 8 Hourly Data Aggregation Period Begins At (AM)).
- 24 Hours - If the time range to be graphed is more than 8 months and up to 1 year, the trend graph is displayed with 24 hours sample points.
By default, all controllers are included but you can select a specific controller from the controllers list. In this case, data is automatically refreshed. Enter the period manually or select the calendar icon to set the date and time.
