Generating ForecastsΒΆ

To generate a forecast, a report must first be run to define the scope of data for extrapolation.

The following data elements in a report will be used to generate the forecast:

  • Hosts

  • Data points

  • Time period covered

  • Filters applied

In the results/output, click the Forecast button, and then enter a name to save the new forecast under. The main Investigate > Forecasts page will automatically be displayed after the forecast is created.

Note

The amount of time it takes to generate a forecast varies, depending on the amount of data that needs to be processed.

Forecast horizon and seasonality customization

By default, Plixer Scrutinizer applies a recommended forecast horizon and seasonality based on the volume of data sampled in the report used.

To manually define the horizon and seasonality instead, the filename for the forecast should be formatted as follows:

[forecast_name] ? [horizon_integer] [time_unit] with <no | auto | null> <season> [season_integer] [time_unit]

Natural language is also supported, so a forecast titled:

VPN Usage ? for 3 months with a season of 14 days

will generate a forecast with projected values for 3 months (after the end of the report time range/window) and a seasonality of 14 days.
