Time series forecasting visualizes the expected trends of a metric in a specified time period and generates alerts about potential breaches. For example, a forecast alert can be notified when a disk is expected to run out of space in five days.

Forecasts have the following behaviors:

• The forecast model provides forecasts once per day.
• If a forecast model learns that a forecast is not going to breach a limit, an existing forecast alert is removed.
• To commence a forecast, at least 20 days of disk metric data must be collected. This means that a new resource wo not have a forecast until 20 days have passed.

Forecast monitoring can be applied to a maximum of 25 resources. To request more resources, contact support.

Forecast applicable metrics

Metrics that support metrics can be used for agent or gateway collector types:

• For agent collector types, forecast monitoring is configured only on Application Monitors.
• For gateway collector types, forecast monitoring is configured on Application Monitors and Monitors.
