Hostgroup-Capacity-Planning-Linear-Regression

Description

This report shows the evolution and performance forecasting metrics for a host group.

How to interpet the report

The evolution of the metrics value is represented on a graph and in a table. Forecasts are calculated from the reporting period metrics value and projected into the future. An additional table provides information about critical threshold and days before saturation.
