To run the Port Discard Trend report
The Port Discard Trend report provides regression-based trend prediction for port discards. This report enables you to see port discard predictions for the next 6 months, for both inbound discards and outbound discards. Predictions are made by applying regression analysis to the selected device's historical port discard data, which by default is for the previous 8 weeks, but you can configure this figure.
