The Hardware Statistics tab (or Statistics, for Teradata Machine Learning Engine) displays information over a specified time interval. You can view statistics for the last hour, 12 hours, or 24 hours and export the statistics. The metrics in the list beneath the graph are the current values. The plot lines on the graph represent values collected over the selected time frame. Select a metric name to see the plot line highlighted and surrounded by the performance envelope in the graph.
