Threshold settings allow you to place time parameters for data aggregation. Charts of results and monitor data aggregate at different levels depending on the overall length of time displayed on the X-axis. By default, charts aggregate at the second level. If a chart displays more than 10 minutes of data, then it aggregates data at the minute level. If a chart displays more than 1440 minutes of data (24 hours), then it aggregates data at the hour level. The steps below show how to change those thresholds.
