Statistics used in out-of-the-box capacity views

When time series data is loaded by an ETL from a data source, it may have unaligned time stamps and duration. BMC Helix Continuous Optimization transforms this data into a form usable for analysis and reporting. All imported samples are available at their original resolution in the raw metric store for three months. The metric store computes hourly aggregate resolution and retains it for a longer period with multiple statistics, such as AVG and Max.
