Answer

  • The statistics in the performance view represent averages over each interval, rather than point-in-time values.
  • The data is collected and averaged over defined sampling periods.
  • The values reflect the average performance metrics for the respective interval leading up to the timestamp.
  •  The sampling period or averaging method used for each interval is:
    • For the 1-hour and 1-day intervals, the data points represent averages over 5-minute periods.
    • For the 1-week interval, the data points represent averages over 30-minute periods.
    • For the 1-month interval, the data points represent averages over 2-hour periods.
    • For the 1-year interval, the single data point per day represents the system's state at 01:00 am.
  • There might be some smoothing or aggregation techniques applied to ensure a consistent representation of the performance metrics.
