# Total, Average, Minimum, and Maximum Values

The total, average, minimum, and maximum values are calculated for rollups and for reporting purposes. These values let you observe the upper and lower bounds of performance across a given time interval.

A
rollup
is the process during which metric values are aggregated. In an hourly rollup, the 1 minute, 5 minute, 15 minute, 30 minute, and 60 minute polled values for metrics are aggregated every hour. In a daily rollup, as-polled values for metrics are aggregated once a day. In a weekly rollup, daily values for metrics are aggregated once a week. A given metric is aggregated by either averaging or summing data points during the rollup (not both) based on the "RollupStrategy" configured for that metric.
Hourly rollups:
• Total: Sum of all the as-polled data points for the hour.
• Average: Sum of all the as-polled data points divided by the number of data points for the hour.
• Minimum: The lowest single poll value of the hour.
• Maximum: The highest single poll value of the hour.
Daily rollups:
• Total: Sum of all the as-polled data points for the day.
• Average: Sum of all the as-polled data points for the day divided by the number of data points.
• Minimum: The lowest single value of the hourly minimums.
• Maximum: The highest single value of the hourly maximums.
Weekly rollups and beyond:
• Total: Sum of all the daily data points for the week.
• Average: Sum of all the daily data points divided by the number of data points for the week.
• Minimum: The lowest single value of the daily minimums for the week.
• Maximum: The highest single value of the daily maximums for the week.
Five-minute resolution reporting:
• Total: Sum of all the as-polled data points for the 5 minute increment.
• Average: Sum of all the as-polled data points divided by the number of data points for the 5-minute increment.
• Minimum: The lowest single poll value of the five-minute increment.
• Maximum: The highest single poll value of the five-minute increment.
One hour resolution reporting:
• Total: Sum of all the as-polled data points or the hourly rollup value for the hour.
• Average: Sum of all the as-polled data points divided by the number of data points or the hourly rollup value for the hour.
• Minimum: The lowest single value of the as-polled data or hourly rollup minimum for the hour.
• Maximum: The highest single value of the as-polled data or hourly rollup maximum for the hour.
Day resolution reporting:
• Total: Sum of all the hourly data points or the daily rollup value for the day.
• Average: Sum of all the hourly data points divided by the number of data points or the daily rollup value for the day.
• Minimum: The lowest single value of the hourly data or daily rollup minimum for the day.
• Maximum: The highest single value of the hourly data or daily rollup maximum for the day.
