You can choose the period using either a Start time and End time or a Start time and Period. The period is configured as a quantity (1 to 100) of time units (minutes, hours, days, weeks, months or years).
The maximum number of data samples per variable is 12000. If the period that you enter causes this to be exceeded, the most recent are used.
