Sample Resolution
The Sample resolution control enables you to select from one of three resolutions corresponding
to the tables that are maintained in the database (see
Table 6 (page 67) ). The samples can be
retained for different lengths of time for each resolution (see “Editing Sampling Policies” (page 115)
for instructions on altering the default sampling policies).
Since a different set of objects may be present in data tables for different resolutions, the generated
report menu is populated with the objects present in the tables for the selected resolution.
Table 6 Sample Resolution
Purpose Option
Choose the Daily data table, which covers the largest time range, but has the coarsest
resolution with only one sample per day. Daily
Choose the Hourly data table, which covers a shorter time range than the daily data table,
but has one sample per hour. Hourly
Choose the High-Resolution data table, which spans an even smaller time range, but has
the finest granularity. High-Res
