Storage System Components and Recommended High Resolution Sampling Interval
Table 4 (page 27) gives an overview of the storage system components, example values (per
system), and the recommended high resolution sampling intervals that add to the database space.

Sampling Parameters
Table 5 (page 27) describes the collection settings that affect the size and performance of the
System Reporter.

ratio collection will be performed. For example, with Hi Res interval =
5 and Ratio = 6, a Hi-Res space sample will be taken every 30
minutes.
