Some columns are expressed in terms of totals, deltas, or
cycles:
Total means data that is displayed as an absolute value
or string. For some parameters it is defined as the total number of
occurrences since the server last started; for others it is a
quantity expressed by the service (for example, staging space in
use).
Delta means show delta during this refresh period: the
difference between the absolute between the last two refresh
intervals.
Cycle means the total number of occurrences within a 24
hours period. If a 24-hour period has not elapsed (i.e., the server
started less than 24 hours ago) the value is null.
