This report lists and graphs, in chronological order, the total and average disk usage by week for study CRF images.
DF_WFdiskusage lists and graphs disk usage by week. For each week, the week number, the number of Kbytes of disk used, and a histogram representation of the Kbytes used, is displayed. Weeks in which there was no disk usage are never displayed, but they can influence the calculation of the average as described below.
Summary statistics, including the total number of Kbytes, the average number
of Kbytes per week, and the minimum and maximum Kbytes, are presented after
the histogram. The minimum and maximum usage weeks are also indicated on
the histogram by the abbreviations min and
max respectively.
In the case where more than one week has the minimum or maximum usage,
only the first such week is indicated.
Weeks in which there was no disk space used are excluded
from the minimum calculation.
Zero usage weeks are also excluded from the
calculation of the average Kbytes used per week, unless -a is
given. If -a is given, the total number of weeks considered
in the average calculation is the number of weeks between the first and last
week inclusive.
Otherwise, only those weeks with non-zero usage are counted, which is the
default.
Study weeks are specified with a yyww notation where
yy is the 2-digit year of the century and ww
is the 2-digit week of the year.
By default, the range of weeks begins with the first week that a fax
image was received and ends with the last week that an image was received.
If -a is given, the last week is taken as the current week.
These defaults can be overridden by specifying either or both of
-f and -l.
By default, weeks are listed in chronological order, least recent first. If
-r is specified, weeks are listed in reverse chronological
order, most recent first.
Scaling of the graph can be overridden with -g.
The value specifies the number of Kbytes represented by each
* character.
By default, the scaling factor is calculated to achieve full use
of an 80-column page.
-a | Include all weeks in the calculation of the mean, including those weeks for which no CRFs were received |
-r | Display weeks in reverse chronological order (most recent week first) |
-g | Set graphics scaling to one * per #
Kbytes |
-f week | Include only weeks on or after the specified week |
-l week | Include only weeks before or on the specified week |
