ure, and click Configure Log Purge.
The Configure Log Purge page opens:
There are four options from which you can choose
the configuration of purging:
• Use default values below which are the global de-
fault values - purging of logs depends on the value
that is pre-configured in the system.
• Keep logs forever (do not delete) - logs will never
be deleted (depending on what specific level of the
tree the activity was clicked on). For example, in the
figure above, log data of directory “Steve Desk” will
be stored in the database permanently.
• Delete logs with date values older than specified
number of weeks - purges logs that are older than
the number of weeks that is specified by the user.
Click the radio button to enable the Number of
weeks keep drop-down and select a number from
the list (choices are from 1-156). For example, if 2 is
selected, the system will only store logs that are 2
weeks old or less and purge logs that are older than
2 weeks.
• Compact log data based on the following rules -
logs older than the date that you specify will be re-

AVERAGE: Log values for the established time period
will be added and the sum of all values will be divided by
the number of logs.
MAXIMUM: Over the set period of time, the log with
the highest (max) value will be stored.
MINIMUM: Over the set period of time, the log with
the lowest (min) value will be stored.
Example: Logs recorded were 10, 20, 10, and 10. Com-
paction by AVERAGE will yield a log value of 12.5. Com-
paction by MAXIMUM will yield a log value of 20 and a
value of 10 if by MINIMUM.
• Over a/Period
: Logs will be compacted depending
on these settings. Specify the amount of time for
compression of the AVG, MIN, or MAX values. Se-
lect a unit of time from the Period drop-down and
choose a number from the Over a drop-down.
