History Collection and Archiving
PlantScape Server and Client Configuration Guide 173
To configure history archives:
1 From the System Configuration Menu display, click History Archiving.
2 Using the checkboxes under History Types to Archive, select the history
types you want to archive. (See “Types of History Collection” on page 167
for a detailed description of history types.)
3 Enter the minimum free disk space that must be available for this archiving
job to run. This prevents all of the free disk space on the server from being
used for history archive files. (If the disk becomes full, system performance
will be severely degraded.)
Deciding When to Archive History
Note Applicable to the History Archive report only.
The number of samples and the interval specified for history collection determine
how often archiving needs to be performed if all history samples are to be saved
for a particular history interval. To find out the default retention periods for
history intervals see Table 8.3, “Default Retention Periods,” on page 168.
For example, if the database can store 24 hours of one-minute history, the
one-minute history interval will need to be archived once per day.
To configure a history archive report:
1 From the System Configuration Menu display, click Reports. The Reports
display is called up.
2 On the Reports display, click any blank line. The Report Definition tab is
called up.
3 From the Report type drop-down list, select History Archive.
4 Specify other details as required. You must select at least one of Enable
reporting on request or Enable periodic reporting checkboxes if you want
the archive configuration to be run.
5 Click the Content tab.
6 Using the checkboxes under History Types to Archive, select one or more
history types and intervals. (See “Types of History Collection” on page 167
for a detailed description of history types.)
7 Under Archive Location, you can specify any folder as the root of a path to
this archive. To use the default History Archive folder, leave this field blank.
Note It is possible to specify an Archive Location folder that is not
included in the History Archive path. If you want PlantScape to access this
archive, you must add the folder to the History Archive path (for details, see
“Configuring History Archiving” on page 170).
