Disk space use history for a VOB or view
The Host VOB Storage node displays information about disk space used by a VOB, and the Host View Storage node displays information about disk space used by a view.
The VOB Space History or View Space History tab displays space use history as a graph. If the VOB or view storage spans multiple disk partitions, there is a separate graph for each partition. To view a graph for a different partition, click the partition in the Select partition to view box.
The colored bands of each chart represent subdirectories of the VOB or view storage directory.
The VOB Space and View Space tabs display current data on space used by the VOB or view.
This display uses previously generated data that has been cached on the VOB or view server host. This data is usually generated by the Daily VOB Space or Daily View Space scheduled job. If no data is available, you can use the ClearCase scheduler to run the job on the VOB or view server host.
VOB space display
For each partition, the VOB Space graph displays historical trends in space used by the following parts of the VOB storage directory:
- VOB database, containing such information as types, instances of types, configuration records, and event records.
- Source storage pools, containing the data for versions of file elements.
- Derived object storage pools, containing derived objects referenced by more than one view. The Derived Objects node displays disk space used by shared DOs.
- Cleartext storage pools, containing cached versions of file elements.
- Miscellaneous VOB storage space, including VOB administration data.
The chart also shows space in the partition that is in use but not used by this VOB and remaining free space in the partition.
View space display
For each partition, the View Space graph displays historical trends in space used by the following parts of the view storage directory:
- View database, containing such information as records of checked-out versions and, for dynamic views, configuration records of unshared derived objects.
- View-private storage (dynamic views only), containing view-private files, checked-out files, and unshared derived objects.
- Miscellaneous view storage space, including view administration data.
The chart also shows space in the partition that is in use but not used by this view and remaining free space in the partition.
Display options
Click Options to open a dialog box that allows you to change display options for the VOB or view space displays.
- On the General tab, you can change the colors used in the charts.
- On the Space History tab, you can select which parts of the VOB or view storage directory to display in the space history chart. You can also select Automatic scaling to force the Y-axis of the display to a scale proportional to the space used by the largest selected component. If you do not select Automatic scaling, the Y-axis of the display is based on the total capacity of the selected partition
