|Tools and Modules / Visual Statistics Display|
Start the VSD tool, load statistics files, and maintain the view you want on your statistics.
VSD is a free analysis tool and is provided as-is.
Starting in Pivotal GemFire 7.0, VSD is distributed with Pivotal GemFire. To install VSD, install Pivotal GemFire. See Installing Pivotal GemFire for instructions.
After you install GemFire, you can find VSD in the following location of your GemFire installation:
Where <product_directory> corresponds to the location where you installed GemFire. If you installed using RPM, the default location is /opt/pivotal/Pivotal_GemFire_XX where XX corresponds to the version of GemFire (for example, Pivotal_GemFire_70) that you have installed
vsd <filename.gfs> ...
After you load the data file, the VSD main window displays a list of entities for which statistics are available. VSD uses color to distinguish between entities that are still running (shown in green) and those that have stopped (shown in black).
If you select the menu item File > Auto Update, VSD automatically updates your display, and any associated charts, whenever the data file changes. Alternatively, you can choose File > Update periodically to update the display manually.
Some statistics are cumulative from when the GemFire system was started. Other statistics are instantaneous values that may change in any way between sample collection.
Cumulative statistics are best charted per second or per sample, so that the VSD chart is readable. Absolute values are best charted as No Filter.
