Visual Statistics Display (vsd) is a graphical tool that allows you to view statistics generated by the GemStone/S 64 Bit or GemStone/S server, or by GBS.


VSD allows you to monitor performance, in a live system or offline, and can help diagnose many kinds of problems that may occur in complex systems.


VSD is distributed with GemStone/S and GemStone/S 64 Bit on UNIX, Linux, and Mac platforms, and with Windows in v.3.2 and later. GemStone server Windows client distributions on earlier versions do not include VSD.
