Visual Statistics Display (VSD) version 5.6.5 is a new release of the VSD product, improving support for viewing very large statmonitor data sets.
These release notes describe changes between the previous version of VSD, version 5.6.4, and version 5.6.5.
This version of VSD supports statmonitor files generated from:

Changes in this Release
Limit display by the number of samples
Some applications may have many short-lived sessions. When analyzing statmonitor data containing a very large number of sessions, these short-lived sessions make it cumbersome to locate processes and identify sessions creating bottlenecks.
Now, you can hide processes (sessions, process threads or other entities) with only a small number of samples, from the list in the Main window process list. The Main Window menu bar Main, and the popup menu, include the menu item Hide Instances By Samples..., which has submenu items Clear All Hidden By Samples and Select Sample Threshold....
Select Sample Threshold... opens a dialog allowing you to enter a number up to 5000. Samples with this many or fewer samples are hidden in the list of sessions in the main window.
Clear All Hidden By Samples clears any previous setting using Select Sample Threshold....
Line-trimmed process no longer displayed in main window
The Chart menu options Trim Left and Trim Right allow you to restrict VSD’s display to only the period within the untrimmed range. Previously, sessions who were not alive at any point within the trimmed period remained visible in the Main window process list, with a sample count of 0. Now, these processes are not displayed.
Show PIDs in Chart Legend
The legend in a Chart Window identifies Gems by name and sessionId. While sessionIds are unique at a given time, they are reused once that session logs out, and thus on a larger system or a system with many short-lived sessions that do not set unique cache names in the application, there may be many sessions with identical name-sessionId identifiers in the legend. Now, the PID of the session can be included in the legend, so the legend identifier is name-sessionId(PID).
This applies to all GemStone processes, will make the Legend use more space, so this option can be enabled/disabled. It is configured using the Main Window and Chart Window added option Chart > Show PID in Legend. The state is saved to .vsdrc and will be the default on vsd restart.
