6.3.7.5 Troubleshooting
Problems can occur with Time View running on Windows Vista. To disable Time View from the
GUI, click the second link on the cluster webstart page which launches HP Insight CMU without
Time View. In the CLI, set –Detrunk=false argument.
If Time View prints an "OutOfMemory [...]" error, try increasing the maximum HEAP memory usage
of the GUI. To specify the memory consumption allowed for the JVM, set the –Xmx JVM argument
when starting the CLI. In the GUI, edit CMU_GUI_MB (specified in MB) in cmuserver.conf.
IMPORTANT:
Setting this value too high may create "Unable to start JVM" messages on hosts with insufficient
memory or on hosts running a 32-bit JVM. HP recommends a 64-bit JVM, and requires it for large
clusters.
If Time View stops running, a restart button appears below the Time View panel.
Some GPUs may not support anti-aliasing levels set to 8. Symptoms are black strips on the left and
right of Time View, or cylinders above the rings making the visualization inoperable. If this occurs,
set anti-aliasing to a lower value such as 4.
6.3.8 Archiving user groups
Monitoring data for deleted user groups can be archived and visualized later as “history data”.
To archive monitoring data for deleted user groups:
1. Delete a user group
2. Answer Yes to Do you want to archive this User Group?
See Figure 39 (page 95).
Figure 39 Archiving deleted user groups
After the delete operation is complete, then the user group displays in the list of Archived User
Groups in the left-frame tree. See Figure 40 (page 96)
