Monitoring virtual disk performance
Virtual Disk Manager,
select a virtual disk, select Examine
Performance from the Disk menu, then click
on Refresh to obtain current statistics.
A snapshot of disk I/O statistics and read/write ratios are displayed for the virtual disk and for individual disk pieces within it. ``Application and filesystem requirements'' explains the statistics displayed.
Use the Refresh button to update the statistics or the Zero button to clear existing statistics.
Use this information to monitor I/O activity on your system. To reduce performance constraints, balance the I/O more evenly as described in ``Application and filesystem requirements''. For more information on tuning your system, see ``Tuning virtual disk performance'' in the Performance Guide.
