If you're wondering about kernel mode usage, try this:

$ ANA/SYS
SDA> READ/EXEC ! get better symbolization (routine names)
SDA> LOAD PCS ! PC sampling SDA Execlet
SDA> START TRACE
...
SDA> STOP TRACE
SDA> SHOW TRACE/STAT/MODE=KERNEL
...
SDA> UNLOAD PCS
SDA> EXIT

SHOW TRACE/STAT/MODE=KERNEL will show the PC values seen most often during the trace period (sorted by decreasing no. of occurences) and it will symbolize the PC values as routine names or execlet names. This might give you an idea, which kind of kernel mode code is running how often.
