cswstat.d - context switch time stats. Uses DTrace. cswstat.d cswstat.d is a DTrace program to print context switch time statistics. This program measures the time consumed during context switching, and prints it with the number of context switches and the average time. Since this uses DTrace, only the root user or users with the dtrace_kernel privilege can run this command. Solaris stable - needs the sched provider.
