solaris 10中编写了一个DTrace脚本，实现输出：IDLE在CPU中的时间占用率。源程序如下：
#！/usr/sbin/dtrace –s
dtrace:::BEGIN
{
COUNTER=3;
INTERVAL=1;
        cpustart[cpu] = 0;
        counts = COUNTER;
        secs = INTERVAL;
}
sysinfo:unix:idle_enter:idlethread
{
        idle[cpu] = 1;
}
sched::n-cpu
/idle[cpu]/
{
        this->elapsed = ((timestamp - cpustart[cpu])/20000000)*2;
        @Procs["IDLE"] = sum(this->elapsed);
}
sched::n-cpu,
sched:::remain-cpu
{
        idle[cpu] = 0;
        cpustart[cpu] = timestamp;
}
profile:::tick-1sec
{
        secs--;
}
profile:::tick-1sec
/secs == 0/
{
        printf("%16s %16s\n", "THREADS", "TIME (%)";
}
profile:::tick-1sec
/secs == 0/
{
        printa("%16s %@16d\n", @Procs);
        trunc(@Procs);
        secs = INTERVAL;
        counts--;
}
profile:::tick-1sec
/counts == 0/
{
        exit(0);
}
dtrace:::END
{
        trunc(@Procs);
}
