请大家多提意见，共同富裕哈
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 = 0;
counts = COUNTER;
secs = INTERVAL;
}
sysinfo:unix:idle_enter:idlethread
{
idle = 1;
}
sched:::on-cpu
/idle/
{
this->elapsed = ((timestamp - cpustart)/20000000)*2;
@Procs["IDLE"] = sum(this->elapsed);
}
sched:::on-cpu,
sched:::remain-cpu
{
idle = 0;
cpustart = 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);
}
