signal-send

您可以使用 signal-send 探测器确定与任何信号关联的发送和接收进程，如下例所示：

#pragma D option quiet

proc:::signal-send
{
	@[execname, stringof(args[1]->pr_fname), args[2]] = count();
}

END
{
	printf("%20s %20s %12s %s\n",
	    "SENDER", "RECIPIENT", "SIG", "COUNT");
	printa("%20s %20s %12d %@d\n", @);
}

运行此脚本将会生成与以下示例类似的输出：


# dtrace -s ./sig.d
^C
              SENDER            RECIPIENT          SIG COUNT
               xterm               dtrace            2 1
               xterm          soffice.bin            2 1
                  tr                 init           18 1
               sched                 test           18 1
               sched                fvwm2           18 1
                bash                 bash           20 1
                 sed                 init           18 2
               sched                  ksh           18 15
               sched                 Xsun           22 471
