获取iOS中CPU的I/O指标

我一直在iOS中寻找下面这样的指标。但是还没有成功。作为这个Unix指标环境的新手，我非常希望在这方面获得任何初学者或帮助。 谢谢

1.system.io.util—CPU等待io操作完成的时间百分比。

2.system.cpu.iowait-向设备发出I/O请求的cpu时间百分比

在

task\u wait\u state\u info

的详细信息中，有一个结构可用，如下所示：

struct task_wait_state_info {
uint64_t  total_wait_state_time;    /* Time that all threads past and present have been in a wait state */
uint64_t  total_wait_sfi_state_time;    /* Time that threads have been in SFI wait (should be a subset of total wait state time */
uint32_t  _reserved[4];
};


task_wait_state_info_data_t waittime;
NSLog(@"Wait time : %llu",waittime.total_wait_state_time);

这与

1.system.io.util

中的等待时间相同吗？
