ios - 在 iOS 中获取 CPU 的 I/O 指标

Question

我一直在 iOS 中寻找如下指标。但是还没有成功。作为这个 Unix 指标环境的新手，我真的很感激能得到任何初学者或帮助。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_wait_state_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);

这是否与 1.system.io.util 中的等待时间相同？
