获取iOS中CPU的I/O指标

Question

我一直在寻找如下iOS中的指标，但没有成功。在这个Unix指标环境中，我非常感激得到任何初学者或帮助。 谢谢。

1.system.io.util - The percent of time the CPU spent waiting for IO operations to complete.

2.system.cpu.iowait - The percent of CPU time during which I/O requests were issued to the device

在task_wait_state_info细节有一个可用的结构如下：

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); 

这是相同的等待时间作为1.system.io.util？

在github上有一个叫做GodEye的软件项目，它有工作迅速的代码来回答你的问题。看看：https://github.com/zixun/GodEye

• monitor for the log and point out log type. 
• monitor for the crash, include Uncatched Exception and Signal. 
• monitor for the network, all information of request and response. 
• monitor for the ANR, tell you the stacktrace of all threads. 
• monitor for the memory leak, tell you the leak object's class name. 
• a terminal for you to customized your commands and things what to do. 
• monitor for the cpu usage of system and application. 
• monitor for the ram usage of system and application. 
• monitor for the FPS. 
• monitor for the netflow of system and application. 
• a file browser for look through the sandbox, .app and root directory. 
• custom and runtime setting
