Some newer kernels have <code>/proc/&lt;pid_of_process&gt;/io</code> file. This is where IO stats are.
It is not documented in man proc, but you can try to figure out the numbers yourself.

Hope it helps.

Don't think there is a way to get the disk and network information on a per process basis.

The best you can have is the global disk and network, and the per process CPU time.

blocks|key|844431|text|解决此类问题的最好方法是查找执行类似监视和报告的工具的源代码。虽然不能保证他们直接使用/proc，但他们将引导您找到解决问题的有效方法。对于您的情况，您会想到top(1)、iotop(8)和nethog(8)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|844432|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

The best way to approach problems like this is to look up the source code of tools that perform similar monitoring and reporting. 
Although there is no guarantee that they are using /proc directly, they will lead you to an efficient way to tackle the problem.
For your case, top(1), iotop(8) and nethogs(8) come to mind.

I want to use the /proc to find the resource usage of a particular process every second. The resources include cputime, disk usage and network usage. I looked at /proc/pid/stat , but I am not sure whether I am getting the required details. I want all 3 resource usage and I want to monitor them every second.

Getting Linux process resource usage (cpu,disk,network)

Linux

我想使用/proc每秒查找特定进程的资源使用情况。资源包括cputime、磁盘使用率和网络使用率。我查看了/proc/pid/stat，但我不确定是否获得了所需的详细信息。我想要所有3个资源的使用情况，并且我想每秒监控它们。
