从Linux内核虚拟文件系统检索信息

Question

I am wanting to write a utility that does some reporting based on data available in the /proc directory.

Is this as simple as reading and parsing the contents of the virtual file I am interested in? I have seen this approach implemented in Python when doing similar things.

Is there a superior way to do this in Go?

For backstory, I am using ZFS on Linux and want to retrieve data from this virtual file: /proc/spl/kstat/zfs/arcstats

This is a Python program that operates directly on that file.

As far as I know: yes.

But you might try looking at github.com/c9s/goprocinfo to see what they do there, or if you can use that package instead.
