as well as the file descriptors that belong to the process.
I/O information is read from /proc/pid/io.
Cgroup information is read from /proc/pid/cgroup.
Scheduler information is read from /proc/pid/sched.
Process status information is read from /proc/pid/status.
File descriptors information is read from /proc/pid/fd.
