计算方式

通过Python的模块os来实现

import psutil
import os

# parts = [sdiskpart(device='rootfs', mountpoint='/', fstype='rootfs', opts='rw')]
parts = psutil.disk_partitions(all=True)
for part in parts:
    # posix.statvfs_result(f_bsize=4096, f_frsize=4096, f_blocks=2618624, f_bfree=2441314, f_bavail=2441314, f_files=5242368, f_ffree=5216866, f_favail=5216866, f_flag=4096, f_namemax=255)
    inodes = os.statvfs(part.mountpoint)
    total = inodes.f_files
    free = inodes.f_ffree

    system.fs.inodes.total = total
    system.fs.inodes.free = free
    system.fs.inodes.used = total - free
    system.fs.inodes.in_use = (total - free) / total
