nfsiostat

Emulate iostat for NFS mount points using /proc/self/mountstats

root@kali:~# nfsiostat -h
Usage: nfsiostat [ <interval> [ <count> ] ] [ <options> ] [ <mount point> ]

 Sample iostat-like program to display NFS client per-mount' statistics.  The
<interval> parameter specifies the amount of time in seconds between each
report.  The first report contains statistics for the time since each file
system was mounted.  Each subsequent report contains statistics collected
during the interval since the previous report.  If the <count> parameter is
specified, the value of <count> determines the number of reports generated at
<interval> seconds apart.  If the interval parameter is specified without the
<count> parameter, the command generates reports continuously. If one or more
<mount point> names are specified, statistics for only these mount points will
be displayed.  Otherwise, all NFS mount points on the client are listed.

Options:
  --version             show program's version number and exit
  -h, --help            show this help message and exit

  Statistics Options:
    File I/O is displayed unless one of the following is specified:

    -a, --attr          displays statistics related to the attribute cache
    -d, --dir           displays statistics related to directory operations
    -p, --page          displays statistics related to the page cache

  Display Options:
    Options affecting display format:

    -s, --sort          Sort NFS mount points by ops/second

nfs-kernel-server

The NFS kernel server is currently the recommended NFS server for use with Linux, featuring features such as NFSv3 and NFSv4, Kerberos support via GSS, and much more. It is also significantly faster and usually more reliable than the user-space NFS servers (from the unfs3 and nfs-user-server packages). However, it is more difficult to debug than the user-space servers, and has a slightly different feature set.

This package contains the user-space support needed to use the NFS kernel server. Most administrators wishing to set up an NFS server would want to install this package.

How to install: sudo apt install nfs-kernel-server
