DESCRIPTION         top

       The nfsdclnts(8) command parses the content present in
       /proc/fs/nfsd/clients/ directories. nfsdclnts(8) displays files
       which are open, locked, delegated by the nfs-client. It also
       prints useful client information such as hostname, clientID, NFS
       version mounted by the nfs-client.

OPTIONS         top

       -t, --type=TYPE
           Specify the type of file to be displayed. Takes only one TYPE
           at a time.

           open, lock, deleg, layout, or all

           open: displays the open files by nfs-client(s).

           lock: displays the files locked by nfs-client(s).

           layout: displays the files for which layout is given.

           deleg: displays delegated files information and delegation
           type.

           all: prints all the above type.

       --clientinfo
           displays various nfs-client info fields such as version of
           nfs mounted at nfs-client and clientID.

       --hostname
           Print hostname of nfs-client instead of ip-address.

       -q, --quiet
           Hide the header information.

       -v, --verbose
           Verbose operation, show debug messages.

       -f, --file
           Instead of processing all client directories under
           /proc/fs/nfsd/clients, one can provide a specific states file
           to process. One should make sure that info file resides in
           the same directory as states file. If the info file is not
           valid or present the fields would be marked as "N/A".

       -h, --help
           Print help explaining the command line options.
