NAME

       nfsdclnts - print various nfs client information for knfsd server.

SYNOPSIS

       nfsdclnts [-h] [-t type] [--clientinfo] [--hostname] [-q]

DESCRIPTION

       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

       -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.
