NAME

       nfsvis - visualize performance of NFS statistics

SYNOPSIS

       nfsvis [-V] [-c version] [-m maxrate] [-s version] [pmview options]

DESCRIPTION

       nfsvis  displays  a three dimensional bar chart of NFS request statistics.  The display is
       updated with new values retrieved from the target host or archive every  interval  seconds
       (default is 2 seconds).

       Two blocks of statistics are displayed - one for the NFS server and one for the NFS client
       requests.  The height of the bars is proportional to the rate at which the various request
       types are processed.

       nfsvis  generates  a pmview(1) configuration file, and passes most command line options to
       pmview(1).  Therefore, the command line options -A, -a, -C, -h, -n, -O, -p, -S, -t, -T, -Z
       and -z, and the user interface are described in the pmview(1) man page.

COMMAND LINE OPTIONS

       The nfsvis specific options are:

       -c     Monitor NFS version 2 or 3 client metrics.  The default is version 2.

       -m     Use maxrate as the maximum NFS request rate over all classes of request, from which
              the height of the bars is computed.  This effectively specifies the height at which
              bars will be clipped.

       -s     Monitor NFS version 2 or 3 server metrics.  The default is version 2.

       -V     Verbose mode - output the generated pmview(1) configuration file.

FILES

       $PCP_VAR_DIR/config/pmlogger/config.nfsvis
                 A pmlogger(1) configuration file for nfsvis metrics.
       $PCP_SHARE_DIR/lib/pmview-args
                 Shell procedures for parsing pmview(1) command line options.

PCP ENVIRONMENT

       Environment variables with the prefix PCP_ are used to parameterize the file and directory
       names used by PCP.  On each installation, the file /etc/pcp.conf contains the local values
       for  these  variables.   The  $PCP_CONF  variable  may  be  used to specify an alternative
       configuration file, as described in pcp.conf(4).
