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).
