NAME

       lnstat - unified linux network statistics

SYNOPSIS

       lnstat [options]

DESCRIPTION

       This manual page documents briefly the lnstat command.

       lnstat  is a generalized and more feature-complete replacement for the old rtstat program.
       In addition to routing cache statistics, it supports any  kind  of  statistics  the  linux
       kernel exports via a file in /proc/net/stat/.

OPTIONS

       lnstat supports the following options.

       -h, --help
              Show summary of options.

       -V, --version
              Show version of program.

       -c, --count <count>
              Print <count> number of intervals.

       -d, --dump
              Dump list of available files/keys.

       -f, --file <file>
              Statistics file to use.

       -i, --interval <intv>
              Set interval to 'intv' seconds.

       -j, --json

              Display only keys specified.

       -s, --subject [0-2]
              Specify  display of subject/header. '0' means no header at all, '1' prints a header
              only at start of the program and '2' prints a header every 20 lines.
