LNSTAT(8)

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 results in JSON format

-k, --keys k,k,k,...
    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.

-w, --width n,n,n,...
    Width for each field.

USAGE EXAMPLES

# lnstat -d
