lnstat - unified linux network statistics

lnstat [ options ]

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/.

These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). 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.

-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.

# lnstat -d

    Get a list of supported statistics files.

# lnstat -k arp_cache:entries,rt_cache:in_hit,arp_cache:destroys

    Select the specified files and keys.

# lnstat -i 10

    Use an interval of 10 seconds.

# lnstat -f ip_conntrack

    Use only the specified file for statistics.

# lnstat -s 0

    Do not print a header at all.

# lnstat -s 20

    Print a header at start and every 20 lines.

# lnstat -c -1 -i 1 -f rt_cache -k entries,in_hit,in_slow_tot

    Display statistics for keys entries, in_hit and in_slow_tot of field rt_cache every second.
