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

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.

USAGE EXAMPLES

# 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.
