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.
