       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
