       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


       These programs follow the usual GNU  command  line  syntax,  with  long
       options  starting with two dashes (‘-’).  lnstat supports the following

       -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.
