       Usage: rtacct [ -h?vVzrnasd:t: ] [ ListOfRealms ]

DESCRIPTION

       nstat and rtacct are simple tools to monitor kernel snmp counters and network interface statistics.

OPTIONS

       -h -?  Print help

       -v -V  Print version

       -z     Dump zero counters too. By default they are not shown.

       -r     Reset history.

       -n     Do not display anything, only update history.

       -a     Dump absolute values of counters. The default is to calculate increments since the previous use.

       -s     Do  not  update  history, so that the next time you will see counters including values accumulated to the moment of this measurement
	      too.

       -d <INTERVAL>
	      Run in daemon mode collecting statistics. <INTERVAL> is interval between measurements in seconds.

       -t <INTERVAL>

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 sup-
       ports any kind of statistics the linux kernel exports via a file in /proc/net/stat/.

OPTIONS

       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.
