MRTG-LOGFILE(1)			     mrtg		       MRTG-LOGFILE(1)

NAME
       mrtg-logfile - description of the mrtg-2	logfile	format

SYNOPSIS
       This document provides a	description of the contents of the mrtg-2
       logfile.

OVERVIEW
       The logfile consists of two main	sections.

       The first Line
	   It stores the traffic counters from the most	recent run of mrtg.

       The rest	of the File
	   Stores  past	 traffic  rate	averages  and  maximum	at  increasing
	   intervals.

       The first number	on each	line is	a unix time stamp. It  represents  the
       number of seconds since 1970.

DETAILS
   The first Line
       The first line has 3 numbers which are:

       A (1st column)
	   A  timestamp	 of  when  MRTG	 last  ran  for	 this  interface.  The
	   timestamp is	the  number  of	 non-skip  seconds  passed  since  the
	   standard UNIX "epoch" of midnight on	1st of January 1970 GMT.

       B (2nd column)
	   The "incoming bytes counter"	value.

       C (3rd column)
	   The "outgoing bytes counter"	value.

   The rest of the File
       The  second  and	 remaining  lines of the file contains 5 numbers which
       are:

       A (1st column)
	   The Unix timestamp for the point in time the	data on	this  line  is
	   relevant.   Note  that the interval between timestamps increases as
	   you progress	through	the file. At first it is 5 minutes and at  the
	   end it is one day between two lines.

	   This	 timestamp  may	be converted in	OpenOffice Calc	or MS Excel by
	   using the following formula

	    =(x+y)/86400+DATE(1970;1;1)

	   (instead of ";" it may be that you have to use "," this depends  on
	   the context and your	locale settings)

	   you can also	ask perl to help by typing

	    perl -e 'print scalar localtime(x),"\n"'

	   x  is  the  unix timestamp and y is the offset in seconds from UTC.
	   (Perl knows y).

       B (2nd column)
	   The average incoming	transfer rate in bytes	per  second.  This  is
	   valid  for the time between the A value of the current line and the
	   A value of the previous line.

       C (3rd column)
	   The average outgoing	transfer rate in bytes per  second  since  the
	   previous measurement.

       D (4th column)
	   The	maximum	 incoming  transfer  rate  in bytes per	second for the
	   current interval. This is calculated	from  all  the	updates	 which
	   have	occurred in the	current	interval. If the current interval is 1
	   hour,  and  updates	have  occurred every 5 minutes,	it will	be the
	   biggest 5 minute transfer rate seen during the hour.

       E (5th column)
	   The maximum outgoing	transfer rate in  bytes	 per  second  for  the
	   current interval.
