[rrd-users] Re: MRTG base --> RRDtool calculation base value

[Tobias Oetiker]

Yesterday you sent me mail regarding [rrd-users] MRTG base  -->  RRDtool...:

*> I am constructing a traffic monitoring/billing system using
*> RRDtool and Perl, replacing a system based on MRTG.  I am
*> therefore in the process of comparing RRDtool graphs to MRTG
*> graphs, and have come up with the following question.
*> 
*> RRDtool has a default calculation base of 1000, which the manual
*> states is correct for network traffic, but that the base can be
*> changed to 1024 for purposes of graphing memory.  I know a KByte
*> is 1024 Bytes, and that is the unit for traffic, so why would
*> 1000 be correct for traffic?  Is it that 1000 as a unit is
*> correct for traffic in bits/Kilobits/Megabits versus bytes?
*> 
*> Also, does MRTG use 1000 as a calculation unit when graphing, or 1024?

1 Kilo equals 1000 (in telecomunication as well as elsewhere in the
world) only memmory comes in 1024 = 1000

and yes mrtg does it with 1000 too (it can be switched to 1024 as
well)
