[mrtg-developers] An exercise about Logfile.

[Yann Le Saout]

Hi,

I'm working with mrtg 2.7.2 and i've got a  problem with the log file
format.
I don't understand how mrtg generate the value for the 30 minutes
average. Don't tell me to look at the logfile-format.txt !
I've read it and read it again.
I've tried to generate the 30 minute value by myself and i've never
found the mrtg value.

Let take a exemple with this logfile:


Line 1        944607611 4007581358 3081828471
Line 2        944607611 51568 64904 51568 64904

I just want to find the value 11664 with 6 values ( which one: Line 4 to
Line 9 ?) in the beginning of the file.
Could you give me the mathematic rule which done 11664.

Thanks.
