Hi friends, thanks for your help. When I re-read the logfiles pages, it was
clear that for detail we'll go to the backups for very-fresh logs (and

If you have backups of the log files from that day - you should be able to
that level of information.  Although I don't know how to do it.

I don't think you can do this as MRTG slowly drops the more specific 5
minute samples into 30 minute samples after 24 hours or so and then into
2 hour samples after a week or so, then finally down to 1 day samples
for the yearly data.

I think what I'm saying is that you don't have all the data you need for
that type of granularity anymore (I don't think, but if I'm wrong,
someone on the list will speak up)
