[rrd-users] Re: RRD Fetch always shows Nan

Alex :

Thank you for your help with this and the constructive comments.  I have read
the tutorial and followed the examples and it worked great :)
Coming back to my original question is that from looking @ my existing data each
line is seperated by 5 mins, what I cannot understand
is why no data appears in the database.  I am trying to grasp the principles of
how it all works and appreciate your help and the lists help
in getting to know it better.

Many thanks

Phil

If you are surprised that is the case then you lack knowledge.
And no, this does not mean you need to do the updates on n*300.

No.

I'm not going to explain to you personally what I already
explained multiple times in the tutorial, the faq site and many
other posts on this list.  This discussion ends here.
