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

Alex :

What I was trying to say is that when I specified a epoch time which fell on
exactly HH:MM:00 and not HH:MM:26 (ie. had seconds aswell) it worked.
Yes, I understand my fetch syntax was incorrect and should have just specified
the -s <epoch_time> option only.

So what is it.  First you say rrdtool fetch *always* returns NaN
now you show that isn't true.


Don't shoot the messenger:  You still need to grasp the basics of
rrdtool.  RTFM, the tutorial and the faq site.

One of the questions I didn't keep in the quoted text asked for
something that, IMHO, is explained multiple times in all three
mentioned resources.

Querying "-s 1033456603 -e 1033456603" on a database with "--step 300"
shows that you don't know what you're doing.
