Hi all,
I've a question concerning the graph function of rrdtool. Please
look at this part of rrdtool DB dump:
<!-- Round Robin Database Dump -->

The point I want to move on foreground is at 2001-03-13 13:42:00 where
the value is at 100 (1e+02).
When I graph it using the "rrdtool graph" command line, even if I
use the CF (LAST or MAX), this point never appears in my graph.
(they are joined to this mail).
So my question is:
Does it be that I use a Bad CF on the creation of my rrdtool DB ?
If yes, how can I migrate my databases ?
Does it be a bug of rrdtool on my OS ?
informations:
OS: Solaris 2.6 Generic_105181-23 sun4u sparc SUNW,Ultra-60
rrdtool:RRDtool 1.0.24
thanks in advance,
any help appreciated, Freddy.
