turned the interval up considerably and we've had nice graphs for everything

<DIV></DIV>My experience with having Nagios creating graphs, is the problem
that checks don't manage to finish in time, which creates faulty data in the
RRD database. RRD has to receive new data at a certain time-interval in order
to create proper RRD files. Since the execution time of Nagios checks can be
somewhat unpredictable at times, it tends to not be able to do this in
time.<BR><BR>Ofcourse I don't know your Nagios setup, but that's my experience
with a Nagios setup with over 150 hosts and 7000 checks ;)<BR><PRE class=moz-signature cols="72">-----------------------------------

<BLOCKQUOTE type="cite"><PRE wrap="">I'have a problem with nagiosgraph display.
Some times the graph is display (have a data) but
after a few minutes there are no data to display.It's
something wrong with my nagios setting ?
I've check the ngraph.log but everything is OK, the
REGEX grub the result to rrd file.
Any suggestions ?

Not much to go. So this question is unanswerable.
But about a year ago I wrote about a number of things which seem to have
an impact on the proper working of ngraph.
