ngraph sometimes not display graph

[Frost, Mark {PBG}]

I had this same issue at first.  I later discovered that that's what the
heartbeat parameter (really an RRD parameter) in the nagiosgraph config
file is about.  I found the default value to be way too short for the
variety of checks we ran.  I read about what it did and turned the
interval up considerably and we've had nice graphs for everything we've
got for many months now.
 
I do with there was some way with Nagiosgraph to define per-check-type
heartbeat intervals rather than one interval for everything that runs in
Nagiosgraph.

	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.
	
	Ofcourse I don't know your Nagios setup, but that's my
experience with a Nagios setup with over 150 hosts and 7000 checks ;)

		Not much to go. So this question is unanswerable.
