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 ;) <pre class="moz-signature" cols="72">----------------------------------- Jeffrey Lensen System Administrator Hyves hyves page: <a class="moz-txt-link-freetext" href="http://skyler.hyves.nl">http://skyler.hyves.nl</a> mail/msn: <a class="moz-txt-link-abbreviated" href="mailto:jeffrey@hyves.nl">jeffrey@hyves.nl</a> </pre> Hugo van der Kooij wrote: <blockquote cite="mid:Pine.LNX.4.64.0705110718070.21890@faramir.hugo.vanderkooij.org" type="cite"> <pre wrap="">On Thu, 10 May 2007, hendro budianto wrote: </pre> <blockquote type="cite"> <pre wrap="">I'have a problem with nagiosgraph display.
