MRTG, or PNP/RRD? It is normally for graphs not to show right away, since there isn't any data to graph yet. If they still don't show up after the system has been running for a while, you may need to try resetting your security credentials as outlined on http://support.nagios.com/wiki/index.ph ... #No_graphs
