Nagios Support Forum

We just deployed Nagios XI 2011R3.2 64-bit through a MS Virtual machine import. We added some Cisco routers to Nagios using the Network Switch/Router monitoring wizard. They've been monitored by Nagios for about 72 hours now. After looking at the graphs, we noticed that only about 1-2 hours of graphing data is displayed.

I can tell you that we adjusted the system time and date of CentOS 6.2 after adding some hosts to Nagios. Could this be our problem and if so, how can we fix without deploying Nagios again?

This could be.

You could delete the rrd's from /var/lib/mrtg/ & /usr/local/nagios/share/perfdata/ and let it start grabbing performance data over.
