you can use adaptive monitoring too, where state change in one of the check (the first ip check) will trigger further checks (second ip check); You can chart the performance data by enabled process_performance_data and related configuration and then using nagiosgraph or pnpgraph . Optionally if you have a splunk installation you can use splunk also to graph the performance data regards ranjib <div class="gmail_quote">On Mon, Jul 11, 2011 at 6:27 AM, <<a href="mailto:Radu.Popa@technomatic.de" target="_blank">Radu.Popa@technomatic.de</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Hello and thank your for your answer! The plugin should be really good for any service, but what about graphing the perf data? Let's take the following example: 1 server has two IPs: 192.168.1.1 and 192.168.2.1 I would like to monitor the CPU load via wmi queries on the machine. I would like to be able to get it first over the 192.168.1.1 and if it fails, it should be queried the next interface, 192.168.2.1. If that one fails, it should be put in the critical state. As as result I should obtain performance data from any interface which is available or a critical status. The perf data can be used later to be graphed in PNP4 Nagios for example. Ideas? Thank you!

Each system has two NICs, so two IP addresses. I would like to setup Nagios in such a way that when I want to see if a host is up for example, it should ping first on ti's first IP and if failed, try the second IP. Only if the second attempt is failing it should declare the host unreachable. Same should apply for other services monitored as well: CPU usage, memory usage aso. Can this be achieved in order not to have duplicate states for each machine?
