Aggregate multiple interfaces/services/hosts

[Kimberly McKinnis]

Could you use the check_dns plugin? Then if you couldn't resolve the host through either interface, it would alarm. It doesn't require an expected-address. I check a round-robin DNS entry this way, making sure it just resolves to something.

Subject: [Nagios-users] Aggregate multiple interfaces/services/hosts

Hello,

I would like to monitor a couple of devices ( servers and witches) that are connected to the network via at least two interfaces. Nagios server is connected as well over two interfaces to the LAN. My question is:

Is there any way to aggregate the monitored services/hosts into a single object that gives the critical status only when all aggregated objects have this status?

For example: the Nagios system has two network interfaces: 192.168.0.1 and 192.168.1.1. I would like to monitor a DNS server connected to the network via 192.168.0.2 and 192.168.1.2 IP addresses. Of course I can reach the DNS server from Nagios two ways: either via the 192.168.0.1 interface or via 192.168.1.1. My target is to issue a warning/critical signal only when Nagios cannot query the DNS server on none of the IP addresses. Same should apply for hosts and network equipment and the service group should also provide performance data.

I have already gave a shot with Nagios BPI, but unfortunately I cannot use the service group to map it in PNP4Nagios.
