I don't know about your case, but what I do here if there are multiple devices which support a single address is put all of them in Nagios as Assaf mentioned. I'll then set the "real" hosts as the parents of the virtual one, and if things are set up that way you *don't* need to worry about setting downtimes for the virtual address, because it will automatically be marked unreachable if all of the real addresses are down. In my case, though, I primarily want to know if the VIP is working, and am not quite as concerned with the individual hosts serving it (though those are important as well, just not as important as if the service they provide is available). Based on your statement that you'd "have to monitor another host," it sounds like knowing the state of this service isn't really as important to you as knowing if the individual hosts that serve it are working. Frankly, that seems a bit backwards to me, but I don't really know your environment. ------------------------------------------------------------------------------ _______________________________________________ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null
