That's all well and good but it doesn't directly answer my question. The question is: if a router goes down, do you get alerts for servers that are on the other side of that router, even though those servers are still up? There may be 100 server that have suddenly become unreachable. Nagios handles that with "dependencies". Perhaps Zenoss can't handle that case quite yet?
Perhaps I should have been more specific. Nagios has two states for down hosts, DOWN and UNREACHABLE. You can setup notifications to be generated for one, the other, both or none. Zenoss has two states for critical ping events, New and Suppressed. You can setup alerts to be generated for one, the other, both of none. Zenoss has the additional benefit of determining the "parent (Nagios term)" relationships automatically based on your routing tables. It also has the additional benefit of understanding multiple routes to a host can exist without failing to start do to "circular dependencies (Nagios term)." -- Chet Luther [EMAIL PROTECTED] _______________________________________________ zenoss-users mailing list [email protected] http://lists.zenoss.org/mailman/listinfo/zenoss-users
