Hi Everyone
The problem:
- I have a few Linux machines (one of which for this example we will call empies) connecting to my server (called gaddafi) with OpenVPN.
- Because of this configuration, the reachability of empies is dependent on whether gaddafi itself is reachable or not. I mean, there is no way for the VPN to be connected if the VPN server itself is down.
- When you don't configure dependencies in nagios properly, when gaddafi goes down, I will also get notifications for empies (and the 30 odd other devices connecting to gaddafi via VPN). I would like to prevent that from happening by defining service dependencies for each VPN client to tell nagios that they are all dependent on gaddafi being up.
I have to following configuration for my nagios that doesn't work. It still sends out notifcations for both Ping services for each host if I filter all icmp packets to empies.
From the documentation as I understand it, when the service Ping on gaddafi is in a c (critical) state, then it should not send out notifications for the service Ping on empies, but it definitely does. Can someone please show me an example of how this should be done?
