Folks- After reading all I can, I'm still confused about dependencies. I have a setup where I have a core router ('core') and three servers... 'bob', 'jim' and 'todd', each of which is running a few services that need to be monitored. Zabbix is monitoring from the outside.
Right now, if the core router goes down, I get a million alerts... 'core' is not pingable, bob/jim/todd are not pingable, SSH is down on all the servers, HTTP is down on all the servers, etc. etc.
How can I set it up so that I just get a single alert if 'core' goes down, and if one of bob/jim/todd goes down, I just get a single alert for that (not for all the services too)? I know its got something to do with dependencies, but I can't figure it out....
