Zabbix trigger dependency

3 Trigger dependencies (zabbix.com)

Zabbix – Router1 – Router2 – Host

If the Router1 is down, then obviously the Host and the Router2 are also unreachable, yet receiving three notifications about the Host, the Router1 and the Router2 all being down is excessive.

So in this case we define two dependencies:

the ‘Host is down’ trigger depends on the ‘Router2 is down’ trigger

the ‘Router2 is down’ trigger depends on the ‘Router1 is down’ trigger
