I have some switchs that have dependencies on the router of its local site. I receive e-mail notifications from the switchs and router, but this is wrong, because switch trigger have a dependence from router trigger.
Let me give an example: The switch02 from SaoPaulo office is not alerting on Dashboard, what realy is down is the router, that is on Dashboard. Even with the "switch02SaoPaulo-host offline" trigger depending from "routerSaoPaulo-host offline" trigger, we receive notifications for the switch, that doesn't alert on the Dashboard or events tab!
I use Zabbix 2.4.3 on RHEL 6, but it is not listed on "Affects Version/s" field, so i used 2.4.5 .
