How to make triggers automatically dependent on the availability of the Default Gateway?

Question

Zabbix

There are several dozen remote offices. Using ICMP ping in Zabbix I monitor internet access from these remote offices (by pinging routers over the internet).

If the channel drops at the point where the Zabbix server is installed, then the ping will not go through to all other remote offices, triggers will be triggered about the unavailability of routers in all remote offices.

You can make triggers dependent on another trigger (which will work if it doesn't ping to 8.8.8.8 or the provider's gateway and disable other triggers).

How to massively assign the dependency of other triggers to this trigger?

How to assign a dependency of triggers in all subnets except the current one depending on the availability of the provider's gateway?

Answer 1

Found a solution.
1. Create a "provider router"
node 2. Apply the standard "Template Module ICMP Ping" template to the "provider router" node
3. Remove unnecessary Items and Triggers from the "provider router" host
4. Clone the Template Module ICMP Ping template and name it ICMP Ping Internet Group
5. In the Triggers of the ICMP Ping Internet Group template, on the Trigger tab, change "Unavailable by ICMP ping" Add a dependency (Dependencies tab) on the Unavailable by ICMP ping trigger of the "provider's router" host
6. Apply the created template to a group of nodes on the Internet that need to be monitored.
