Triggers Dependencies

[zeeshany]

Hello,

I'm having an issue with trigger dependencies, and seeking help if someone can assist in guiding on the logic.

This is the situation

(BRANCH)----->WAN router---->INTERNET----->Cloud router----->Zabbix server

Zabbix server is hosted on cloud
Firewall device (branch site) is polled via SNMP through IPsec tunnel to Zabbix server
Firewall device has trigger-a for a WAN circuit
Firewall device also has ICMP trigger-b for local Firewall mgmt IP. trigger-b is dependent on trigger-a
Switch/Wireless controller local mgmt IP trigger-c is dependent on trigger-b.

Issue:

If WAN router goes down only the trigger-a is fired and trigger-b & c are not fired, this is ok
Once the WAN router is back, trigger-a state changes from PROBLEM to RESOLVED, immediately trigger-b is fired with PROBLEM then changes to RESOLVED after few seconds for e.g 60 secs once IPsec tunnel is established back.

question:
How can i stop trigger-b to fire?
Is there a way for trigger-b to wait for certain time, check status of trigger-a then fire?

hope I was able to explain, I hope someone can guide me to solution.

Thanks
Regards

Thanks Splitek for your response.

So for the expression, trigger-a is manually created trigger and trigger-b is template trigger. Since I want trigger-b to check itself AND trigger-a, if both return 0 then fire; I'm not able to add any expression on (trigger-b) as its inheriting from template.

Please can you guide if its possible to Add expression on host with template trigger ?
