Trigger Dependency not working Agent(Not reachable)-depends on>Proxy(Not reachable)

[A_01]

I have proxy-agent relationship in which I want to make agent not reachable trigger to be dependent on proxy not reachable.
Setup we have Zabb-Prxy monitors Zabb-Agnt.

I created two triggers as follows:
On Zabb-Prxy Node: Have trigger "Agent not found for 3 minutes"

[B]Trigger Expression: [/B]{ip-10-4-1-28.ec2.internal:agent.ping.nodata(3m)}=1

On Zabb-Agnt Node:Have trigger "Agent not found for 5 minutes"

Trigger Expression: {ip-10-4-1-11.ec2.internal:agent.ping.nodata(5m)}=1
---->[B]Depends on Zabb-Prxy: Have trigger "Agent not found for 3 minutes"[/B]

I used depedency option in the create trigger window for zabb-agent to configure it as dependent on proxy.

I am gettting why is not workig as expected I am getting notification mail for both the nodes It really frustrating.

Expected / Aim : If proxy is down I should get notification mail only for proxy and not for agent.
I am referring this https://www.zabbix.com/documentation...s/dependencies


Actual: I am getting mail for both the node, Proxy is down and agent is down.
I am not what I have missed or doing worngly. Need help
Even if someone let me know how I can debug it. That will save life..
Any help greatly appreciated

Thanks in advance.
