 Description   

Create a host group object and name it "Chicago"
Create a host group object and name it "Firewalls"
Create a host group object and name it "switches"

Create a host and name it "firewall". Place this object in "Firewalls" and also in "Chicago"

Create a ping item and place it on the firewall host. Create a trigger with the following value:

{firewall:icmpping[].max(180)}<1

Create a host and name it "switch". Place this object in "Switches" and also in "Chicago".

Create a ping item and place it on the switch host. Create a trigger with the following value:

({switch:icmpping[].max(180)}<1 & {firewall:icmpping[].min(180)}>0)

When the switch goes offline, and is unpingable, you will see the dashboard report issues in the following host groups:

Switches, Chicago AND Firewalls.

Keep in mind, the host that has the issue (switch) is ONLY in Switches and Chicago. It is NOT a member of Firewalls.

This also is present in the 2.4 branch as well.

Comment by Oleksii Zagorskyi [ 2015 May 01 ]

Description in short, simplified:

Host groups 1,2,3

Host A member of groups 1,2
{A:icmpping[].max(180)}=0

Host B member of groups 1,3
({B:icmpping[].max(180)}=0 & {A:icmpping[].min(180)}=1)

if host B is PROBLEM then PROBLEM visible for all groups, including 2

You should know that triggers actually don't belong to hosts, they belong to items.
To the 2nd trigger related to both hosts A,B.

Both hosts have PROBLEM triggers - then all 3 groups should indicate the PROBLEM.
Nothing is wrong.

note, using <> operators in expression for icmpping[] item key (which may return only 0 or 1) - complicates reading expression logic.

We would again appreciate for reading http://www.zabbix.org/wiki/Docs/bug_reporting_guidelines#Before_reporting
Closed as won't fix.

Oleksiy, To continually infer that I don't understand how to submit a bug report is insulting and infuriating. This alienates your customer base. STOP.

I'm sorry if I said something wrong.
We have a lot of ZBX reports here, many of them appeared to be not bugs but we need to spend our time to understand that.
If people discuss their troubles on forum, IRC first - it saves our time.
That's all.
