 Description   

I've a problem configuring an action on a trigger with multiple items on different hosts.
If I try to send a message, I receive the email without problem but if I try to run a remote command, I receive the following error:

Too many hosts in a trigger expression

Too many hosts in a trigger expression

Comment by Alexei Vladishev [ 2012 Nov 22 ]

How the command is defined? What macros does it use?

Comment by Leonardo Bargagni [ 2012 Nov 22 ]

Each trigger that snaps, run a remote command (wpostemsg with parameters) to send the alarm on a console for ced operators.
The command works properly if the trigger item refers to a single server.
If we check if a process is running on at least one server of two, when the trigger fires, Zabbix returns the error (Too many hosts in a trigger expression)

The problem is also present on the 2.4 version.
Is there any news?

Comment by Xavier Qu [ 2015 Mar 01 ]

I have the same problem.
I created a trigger where trigger expression contains different hosts. And I want to zabbix server execute some script (with contains macros like

{HOST.NAME1}

{HOST.NAME2}

) when the trigger fires.
It works when expression contains only one host(even multiply items), but I get "Too many hosts in a trigger expression" when different hosts.
The items are in active mode.
Zabbix server v2.2.6 (revision 48483) (27 August 2014)

Can anyone tell me if I misuse the function or it's zabbix's bug?

Comment by Alexander Vladishev [ 2015 Mar 04 ]

It will be fixed under ZBX-9352.
