Run remote command on trigger

[rocklee44]

Hi all,
I'm using Zabbix 2.4 to monitor nodejs service on a server, I want Zabbix Agent can restart service when trigger on "service down"
/etc/passwd
zabbix:x:498:498:Zabbix Monitoring System:/var/lib/zabbix:/sbin/nologin
I want Zabbix agent can run this command as userA:
/path-to/forever restart /path-to/nodejs.js
How should I configure action : Target list , Type , Commands
And visudo ?
Thanks for your help.

If you want execute that command line by userA, you must settng change shell and visudo.
At first, you must change shell for zabbix user.

　# usermod -s /bin/sh zabbix

Next, some setting change by visudo.

Add 2 lines :
-----
zabbix ALL=(userA) NOPASSWD:/path-to/forever restart /path-to/nodejs.js
Defaults:zabbix !requiretty
-----

And, EnableRemoteCommands value set to 1 in zabbix_agentd.conf.
-----
EnableRemoteCommands=1
-----

After that, you can add Action setting.

example value:
Operation type : Remote command
Type : Custom script
Execute on : Zabbix agent
Commands : sudo -u userA /path-to/forever restart /path-to/nodejs.js

You can add top of the trigger action (Configuration -> Action -> triggers)

In Action definition Trigger name and exact template or host name and in Operations tab: Operation type -> Remote command and here you can choose execute action on zabbix agent or server.

To be honest I think that it would be good if it would be possible to define actions on template/host level as well.
