Problems creating a new script media type

[jarenas]

Hello, I'm trying to create a script that receive a phone number as a parameter from zabbix and write this phone number in a text file.

I'm doing this for testing purpose only, because after that, I will create a script that will call using my pbx.







$1 must be my phone number passed as a parameter when the script is executed after an alert.




After an alert other scripts that I downloaded from the Internet are working fine, but my script doesn't work. It have to create a new txt file but it doesn't work.

What am I doing wrong?

Thanks, I'm a newbie with zabbix.

Regards!

Hello,

You must set you script executable:
chmod +rx test.sh

There is no capital X option for chmod command. Please execute the command all in lowercase.

Before moving forward please execute the script from command line:
./test.sh 12345678

Hi thanks, I did everything and works in the shell, but not with zabbix alerts.



It says that was sent, but the script wasn't executed, there is not any txt file in the folder.

Hello,

Try with full path saving it to /tmp
echo "$1" >> /tmp/test.txt

What operating system are you running? if CentOS then SELinux may block your file creation.
Take a look at current SELinux status:
sestatus
You can temporary turn off SElinux with:
setenforce 0
..and turn it back with:
setenforce 1

Thanks for comment, yes, selinux is disabled, and I have tried with full path to /tmp and the same problem, the script is not executed.

Hello,

Please make sure the /tmp/test.txt file do not exist before trying scenario in zabbix. If you test scenario in direct shell then /tmp/test.txt will be owned by root. When you run alerter from zabbix server it is executed by user zabbix, but zabbix user cannot write to file which is owned by root.

Can you show permissions of?
ls -l /var/zabbix/
ls -l /var/zabbix/alertscripts

These directories also should be owned by zabbix
chown -R /var/zabbix

Now it works! It was a folder permission problem
