Why doesn't Zabbix 3.0 pass parameters $1,$2,$3 to the script?

Question

linux

There is Zabbix 3.0 on Ubuntu 14.04. Got an API from SMS.RU to send SMS.
Created a script in /usr/local/share/zabbix/alertscripts. Here is the content of the script:

#!/bin/bash
# SMS.RU sender for zabbix
api="133C1FB3-8D01-DD1C-90BA-********"
to="$1"
subject="$2"
body="$3"
curl -d "text=$body" http://sms.ru/sms/send\?api_id=$api\&to=$to

Added execution rights to the script (chmod +x /usr/local/share/zabbix/alertscripts/zabbix-sms).
In zabbix itself, I set up all the alerts and added the {ALERT.SENDTO}, {ALERT.SUBJECT}, {ALERT.MESSAGE} parameters to my script. When the trigger fires, Zabbix reports that the notification has been sent, but nothing comes up.
When executing the script from the console, it gives 203 alert - no message text. Replacing the values ​​of $1, $2, $3 with their own (I wrote hello in the body of the letter), SMS began to arrive. How would I do it now, so that I would receive trigger values, and not hello ))
I ask for your help, because I have little experience with the work of Zabbix, as well as with programming.

Answer 1

Problem solved! The problem was that I ran the script from under the bash and, accordingly, it did not receive parameters from Zabbix (because I used the bash standard input / output stream). For performance, it was necessary to initiate the execution of the script by Zabbix or add variables when executing the script in the bash. For Zabbix 3.0 it was easy to add {ALERT.SENDTO}, {ALERT.SUBJECT}, {ALERT.MESSAGE} values ​​in Media Types to your script.

Answer 2

And why did you put the parameters in quotation marks?
to="$1" => to=$1

Answer 3

Maybe someone will need my version of the script for sending through the site sms.ru

#!/bin/bash
# SMS.RU
#Задаём переменные
api="Тут должен быть API"
phone="$1"
text="$2"
body="$3"
LOG="/var/log/zabbix/SMS.log"

# Делаем запись даты в лог
echo >> $LOG
echo -e "                             \e[1;32m --=START=--\e[m" >> $LOG
echo >> $LOG
echo -e "                   \e[1;33m -=`date`=-\e[0m" >> $LOG
echo >> $LOG
#Записываем в лог, что передаёт ZABBIX в скрипт.
echo " Заголовок сообщения" >> $LOG
echo -e "\e[1;36m $body\e[0m" >> $LOG
echo " Текст сообщения" >> $LOG
echo -e "\e[1;36m $text\e[0m" >> $LOG
echo " Телефон получателя" >> $LOG
echo -e "\e[1;36m $phone\e[0m" >> $LOG
echo >> $LOG
#Посылаем СМС
curl -d "text=$body" http://sms.ru/sms/send\?api_id=$api\&to=$phone >> $LOG
echo -e "\e[1;34m <-ответ от СМС шлюза\e[0m" >> $LOG
echo >> $LOG
echo -e "                             \e[1;31m --=FINISH=--\e[m" >> $LOG
echo"===================================================================================================================" >> $LOG
#Смотреть логи в цветном виде можно командой вида : tail -n 19  *Путь к файлу*.log

The response from the server is also written to the Log, which will help to diagnose malfunctions faster
. Here is an example of a log output

Answer 4

Use ${1} instead of $1

Answer 5

In the server config, does the path to the directory with the alert scripts exactly match your /usr/local/share/zabbix/alertscripts?
Well, this ... try to remove the extra quotes, yes. Or use single ones in curl.
