Overview

Zabbix supports the sending of SMS messages using a serial GSM modem connected to Zabbix server’s serial port.

Make sure that:

• The speed of the serial device (normally /dev/ttyS0 under Linux) matches that of the GSM modem. Zabbix does not set the speed of the serial link. It uses default settings.

• The ‘zabbix’ user has read/write access to the serial device. Run the command ls –l /dev/ttyS0 to see current permissions of the serial device.

• The GSM modem has PIN entered and it preserves it after power reset. Alternatively you may disable PIN on the SIM card. PIN can be entered by issuing command AT+CPIN=“NNNN” (NNNN is your PIN number, the quotes must be present) in a terminal software, such as Unix minicom or Windows HyperTerminal.

Zabbix has been tested with these GSM modems:

• Siemens MC35

• Teltonika ModemCOM/G10

To configure SMS as the delivery channel for messages, you also need to configure SMS as the media type and enter the respective phone numbers for the users.

Configuration

To configure SMS as the media type:

• Go to Administration → Media types

• Click on Create media type (or click on SMS in the list of pre-defined media types).

The following parameters are specific for the SMS media type:

See common media type parameters for details on how to configure default messages and alert processing options. Note that parallel processing of sending SMS notifications is not possible.

User media

Once the SMS media type is configured, go to the Administration → Users section and edit user profile to assign SMS media to the user. Steps for setting up user media, being common for all media types, are described on the Media types page.
