How to use

Hi,

Can you explain how to use the SMS media types?
I have done
1) config the Media type wiht /dev/ttyS0
2) Add new media type in user account
3) in "Send to" box I have written my tel number 348xxxxxxx
4) I have configured the action to send me the alarm normaly....
After this the SMS is not arrived...

I think that the problem is the GSM modem, but I don't know how to test if the GSM Modem is corectly recognized
How can I do?

How to testing

Hi,
This is a mini "How to" for GSM modem:

1) Use minicom with /dev/ttyS0 and 9600bps
2) Test some AT comand (AT, AT+CPIN?)
After
3) Read in zabbix interface Monitoring > Action, why it doesn't work.
4) Set permission "chmod 666 /dev/ttyS0"
5)Try an action...
6)GOOD LOOK

[vikty]

/dev/ttyS0 Permition deny

mmhh.. but...
Why must I do this "chmod 666 /dev/ttyS0"?
I don't think that is a normal operation...but Zabbix user can't write in /dev/ttyS0
Can someone explain me this..??

[Alexei]

Under Ubuntu, you may simply add user "zabbix" to group "dialout". No change of /dev/ttyS0 permissions is required.

[vikty]

I use Fedora Core 6...
anyway I can retry.

[vikty]

In fedora there isn't dialout group, but there is uucp group
I have tryed to add zabbix user in uucp group, but when I try to send a SMS

Error open(/dev/ttyS0) [Permission denied]

fine.. just I will find anything I will post it here...

Expected [OK] received []

After few weeks trial and doing every possible trick, ZABBIX still won't send sms out. It always return with error:
Expected [OK] received []

My GSM modem is iTegno W3800 SE with serial port. My ZABBIX hosted on FreeBSD 7.0-STABLE. ZABBIX it self have version:

ZABBIX Server (daemon) v1.4.5 (25 March 2008)
Compilation time:  May  9 2008 15:19:12

Send manual sms using AT command via minicom, no issue at all, works very charm.

i did many times recompile of sms.c, change any possible trick from step 0 till step 9 and did any advice posted in this thread but none work. ALways return with Expected [OK] received []

Is there any still possible trick for me to make it work?! What is exactly Expected [OK] received [] means?

/*  0  */       {ZBX_AT_ESC     , NULL          , 0     },      /* Send <ESC> */
/*  1  */       {"AT+CMEE=2\r"  , "OK"          , 5     },      /* verbose error
/*  1  */       {"ATE0\r"       , "OK"          , 5     },      /* Turn off echo
/*  2  */       {"AT\r"         , "OK"          , 5     },      /* Init modem */
/*  3  */       {"AT+CMGF=1\r"  , "OK"          , 5     },      /* Switch to tex
/*  4  */       {"AT+CMGS=\""   , NULL          , 0     },      /* Set phone num
/*  5  */       {number         , NULL          , 0     },      /* Write phone n
/*  6  */       {"\"\r"         , "> "          , 5     },      /* Set phone num
/*  7  */       {message        , NULL          , 0     },      /* Write message
/*  8  */       {ZBX_AT_CTRL_Z  , "+CMGS: "     , 40    },      /* Send message
/*  9  */       {NULL           , "OK"          , 1     },      /* ^Z */
/* EOS */       {NULL           , NULL          , 0     }

Error during wait for GSM modem (bit clue)

Hi,

Today i'm reproduce the error again, and capture this from log:

[COLOR="Red"]68603:20080512:102426 Error during wait for GSM modem.[/COLOR]
 68603:20080512:102426 Read from GSM modem []
]68603:20080512:102426 Write to GSM modem [
 68603:20080512:102426 Read from GSM modem []

is it because my GSM modem need a longer time to respond zabbix's initialization? Can i do increase the value of "timed_out" setting from this initialization?

Any advice?

Thanks,
BEE

Hi All
Now sms feature works for me. Nothing wrong with sms.c code. In my case, it's only serial ports configuration issue. You can find detail in my below post:

Hi,

i had the same problem.

Expected [OK] received []

The serial Interface ttyS0 was on 9600 bps.
If the speed was 9600 bps i get the failure Expected [OK] received [].

I configured the serial interface on 115200 bps.
Thats solve the problem.
Now i can send sms over the gsm modem.

Sorry for the bad english ...

Hi all,

Best thing that i have used is gnokki with this script.
Gnokki can work with any GSM device.
Within zabbix you use this script and place this script in /home/zabbix/bin
Media type is script within the user SMS +316460xxxxx 1-7,08:00-22:00; NIWAHD Enabled

#!/bin/sh

HOME=/etc
PATH=/bin:/sbin:/usr/bin:/usr/sbin
LOGFILE="/var/log/zabbix-sms.log"

echo "Recipient='$1' Message='$3'" >> ${LOGFILE}

MOBILE_NUMBER=`echo "$1" | sed s#\s##`

# Log it
echo "echo $3 | /usr/bin/gnokii --sendsms ${MOBILE_NUMBER}" >>${LOGFILE}

# Send it
echo "$3" | /usr/bin/gnokii --sendsms "${MOBILE_NUMBER}" 1>>${LOGFILE} 2>&1

# EOF

In fedora there isn't dialout group, but there is uucp group
I have tryed to add zabbix user in uucp group, but when I try to send a SMS

fine.. just I will find anything I will post it here...

zabbix_server needs to be restarted after zabbix user added to the uucp group.
