Zabbix 1.4.4 SMS not working

[johanpre44]

I have a Fedora 7 Box with Zabbix installed (from Fedora Repo) and configured to send emails/SMS's. Emails working fine, but the actins tab reports and error:
"Expected [OK] received [úAT+CMEE=2ERROR]"

Changing the Deguglevel to 4 (for zabbix_server) and checking the log files, I get these lines:
27360:20080108:163224 Write to GSM modem [ESC]
27360:20080108:163224 Write to GSM modem [AT+CMEE=2^M]
27360:20080108:163224 Read from GSM modem [ESC<FA>ESCAT+CMEE=2^MERROR^M]
27360:20080108:163224 Write to GSM modem [^MESC^Z]
27360:20080108:163224 Read from GSM modem []
27360:20080108:163224 Query [update alerts set retries=retries+1,error='Expected [OK] received [ESC<FA>ESCAT+CMEE=2ERROR]' where alertid=5254]

Using Minicom I do get an error if I "AT+CMEE=2"

But I can execute the following commands in Minicom without problems:
AT
OK
AT+CMGF=1
OK
AT+CMGS="xxxyyyzzzz"
> testing123
>
+CMGS: 17
AT
OK

Please help
PS: My GSM/SMS device (Teltonika TModemCOM) is based on the Nokia i12 Engine.

Some More info

AT+CMEE=1 in minicom returns an OK.

According to an AT command reference for GSM devices, it seems that all AT+CMEE=2 does is set the Error messages to Verbose rather than Numeric (Don't think my Device supports it then) - AT+CMEE=? returns the support Error messages, which is only 0 and one for my device.

How can I change this?

i've had such error as you.
my solution is to modify in .../zabbix-1.4.4/src/libs/zbxsms/sms.c this line:
{"AT+CMEE=2\r" , "OK" , 5 },
to
{"AT+CMEE=2\r" , "ERROR" , 5 },
and recompile...
works great

I have the same problem. I tried what you said and now i get this instead.

Expected [ERROR] received [AT+CMEE=2]

what can i do the get this working. I am at a lose.

Thanks for any help.

[alexander]

if you had
Expected [SOMETHING] received [EXAMPLE]

you should try to modify in .../zabbix-1.4.4/src/libs/zbxsms/sms.c this line:
{"AT+CMEE=2\r" , "SOMETHING" , 5 },
to
{"AT+CMEE=2\r" , "EXAMPLE" , 5 },
and recompile... it should works... SOMETHING AND EXAMPLE are strings that zabbix expected and recived (look in your error message for details)


how it works?
zabbix writing AT commands to modem and wait for modem's answer, then compare answer to value which writen in .../zabbix-1.4.4/src/libs/zbxsms/sms.c
Some commands like AT+CMEE=2 are not critical for sending sms, some are critical, so if you got such error, then modify code and zabbix says that sms sended, but you don't recive it it's mind that command, wich you modify is critical and problem is in your gsm-modem setup...

sorry for my english =)

sms

Hi,

I have the same problem.

I have correctly connected my gsm modem and i can send sms manually in the console, but zabbix can not send my sms.

I can not understand the solution for this.

What is the file to repair the values of the gsm modem, it is necessary to recompile?

Thanks

SMS: Hint for the developers

Hi

this won't help you guys today, but maybe you and others in the future.

Years ago I had to support a software which waits for calls on a modem line.
Not that much different than sending SMS but much
less complex than that, indeed.
In order to support different modem types I used the library "terminfo"
so the user could specify a known type of modem or even add a new specification for his model.

I know, there is a software library called "modemcap" (like termcap for
terminals) which should do the trick. But either terminfo or termcap is
available on most Linux/UNIX Systems, anyway.

I suggest using one of these libraries in the future instead of hard-coded
request/response strings which fail for some modems but work
for others. Well designed, this will reduce the number of problems by
just adding one more (optional ?) dependency of the server on another library.
I think it's worth thinking about and implementing it !

Regards

Norbert.

to alexander, THANKS !! SMS now works fine!.

[ufocek]

Hi

I configured my gsm modem Hueawai E220, zabbix send me sms but in action "status table" all the time status is "not sent" but I received sms
Zabbix get error: Expected [+CMGS: ] received [] or Expected [OK] received []

this is a bug or something else?

2danic:
"I have correctly connected my gsm modem and i can send sms manually in the console, but zabbix can not send my sms."

what zabbix says in monitoring / actions ?

"Telepathists in holiday" (с) linux.org.ru

"What is the file to repair the values of the gsm modem"
/<path to zabbix sourcecode>/src/libs/zbxsms/sms.c

"it is necessary to recompile?"
Yes, if you will use my solution.

2ufocek:
"I have question where I can put pin code permanently to gsm modem?"

AT+CPIN="<code here>"

"this is a bug or something else?"
Ask developers =) i think my solution should help with your troubels

2John Yta:
you're welcome

2all: sorry for my english ))

Would be good if the developers hade a text file that we could add with the AT commands we wanted to be used to access all kind of different GSM modems out there.

Not everyone is compiling zabbix froum source some are installing from RPM's and cant recompile it.

Kinda old thinking to force peopel to change the source code and recompile to get there modems to work.

And Zabbix 1.4.4 dont report any errors in log files regarding SMS send errors.!

still not works

Hi,
I just got iTegno WM1080A1E for my ZABBIX server. My ZABBIX running under FreeBSD 6-STABLE, and i successfully send a sms from minicom using /dev/cuad0.
Unfortunetly, opposite happen with zabbix and the sms alert never reach my mobile phone.
I have follow what alexander said:
1.

change {"AT+CMEE=2\r"  , "OK"       , 5     } to {"AT+CMEE=2\r"  , "ERROR"       , 5     }

2. try to comment out {"AT+CMEE=2\r" , "ERROR" , 5 }.

       zbx_sms_scenario scenario[] = {
/*  0  */       {ZBX_AT_ESC     , NULL          , 0     },      /* Send <ESC> */
/*  1   {"AT+CMEE=2\r"  , "ERROR"       , 5     },      verbose error values */
/*  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     }
                };

3. do configure and make && make install

but still never received sms, is there something that i miss?

Thanks,
BEE

Hi,
is there any comment or clue?i'm getting very frustration with it. Most of suggested way had been tried without no luck, and now i do upgrade my zabbix server to:

ZABBIX Server (daemon) v1.4.4 (17 December 2007)
Compilation time:  Feb  8 2008 17:10:42

but again, have no luck.

What did i miss?

Thanks,
BEE
