zabbix_get shows no return values? (windows)

[BlackCrow]

Hello!

i´m trying to geht some information from an zabbix agent using the cmd tool "zabbix_get" - but no return value is shown?

i used the following command:

C:\Programme\zabbix>zabbix_get -s 172.16.183.22 -k system.uptime

the return value is just an blank line?

has anyone an idea?


regards,

ps: i know my english is not so good but i hope you understand my problem

Hi BC,

this happens if either the Server u want to connect is not know to Zabbix ( try the zabbix hostname) or maybe an other port ?? or whatever!
Anyway you could check the RC from the zabbix_get command ( echo $? ) if this is not 0, u know there is something wrong!

hm i had a quick look at the source code :

the red code line did not return "SUCCEED" (e.g. "0")

if (SUCCEED == (ret = zbx_tcp_connect(&s, host, port, SENDER_TIMEOUT))) {
		zbx_snprintf(request, sizeof(request),"%s\n",key);
		if( SUCCEED == (ret = zbx_tcp_send(&s, request)) )
		{
[COLOR="Red"]			if( SUCCEED == (ret = zbx_tcp_recv_ext(&s, &buf, ZBX_TCP_READ_UNTIL_CLOSE)) )[/COLOR]
			{
				zbx_rtrim(buf,"\r\n\0");
				*value = strdup(buf);
			}
		}
	}
	zbx_tcp_close(&s);

i think the problem in zbx_tcp_recv_ext function is that

nbytes = ZBX_TCP_READ(s->socket, s->buf_stat, left);

returns also "0" - the application can´t read from the tcp socket?

edit: i also tryed the hostname (of the machine where the zabbix agent runs) as an parameter!
also with port number? i think it is an other problem but without any err codes from the "ZBX_TCP_READ" function...

just to be shure, the system u execute the zabbix_get command is also your Zabbix Server?
I think the zabbix_get works only from the Server.

no the machine on which i use the zabbix_get command is not the zabbix server - it´s a random winXP machine with the zabbix_get.exe (win32)

i want to get the return value from an zabbix item WITHOUT the zabbix server!

like this:

(any pc) -- [zabbix_get to get one return value] --> (win2k3 with zabbix agent)

Hi BC,

as far as i remember it's got something to do with "security" resp. known server.
You have to include the server name of the server where u use the zabbix_get in the Agent config ("Server=" parm). The agent will only satisfy to requests comming from the "known" Servers,

Hi trikke !

That was the Problem! I have added the IP from the machine where i want to use the zabbix_get.exe and it works great!

You made my day
