Um. It would appear that you're listening on localhost:10051. In order for the agent to talk to the server it needs to be on a legitimate IP address, not a loop-back one.

Try reconfiguring your zabbix_server.conf with ListenIP commented out or set to 0.0.0.0, e.g. ListenIP=0.0.0.0

My netstat looks like this:

Code:

$ netstat -na | grep LIST | grep 1005
tcp        0      0 0.0.0.0:10050               0.0.0.0:*                   LISTEN      
tcp        0      0 0.0.0.0:10051               0.0.0.0:*                   LISTEN

Many thanks. This has fixed a number of other problems I have been scratching my head over too.

Sender problem, unrelated to other posts I've found.

i seem to be unable to get zabbix_sender to work. always returns:

Code:

"Info from server: "Processed 0 Failed 1 Total 1 Seconds spent 0.000086""

ive read pretty much everything i could find online, and all of my hostnames match up. i just set up a little test on a vm with the latest version of zabbix, and im seeing the same issue. im running logs in debug mode 4 on the server and the client, and i dont see anything that really gives an indication

Server log:

Code:

ive tried using 127.0.0.1, localhost, and centos.local with a host file entry to make it work. telnet can connect to 10050 / 10051 fine, seems the message is received, but the processing of it is failing. my zabbix_sender command is: (ive tried all combinations of -s name. localhost, centos01.local, etc)

Code:

zabbix_sender -z 127.0.0.1 -s "Zabbbix server" -k system.run[/data/check.sh] -o 2

Command output:

Code:

[root@centos01]# zabbix_sender -z 127.0.0.1 -s "Zabbbix server" -k system.run[/data/check.sh] -o 2
zabbix_sender [19613]: DEBUG: answer [{
        "response":"success",
        "info":"Processed 0 Failed 1 Total 1 Seconds spent 0.000045"}]
Info from server: "Processed 0 Failed 1 Total 1 Seconds spent 0.000045"
sent: 1; skipped: 0; total: 1

i have also set up a service_state[httpd] of type trapper and a few other of the regular checks that ship with the zabbix server, all of these produce the
same result.

the server and agent are working fine in all other aspects, only having issues with zabbix_sender. item looks OK, is of type trapper. tried all of the different information / data types (numeric, unsigned, etc), key is correct. running the script as root, permissions are OK. centos 5.5, zabbix 1.8.9.

Netstat:

Code:

[root@centos01 ~]# netstat -na | grep LIST | grep 1005
tcp        0      0 0.0.0.0:10050               0.0.0.0:*                   LISTEN
tcp        0      0 0.0.0.0:10051               0.0.0.0:*                   LISTEN

A screen capture of my item:

Also tried removing allowed hosts so its blank, but still errors.

any thoughts?

Did you ever get this one resolved?

I'm having the same problem, and there seems to be no way to find out just why it failed.

It's annoying.

**pdwalker** · 16-03-2012, 13:40

Some more information:

From the host side:

Code:

$ zabbix_sender -vv -z <zabbix-server> -s <myhost> -k unknownTriggersCount -o 0
zabbix_sender [22170]: DEBUG: answer [{
	"response":"success",
	"info":"Processed 0 Failed 1 Total 1 Seconds spent 0.000092"}]
Info from server: "Processed 0 Failed 1 Total 1 Seconds spent 0.000092"
sent: 1; skipped: 0; total: 1

From the zabbix server side (Debug=4)

Code:

 22129:20120316:112808.364 Trapper got [{ 
        "request":"sender data", 
        "data":[
                {
                        "host":"obcorp.so1",
                        "key":"unknownTriggersCount",
                        "value":"0"}]}] len 116

 22129:20120316:112808.365 zbx_send_response() '{
        "response":"success",
        "info":"Processed 0 Failed 1 Total 1 Seconds spent 0.000092"}'
 22129:20120316:112808.365 End of zbx_send_response():SUCCEED
 22129:20120316:112808.365 End of recv_agenthistory()

There is absolutely nothing in there with debugging turned on to tell me why this fails for this host, and yet succeeds for other hosts.

*sigh* Time to compile my own version of the zabbix server with special debugging code to find out why it is failing, I guess.

**MrKen** · 17-03-2012, 10:49

On the Configuration of Item screen, where it says Allowed Hosts, remove 'localhost' and enter the IP address of the host that is sending via Zabbix_Sender.

**pdwalker** · 19-03-2012, 06:00

Doh!

I set that up once and then completely forgot all about it.

Thank you!

**pdwalker** · 19-03-2012, 11:56

No,

It turns out that that was not my problem. I did have everything defined properly. I also tried leaving the "Allowed hosts"

Looking into the zabbix_server code in src/libs/zbxdbhigh/proxy.c, function process_mass_data, I found the following line:

Code:

if (SUCCEED != DCconfig_get_item_by_key(&item, proxy_hostid, values[i].host_name, values[i].key))

Adding some additional debug statements shows that this conditional is the one failing. As to why it is failing, I still don't know. As I currently understand it, it is looking for the host/item key in a cache and failing when does not find it.

It fails even though the host/item is defined and can be found in the database.

**pkhooper** · 13-04-2012, 00:03

Did you find a fix for this?

Hello pdwalker,

Did you find a fix for this issue?

I am seeing this same issue.

However, from my testing, I am not able to update any hosts via zabbix_sender.

I upgraded from 1.8.2 to 2.0rc2.

Regards,
Patrick.
