Zabbix Server Trapper problem

[ShadowMonster]

Hi
I'm new with Zabbix so sorry if this problem is dump. I install Zabbix on Ubuntu 12 with kernel 3.2 - Everything work fine expect one thing. When from Screen view I try ping my host it show me error:
ERROR: Cannot connect to the trapper port of zabbix server daemon, but it should be available to run the script.
and then below:
Undefined index: data [include/classes/api/CAPIObject.php:44]
Invalid argument supplied for foreach() [include/config.inc.php:457]

Server and Agent work fine but this trapper maybe not I not fully understand it yet.

Can someone give me advise why it happen?

Thanks

Can someone at least give me some direction what can cause this problem please?

Thanks

Can you check the configuration of your "ping" script, under Administration -> Scripts? See if the actual ping command is correct. Mine is:

/bin/ping -c 3 {HOST.CONN}

[ShadowMonster]

Thanks for answer.

Mine is /bin/ping -c 3 {HOST.CONN} 2>&1 I test it on server on shell and command is correct.

This error looks more on some kind problem with php or something.

That actual error is generated by zabbix/www/scripts_exec.php. I wonder if you could run zabbix with debug logging and see if there's more info in the server log..

[ShadowMonster]

Can you direct me how to turn on debug for it - I have some logs on but there is only about executing housekeeper in /var/log/zabbix-server in agent just about turn on/off agent process

[dougbee]

There's a section in /etc/zabbix/zabbix_server.conf (assuming that's your config file) :

### Option: DebugLevel
# Specifies debug level
# 0 - no debug
# 1 - critical information
# 2 - error information
# 3 - warnings
# 4 - for debugging (produces lots of information)
#
# Mandatory: no
# Range: 0-4
# Default:
# DebugLevel=3

You can set the DebugLevel=4 and restart the zabbix server process. And it will indeed produce LOTS of info!

[ShadowMonster]

Thanks for this info.
Yes it generate a lot stuff anyway I catch some

What I was able found is this:

29019:20120920:173715.920 In DBget_trigger_update_sql() triggerid:100100000013487 value:0(0) new_value:0
29019:20120920:173715.920 End of DBget_trigger_update_sql():FAIL
29019:20120920:173715.920 In DBget_trigger_update_sql() triggerid:100100000013488 value:0(0) new_value:0
29019:20120920:173715.920 End of DBget_trigger_update_sql():FAIL

I'm not sure if this related to it but I cannot find any other errors or fails...
Do you know maybe as what I should look for it?

Lol I found it!

It was my mistake in zabbix.conf.php of front end.

in this line:
$ZBX_SERVER_PORT = '10051';

I use 10050 with was wrong. Now ping and other work good

I have a similar problem, but the scripts work perfectly after I restart the zabbix server daemon and stop to work after 30 minutes showing the message below:

"ERROR: Cannot connect to the trapper port of zabbix server daemon, but it should be available to run the script.
Error description: defined in "include/defines.inc.php" constant ZBX_SCRIPT_TIMEOUT timeout is reached. You can try to increase this value."

I have no idea to find a solution for this problem. Someone can help?

My environment:

Red Hat 6 using other physical host with orcale 10G
Zabbix server 2.0.3
