Timeout while executing a shell script.

[Fesenych]

Hi! I set up everything according to the instructions. I have configured one rabbitmq server. Autodiscovery found rabbitmq server, but the "RabbitMQ" stats element does not work, opposite the exclamation mark and the inscription "Timeout while executing a shell script.". I increased the timeout to 30 seconds, but the error remained. When I try to send a command from zabbix server ."/zabbix_get -s xxx.xxx.xxx.xxx -p 10050 -k "rabbitmq.stats[xxx.xxx.xxx.xxx,http://127.0.0.1:15672,guest,guest,None,example.example.ru]"", then the answer comes "OK". Hostname in Zabbix server = name in /etc/hostname on rabbitmq host = hostname in zabbix-agentd.conf
What am I doing wrong? Help please.

Hey @Fesenych How did you install the extension, from a package or manually? Does your defined zabbix server host has a correct IP address in Agent interfaces configuration section? And please can you manually perform some debug action.

• Install ngrep
• run on separate terminals ngrep port 10050 and ngrep port 10051 on monitored host (with RabbitMQ)
  If your configuration of the host in Zabbix server is correct you should see the following output

From ngrep port 10050 command:

  ZBXD.^.......rabbitmq.stats[ZABBIX_SERVER_IP,http://127.0.0.1:15672,guest,guest,None,example.example.ru] 

From ngrep port 10051

Installed manually from source following these instructions https://github.com/zarplata/zabbix-agent-extension-rabbitmq#from-source-centos-7
The agent interfaces specify IP and DNS. I tried switching between them, but it didn't help.

Zabbix agent is a passive, active server. No proxy, NAT or firewall. Other data items work without problems.
ngrep on port 10051 - no data.
ngrep on port 10051 found such records:

T ZABBIX_SERVER_IP:10051:55630 -> MONITORED_HOST_IP:10050 [AP] #14

Hmmm, so strange. As far as I see only rabbimq.discovery item key executed by zabbix-agent and no one rabbimq.stats was executed. Do you have another "UserParameters" with the same item key name rabbitmq.stats in your zabbix-agent configuration files? Check it, do `grep 'rabbitmq.stats' /etc/zabbix/zabbix_agentd.d/*'.

[Fesenych]

Checked, grep didn't return anything.

[tears-of-noobs]

@Fesenych but it should be returned at least one. This config file should be installed in zabbix-agent include dir, for example - /etc/zabbix/zabbix_agent.d (Path of the include dir depends on settings in the main zabbix-agent configuration) Check out the zabbix-agent config, it should contain Include option, for example

Include=/etc/zabbix/zabbix_agentd.d/

And the extension configuration should be placed into this include directory.

[Fesenych]

Sorry, I executed a command on another node by mistake. Here's what grep returns:
/etc/zabbix/zabbix_agentd.d/zabbix-agent-extension-rabbitmq.conf:UserParameter=rabbitmq.stats[*], /usr/bin/zabbix-agent-extension-rabbitmq --zabbix $1 --rabbitmq $2 --rabbitmq-user $3 --rabbitmq-secret $4 --ca $5 --hostname $6
