I have been trying to setup Zabbix to monitor my 2 tomcat servers on 2 different Amazon EC2 machines, but in vain. 

 The Z on the host is green, however te JMX is red with these errors   

- ZBX\_TCP\_READ() failed: [4] Interrupted system call   

- Someother error [111] connection refused
and many such errors, one after another, in the sense I resolve an error to see one more new error popping up.

These are some assumptions   

All the machines run Ubuntu 12.10 and later   

**Server's IP address:** 66.55.12.120 (Runs Zabbix server v2.2.4 (revision 46772) (23 June 2014) )   

**Agent's IP address:** 87.52.45.198 ( Runs Zabbix agent v2.2.2 (revision 42525) (12 February 2014) )   

**My local machine's IP address:** 76.89.54.111   

Here is what I've done so far.

***On Server Side:***   

1) Installed Zabbix\_server using `sudo apt-get install zabbix-server-mysql.`   

2) The GUI, mysql database all have been installed and configured.   

3) The following are the only 3 changes that I've made in the file   
 `/etc/zabbix/zabbix_server.conf`

```
  ... 
  JavaGateway=localhost
  JavaGatewayPort=10052
  StartJavaPollers=5
  ...

```

4) The Zabbix Java gateway was installed using `sudo apt-get install zabbix-java-gateway.`  

5) The following are the only 3 changes that I've made in the file   

`/etc/zabbix/zabbix_java_gateway.conf`

```
  ... 
  LISTEN_IP="127.0.0.1"
  LISTEN_PORT=10052
  START_POLLERS=5
  ...

```

***On Client Side:***
1) Installed Zabbix Client using
 `sudo apt-get install zabbix-agent`   

2) The following are the only 3 changes that I've made in the file   

```
  /etc/zabbix/zabbix_agentd.conf 
  ... 
  Server=66.55.12.120
  StartAgents=5
  ServerActive=66.55.12.120:10051
  Hostname=Security-test-JMX-EC2
  ... <br />

```

3) The Hostname is the same as the one that is mentioned while creating the Host on the GUI.   

I believe that there are some issues with the IP and ports. So, here are the outbound rules for both the machines as obtained from Amazon EC2 Security Groups for the machines

```

What am I missing? Please guide me.
Any help is appreciated.   

Thanks
