      @dafyre

      Both are set to 192.168.1.167 (which is internal IP of zabbix server)

      And I created inbound and outbound rules for 10050 and 10051

      Got the 10050 and 10051 open on your Zabbix server?

        Well I did this

        firewall-cmd --permanent --add-port=10051/tcp
        firewall-cmd --permanent --add-port=10050/tcp

        So I assume yes?

        How exactly would I check, sorry

          Did you

          firewall-cmd --reload ?

          Edit: That's a good question... I'm not sure about how to do that with firewalld.

                    Anyone have anymore ideas on what I should try to get the windows agent to communicate with my server?

                    Want any config files?

                          @Sparkum Finally got a windows vm setup and got the agent working.

                          alt text

                          This are the steps I took to get it working:

                          Download windows pre-compiled agent:
                          http://www.zabbix.com/downloads/3.0.0/zabbix_agents_3.0.0.win.zip

                          From an elevated cmd promt
                          I went inside the extracted folders to install the zabbix agent as a service:
                          zabbix_agents_3.0.0.win\bin\win64\

                          Executed the following command to install the service and point to the config file:
                          zabbix_agent_d.exe --config "..\..\conf\zabbix_agentd.win.conf" --install

                          Now we need to edit the config file to point to our zabbix server:
                          zabbix_agents_3.0.0.win\conf\zabbix_agentd.win.conf

                          Modify the following options:

                          Server=Zabbix Server IP Address
                          ServerActive=Zabbix Server IP Address
                          Hostname= FQDN of windows host
                          

                          Went back to the bin folder and started the service:
                          ..\zabbix_agents_3.0.0.win\bin\win64\zabbix_agent_d.exe --start

                          Allow the zabbix_agentd.exe executable throught the windows firewall.

                          Add the host to the Zabbix Server
                          alt text

                          In new host settings add:

                          # HOST TAB 
                          Host name = FQDN of your windows host
                          Groups = Use a preset group or create a new one
                          Agent Interfaces = IP address of Windows Host
                          Enabled =  Checked.
                          
                          #Templates Tab
                          Link new templates = Template OS Windows
                          

                          Save your newly created host and wait for a couple of minutes to get it talking to your server
                          alt text

                          Its done and reporting =).

                            I'm getting closer!

                            So the only thing I did from what you wrote was

                            Hostname= FQDN of windows host
                            

                            But after that I have a red Z!
                            Progress!

                            Currently getting

                             Get value from agent failed: ZBX_TCP_READ() failed: [104] Connection reset by peer
                            

                            I'll try to google my way through that now!

                            Thanks

                              I just upgraded my install from Zabbix 3.0.5 to 3.2.1 painlessly.

                              yum -y install http://repo.zabbix.com/zabbix/3.2/rhel/7/x86_64/zabbix-release-3.2-1.el7.noarch.rpm
                              yum clean all
                              yum -y upgrade
                              

                              Only poked around a little but everything seems to be working.

                              I only have 6 devices reporting in on this for the moment. Been meaning to get this fully functional for months now.

                                Same here I really need to wipe mine and re-do it all and get some better info out of it like Performance and IOPS on the servers etc, instead of just ping to see if up or down

                                  Had to modify the instructions a bit to handle SELinux. The below have been added to the first post already.

                                  Install SELinux tools.

                                  yum -y install setroubleshoot setools
                                  

                                  After your system is up and running, reboot. You should hopefully have a problem with SELinux blocking a couple of things.

                                  [root@zabbix ~]# sealert -a /var/log/audit/audit.log | grep zabbix
                                  SELinux is preventing /usr/sbin/zabbix_server_mysql from using the setrlimit access on a process.
                                  <snip lots of text>
                                  SELinux is preventing /usr/sbin/zabbix_agentd from using the setrlimit access on a process.
                                  

                                  Now that these errors are in the audit log, we can set up SELinux to allow it.

                                  If anyone knows SELinux well enough to create the policies needed without waiting for a fail, just let me know. I will be happy to update these instructions.

                                  ausearch -c 'zabbix_server' --raw | audit2allow -M my-zabbixserver
                                  semodule -i my-zabbixserver.pp
                                  ausearch -c 'zabbix_agentd' --raw | audit2allow -M my-zabbixagentd
                                  semodule -i my-zabbixagentd.pp

                                    Did anyone get Zabbix working over SSL? I'm getting a 403 error when I try to setup the certificates.

                                      I'm planning to do this and I think the best way (from what I've read) is to use a proxy to handle the SSL cert for you

                                        Does this mean proxying internal connections as well?

                                        I know Scott loves his LANLess design, so maybe my question is meaningless, because to him there is no internal?

                                          Yes, you could setup a proxy on the same box as Zabbix.

                                            Did anyone get Zabbix working over SSL? I'm getting a 403 error when I try to setup the certificates.

                                            I'm planning to do this and I think the best way (from what I've read) is to use a proxy to handle the SSL cert for you

                                            Does this mean proxying internal connections as well?

                                            I know Scott loves his LANLess design, so maybe my question is meaningless, because to him there is no internal?

                                            Yes, you could setup a proxy on the same box as Zabbix.

                                            Zabbix makes their own Proxy as well just as a side note
