    Active agent works on Appliance 3.2 but not on Zabbix 3.2 Centos7

    Hi

    Running two versions of Zabbix in-house. First the zabbix appliance (version 3.2). We have successfully got zabbix agents communicating with the zabbix applince server, both active and passive. Because of the limitations of the zabbix appliance i've installed zabbix (3.2) on a centos7 server and was starting to transfer the setup from the appliance server to the full server. Everything seemed to be working fine until i started to switch the active zabbix agents across. None of them seem to be ableto communicate with the new server (passive agenst are fine). Repointing these active agents back to the appliance server works as well. The error shown on the zabbix server is
    "Get value from Agent Failed:cannot connect to [[0.0.0.0]:10050]:[111] Connection refused".

    Upping the log level on the agent shows that data seems to be being transmitted from the agent, also the agent seems to be picking up the templates from the server, but the server just seems to think it cannot connect. I've tried disabling both Selinux and firewalld on the zabbix server but still no luck. I can ping the agent OS from the server and can ping the server from the agent OS (all the agents are installed on Windows OS). I can telnet from the agent OS to the server and get a connection. I'm not sure where the issue lies here. Can anybody suggest how to troubleshoot this or has come across this issue before ?

      can you try re-installing the agent ?
      and try to telnet between agent and server to see port 10050 is open
      telnet $ZABBIXSERVERIP 10050 --> from agent machine
      telnet $AGENTSERVERIP 10050 -->> from zabbix machine.

      see zabbix server logs with debug level 4

          Hi
          So i can telnet from the Agent to the zabbix server (on port 10050) and get a response, and i can telnet from the server to the agent (on port 10051) and get a response.

          Logs from the agent show that it picks up template changes - snip here:

          From these logs i cannot see a lot wrong. Can anybody spot anything ?. Would there be any error codes or messages that i could search for perhaps ?

          Thanks

          Roger

              So i can telnet from the Agent to the zabbix server (on port 10050) and get a response, and i can telnet from the server to the agent (on port 10051) and get a response.

              From these logs i cannot see a lot wrong. Can anybody spot anything ?. Would there be any error codes or messages that i could search for perhaps ?

              Thanks

              Roger
              i dont see that your error repeat -
              "Get value from Agent Failed:cannot connect to [[0.0.0.0]:10050]:[111] Connection refused".
              do you still have it ?
              what is the issue now ?

              i dont spot any error from the logs all look like it works fine

                  Hi
                  Yes, issue is still the same. Just wondering if there is something in the Centos7 minimal build that may be stopping something, or perhaps it's something to do with the build level of zabbix ad tne pre-req's, though when i built it all the pre-reqs showed green ticks. And the active agents work ok on a zabbix appliance server on the same network and the centos7 zabbix server. Pretty much stumped for a solution at the moment.

                      did you disabled Selinux ?

                          On first loo seems like you have still type of the items on this host not as "zabbix agent (active)" but "zabbix agent".
                          On change from passive agent to active one you must change types of the items.

                              Hi

                              SELinux is disabled (and so is firewalld). As regards the active vs passive checks. I can point the agent to a zabbix appliance server and it is monitored correctly, both the zabbix servers are on the same network (and in the same subnet). I would have thought that if the passive vs active checks was the cause it would be the same for both servers ? (maybe not). I've done this the same way for a few zabbix appliance servers now (at different sites) and all the appliance servers are ok. This is my first attempt at a full zabbix server build and everything works apart from the active checks, which is quite frustrating.

                              How would i go about removing the passive checks (there are not many - the only template being applied is the Windows OS one).

                                  G list of items of your Windows template -> mark all "zabbix agent" items in template -> mass update and change type to "zabbix agent (active)"
