Hi everyone,

I installed a poller on a Raspberry Pi 4. The Centreon central server is hosted on a VM (so they are not on the same local network).

After creating the poller, I ran the following command:

bash /usr/share/centreon/bin/registerServerTopology.sh -u <API_USER> -t poller -h <CENTRAL_IP> -n <POLLER_NAME>

The poller appears in the Centreon interface. I selected it, copied the configuration provided by the interface, applied it to the Raspberry Pi, then restarted Gorgone on both sides. I also exported the configuration from Centreon.

But the poller still doesn't run.

In the Gorgone logs, I see the following message:
ERROR - [proxy] Send message problem for '8':

Do you think this could be the issue?

Thanks in advance for any help.

hi, 

could the centreon central reach your poller with the gorgone port?

Hi,

Thanks a lot for your reply!

From the Centreon Central server, I tried telnet <poller_IP> 5556 → Connection refused immediately.
From the poller, I tried telnet <central_IP> 5669 → Connection successful, but closed by foreign host right after.

Here are the open ports I can see using netstat or ss:

 On the poller:

tcp 0 0 0.0.0.0:5556 0.0.0.0:* LISTEN

This shows that Gorgone is listening on all interfaces (0.0.0.0) on port 5556.

 

 On the central:

tcp 0 0 0.0.0.0:5669 0.0.0.0:* LISTEN tcp 0 0 127.0.0.1:38752 127.0.0.1:5669 ESTABLISHED tcp 0 0 127.0.0.1:5669 127.0.0.1:38752 ESTABLISHED

So Centreon-Broker is listening on port 5669, with a local established connection between two processes.

Let me know if there's anything specific I should try or check next.

Thanks again for your help!
