| Enable TLS secure connection | If enabled, message are transmitted securely. This certificate ensures that data transmitted between the server and clients is encrypted and secure, safeguarding it from unauthorized access and eavesdropping. | No           |
| Insecure skip verify         | If enabled, the verification of the server's certificate and hostname is skipped.                                                                                                                                | No           |
| Throttling limit             | Set a limit on the number of outbound messages per second. If sending data to a server that has restrictions on the rate of incoming messages, this ensures that no messages are lost.                           | No           |
| Persistent storage           | If enabled, messages in the outbound queue are stored on disk. If there are interruptions in connection or power loss, messages will be retained and eventually sent when the connection is restored.            | No           |
| Queue mode                   | Select the sequence of data transfer: FIFO or LIFO. Selecting FIFO (First In First Out) will send the earliest message first. Selecting LIFO (Last In First Out) will send the latest message first.             | No           |
