Log Sending
In the Log Sending tab, you can transmit Surveillance Station logs to a syslog server.
To send logs to a syslog server:
- Go to Log > Log Sending, and tick the Send logs to a syslog server checkbox.
- Enter the hostname or IP address of the server in Server.
- Enter the specified port number for receiving syslog messages in Port. This should match the port number of the syslog server.
- Select UDP or TCP from the Transfer protocol drop-down menu. This should match the protocol used by the syslog server.
- Select BSD (RFC 3164) or IETF (RFC 5424) from the Log format drop-down menu to send logs using the selected format.
- If you select TCP as the transfer protocol and want to secure the syslog connection with SSL, tick the Enable secure connection (SSL) checkbox and click Import certificate to ensure logs are securely transferred to the syslog server.
- Click Save to apply settings.
- Click Send test log to confirm the syslog server can receive the log successfully. If the syslog server does not receive the test log, please make sure your settings are correct.
Notes:
- By default, the port is 514. Proper port forwarding rules must be set if you want to reassign a different port number to the syslog server.
- UDP (User Datagram Protocol) is a more simplified message-based connection protocol that is faster but lacks security and error correction. TCP (Transmission Control Protocol) offers guaranteed delivery, in which it uses flow control to determine whether all the packets have been successfully sent before new ones are processed.
- Secure connection (SSL) can only be enabled when TCP is used.
- The Log Center package can be installed on your Synology NAS, allowing it to be used as a syslog server to view the received logs.
