Syslogrelay provides system log forwarding facility for confined environments, such as docker containers. It listens for incoming system log messages on the UNIX socket file /dev/log and forwards them to the specified remote server. The following transport protocols are supported: traditional UDP (RFC 5426), legacy TCP (RFC 6587), and TLS over TCP (RFC 5425).

The relayed messages are normalized to make sure they comply with RFC 5424. In particular, hostname is added if necessary. This is important in docker environments, since otherwise the collector would insert the IP address of the container or gateway in place of the missing hostname, and neither IP is informative enough to identify the container where the message originated.
