To configure syslog-ng on a relay host, complete the following steps:
Procedure 3.6. Configuring syslog-ng on relay hosts
Install the syslog-ng application on the host. See Chapter 4, Installing syslog-ng for details installing syslog-ng on specific operating systems.
Configure the network sources that collect the log messages sent by the clients.
Create a network destination that points to the syslog-ng server.
Create a log statement connecting the network sources to the syslog-ng server.
Configure the local sources that collect the log messages of the relay host.
Create a log statement connecting the local sources to the syslog-ng server.
Set filters and options (e.g., TLS encryption) as necessary.
In relay mode, syslog-ng cannot write messages received from network sources into
files; the file() destination is disabled. The following sources
are network sources: tcp(), tcp6(),
udp(), udp6().
