A Logback appender that leverages syslog4j to send log messages to remote systems via syslog.
The existing syslog appender for Logback only provides the ability to send messages via UDP. Using syslog4j allows us to send messages via TCP and optionally to encrypt them by sending over TCP with TLS.
Add this to your pom.xml:
<dependency>
<groupId>com.papertrailapp</groupId>
<artifactId>logback-syslog4j</artifactId>
<version>1.0.0</version>
</dependency>Then add the appender to your logback.xml.
