  • (the host) for UDP, e.g. 127.0.0.1 or some.host.com
• port (Optional): Port, default 12201
• originHost (Optional): Originating Hostname, default FQDN Hostname
• extractStackTrace (Optional): Post Stack-Trace to StackTrace field, default false
• filterStackTrace (Optional): Perform Stack-Trace filtering (true/false), default false
• mdcProfiling (Optional): Perform Profiling (Call-Duration) based on MDC Data. See MDC Profiling, default false
• facility (Optional): Name of the Facility, default gelf-java
