Logging to system streams

Question

I'm using Websphere Liberty 8.5.5 on Linux and I'm trying to redirect its logging into Unix syslog. The logging configuration in the server.xml has an entry for copySystemStreams="true", which according to the documentation for the server.xml logging should have the following behaviour: "If true, write System.out to the system output stream and System.err to the system error stream. If false, System.out and System.err will write to configured logs like messages.log or trace.log, but not to the system streams. The default value is true."

However, I do not see any Liberty entries in syslog if I set copySystemStreams to true. Am I misunderstanding the documentation or is this a missing piece of functionality?

Answer 1

Check this page from the Liberty documentation Liberty profile: Logging and Trace, it has newer, more accurate description of this field. So it will not log to the syslog, no matter what is set in copySystemStreams.

copySystemStreams

If true, messages written to the System.out and System.err streams are copied to console.log. If false, those messages are written to configured logs such as messages.log or trace.log, but they are not copied to console.log. The default value is true.
