Logging¶
Unity Catalog uses Log4j 2 logging framework (through the Simple Logging Facade for Java (SLF4J) with Apache Log4j SLF4J 2.0 Binding).
There are two logging configuration files in etc/conf:
| Component | Configuration File |
|---|---|
| Unity Catalog CLI | etc/conf/cli.log4j2.properties |
| Unity Catalog Server | etc/conf/server.log4j2.properties |
etc/conf/server.log4j2.properties¶
Unity Catalog Server uses etc/conf/server.log4j2.properties logging configuration file.
The following sample server.log4j2.properties sets up logging to standard output (console):
status = warn
appender.console.name = stdout
appender.console.type = Console
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = %d{YYYY-MM-dd HH:mm:ss} [%t] %-5p %c:%L - %m%n
appender.console.target = SYSTEM_OUT
rootLogger.level = info
rootLogger.appenderRefs = console
rootLogger.appenderRef.console.ref = stdout
