The OSGi LogService
definition is similar to the JSR47 logging framework in the sense that it does not provide separate APIs for tracing; it simply leverages the log event severity as the way to differentiate between log messages and trace messages. The LogService
defines the following levels for log messages – ERROR, WARNING, and INFO - and defines the level DEBUG for trace messages. All of the logging method signatures are valid for tracing so the information provided above is valid for OSGi tracing as well.
