-== Introduction to APEX Logging
-
-All APEX components make extensive use of logging using the logging façade link:https://www.slf4j.org/[SLF4J] with the backend link:https://logback.qos.ch/[Logback].
-Both are used off-the-shelve, so the standard documentation and configuration apply to APEX logging.
-For details on how to work with logback please see the link:https://logback.qos.ch/manual/index.html[logback manual].
-
-The APEX applications is the logback configuration file `$APEX_HOME/etc/logback.xml` (Windows: `%APEX_HOME%\etc\logback.xml`).
-The logging backend is set to no debug, i.e. logs from the logging framework should be hidden at runtime.
-
-The configurable log levels work as expected:
-
-- __error__ (or __ERROR__) is used for serious errors in the APEX runtime engine
-- __warn__ (or __WARN__) is used for warnings, which in general can be ignored but might indicate some deeper problems
-- __info__ (or __INFO__) is used to provide generally interesting messages for startup and policy execution
-- __debug__ (or __DEBUG__) provides more details on startup and policy execution
-- __trace__ (or __TRACE__) gives full details on every aspect of the APEX engine from start to end
-
-The loggers can also be configured as expected.
-The standard configuration (after installing APEX) uses log level __info__ on all APEX classes (components).
-
-The applications and scripts in `$APEX_HOME/bin` (Windows: `%APEX_HOME\bin`) are configured to use the logback configuration `$APEX_HOME/etc/logback.xml` (Windows: `%APEX_HOME\etc\logback.xml`).
-There are multiple ways to use different logback configurations, for instance:
-
-- Maintain multiple configurations in `etc`, for instance a `logback-debug.xml` for deep debugging and a `logback-production.xml` for APEX in production mode, then copy the required configuration file to the used `logback.xml` prior starting APEX
-- Edit the scripts in `bin` to use a different logback configuration file (only recommended if you are familiar with editing bash scripts or windows batch files)
