+## Activating TRACE for a specific logger
+
+Sometimes it is necessary to get more detailed logs from a particular logger. For
+example, when you're trying to troublshoot an issue. Say you needed to get TRACE
+logging from the logger `org.foo`. First you would need to add `org.foo` to the
+`loggers` list at the top of `logging.properties`, e.g.:
+
+```
+loggers=...,org.foo
+```
+
+Then you need to configure the logging level for the `org.foo` logger to `TRACE`,
+e.g.:
+
+```
+logger.org.foo.level=TRACE
+```
+
+Lastly, you would need to update the `level` of the necessary `handler` to allow
+the `TRACE` logging through, e.g.:
+
+```
+handler.CONSOLE.level=TRACE
+```
+or
+```
+handler.FILE.level=TRACE
+```
