Therefore, initializing the logging in Saros comprises the steps:
1. The default log4j2 initializing is executed that uses the configuration file `log4j2.xml` (has to be included in the classpath).
2. Our custom initializing starts:
* We determine the IDEs log directory and the required log level (e.g. `all` if Saros is running the debug-mode).
* We determine the IDEs log directory and the required log level (e.g. `debug` if Saros is running the debug-mode).
* We set the main arguments `logLevel` and `logDir`.
* We force log4j to reinitialize with the log configuration `saros_log4j2.xml` that uses the defined arguments ( with the format `main:<argument>`).

See the initializing in the classes [`Saros`](https://github.com/saros-project/saros/blob/master/eclipse/src/saros/Saros.java) (in Eclipse)
or [`SarosComponent`](https://github.com/saros-project/saros/blob/master/intellij/src/saros/intellij/SarosComponent.java) (in IntelliJ)
for example implementations. Sometimes (as in the Saros Server) using the default initializing is enough.

### Settings a different log level during development

Sometimes you might have the need for a different log level during development, e.g. if you are interested in `trace` level logging.
To adjust the log level, you can modify the `root` log level in the `Loggers` section of the `saros_log4j2.xml`.
