# Appendix 5 - Logback configuration

### Default configuration

By default the Batch Service produces the application log on standard output and file. 

* The log level is `INFO`
* The log file is saved in the default LOGS directory with the name `application.log`
*  The file rotation policy is:
  * daily: every day a new log file is created 
  * size capped: the maximum size of log file is 10MB, after that the log file is gzipped and renamed with a progressive number as suffix

### Customization

It is possible to customize the log level, the subfolder and the name of the application log and the pattern of the logs with the environment variables listed in the section *1. Logging* in [Appendix 6](/centrostella-1/centro-stella/instructions-for-agenzia-delle-entrate-mandate/appendixes/appendix-6-configuration-properties.md).
