====== File log4j.properties ======
Il file log4j.properties, è utilizzato per configurare le modalità di logging in geoweb.

Si possono specificare, tra l'altro, Logging Level selettivamente e su quali file verranno salvati i log.
Per una guida completa fare riferimento a quella ufficiale [[https://logging.apache.org/log4j/2.x/manual/configuration.html|qui]].

===== Logging Level =====
Impostando un logging level, si avrà come effetto quello di visualizzare loggati solo i messaggi di pari livello o superiore.
Ecco la lista dei logging level, in ordine crescente dal meno al più restrittivo:
  * **ALL**		All levels including custom levels.
  * **DEBUG**		Designates fine-grained informational events that are most useful to debug an application.
  * **INFO**		Designates informational messages that highlight the progress of the application at coarse-grained level.
  * **WARN**		Designates potentially harmful situations.
  * **ERROR**		Designates error events that might still allow the application to continue running.
  * **FATAL**		Designates very severe error events that will presumably lead the application to abort.
  * **OFF**		The highest possible rank and is intended to turn off logging.
Altri:
  * **TRACE**		Designates finer-grained informational events than the DEBUG.


Per quanto riguarda in Geoweb, è buona prassi impostare il logging level a DEBUG in fase di sviluppo/dispiegamento in ambiente di test/collaudo, ed ad WARN od ERROR in produzione.

Log generati da librerie di terze parti, come Activti e MongoDB vengono in genere tenuti sempre con logging level più restrittivi, come ERROR, a meno di specifiche necessità di debugging.

I log relativi al GwMailService sono in genere configurati per essere loggati su un file separato.
