Gestion des logs AMETHYST

=Préambule=
Par défaut les logs générées par Mapping sont dans un format propriétaire Mapping afin que celles-ci puissent être lu par l'interface de MAPPING. Il est possible de les transformer en texte grâce à la commande map_log_txt mais il est impossible de modifier leur formatage.
Grâce à Améthyst, il est possible de générer des logs avec un formatage paramétrable et vers différents médias possibles.
L'activation d'Améthyst et la déactivation de l'ancien système de log améliorent également les performances.
=Limitations=
Améthyst est en constance évolution. La sortie 9.1.0 inclus la possibilité d'utiliser Améthyst uniquement pour les exécutions du workflow. (Binaire map_809)
Des évolutions permettront l'utilisation d'Améthyst avec d'autres binaires. (mapcpysplf, map_lpr et autres)

=Liste des médias possibles=
Les médias de sorties de logs sont :
* Fichier texte
* La console invoquant le traitement
* Une requête HTTP

=Prérequis=
* Onyx Server v9.1.0 minimum

=Paramétrage=
Pour activer les logs Amethyst il faudra procéder à des modifications 
==mapping.conf==
#Aller dans le bloc '''LOGS'''
#Ajouter les paramètres suivants
*LOG_TYPE
**'''Default''' : Utilisation de  l'ancien système de log Mapping
**'''Amethyst''' : Utilisation du nouveau système de log Mapping (Améthyst)
**'''All''' : Utilisation des deux systèmes de logs (Ancien et Améthyst)
*PATH_AMETHYST_LOG
**'''Chemin du fichier de configuration d'Améthyst'''

==config.yaml==
Améthyst a besoin d'un fichier de configuration, qui part défaut, s'appelle config.yaml et se situe dans le répertoire conf ou settings de MAPPING. Son nom et chemin sont spécifiés dans le fichier mapping.conf dans la partie LOGS avec le paramètre '''PATH_AMETHYST_LOG'''
Ce fichier de configuration est au format yaml et inclus les configurations des Loggers du nouveau système de logs

=Focus sur le fichier config.yaml=
Voici la description du fichier de configuration :
==config==
* '''config'''
:* '''server'''
::* port: le port du serveur de logs.
::* threads : le nombre de threads utilisés par le serveur (max 250)
==loggers==
:* '''loggers'''
::* '''source''' : le nom de la source des logs récupéré par les programmes (`workflow` est le nom du logger du map_809)
::** Workflow
::* '''level''' : le niveaux minimum de logs
::** debug
::** information
::** warning
::** error
::* '''channels''' : la liste des channel qui indique le type de logs
:::* '''type''' : indique le type de channel
==FileChannel==
:::* '''path''' : indique le chemin du fichier de log généré (Dans le cas du Type = FileChannel)
::::* Chemin du fichier de log généré
:::* '''rotation''' : Indique la fréquence de génération de nouveau fichier de log (un fichier par jour, par mois, par semaine...)
::::* never: no log rotation
::::* [day,][hh]:mm: the file is rotated on specified day/time day - day is specified as long or short day name (Monday|Mon, Tuesday|Tue, ... ); day can be omitted, in which case log is rotated every day hh - valid hour range is 00-23; hour can be omitted, in which case log is rotated every hour mm - valid minute range is 00-59; minute must be specified
::::* daily: the file is rotated daily

::::* <n>: the file is rotated when its size exceeds <n> bytes.
::::* <n> K: the file is rotated when its size exceeds <n> Kilobytes.
