Description

Les logs de la rétention Mongodb du Scheduler sont classés par catégorie afin de pouvoir différencier les types de log :

  • Sauvegarde
  • Chargement
  • La suppression des lignes retentions obsolètes.

Sauvegarde en rétention

Pour la sauvegarde de la rétention, trois types de logs existent: 

SectionDescription
SAVE GLOBALCorrespond au processus global de la sauvegarde
SAVE WORKERSCorresponds à un sous-processus de SAVE GLOBAL, qui s'occupe de la file d'attente des différents workers de la sauvegarde
SAVE WORKER XC'est un sous-processus de SAVE WORKERS, correspondant à un worker numéroté X qui permet de sauvegarder une partie des informations du Scheduler en base. Le nombre de workers est paramétrable dans les paramètres du module. ( voir Rétention en base de donnée centralisée par royaume ( Module MongodbRetention ) )


SAVE GLOBAL

Les logs SAVE GLOBAL donnent des informations relatives au fonctionnement global du module ou de sa configuration.

[2019-07-10 14:34:39] INFO   : [ SCHEDULERNAME ] [ MongodbRetention ] [ SAVE GLOBAL      ] Starting to save retention data. [XXX:hosts] [XXX:checks] (Database used = mongodb://HOST/?safe=false, use ssh = False)
[2019-07-10 14:34:39] INFO   : [ SCHEDULERNAME ] [ MongodbRetention ] [ SAVE GLOBAL      ] SUCCESS Retention data was saved into mongodb. Total time X.XXs


Erreurs

Les erreurs lors de la sauvegarde de la rétention sont aussi enregistrées dans les logs sous cette forme: 

[2021-04-20 11:26:57] ERROR  : [ scheduler-master ] [ MODULES-MANAGER  ] The instance MongodbRetention raised an error: [ SAVE GLOBAL      ] FAILED Retention data could not be saved in mongodb. Total time 22.20s. I disable it and set it to restart it later


Lors de la sauvegarde de la rétention, la base mongo est injoignable 

[2021-04-20 11:26:57] ERROR  : [ scheduler-master ] [ MODULES-MANAGER  ] The instance MongodbRetention raised an error: [ SAVE GLOBAL      ] FAILED Retention data could not be saved in mongodb because mongo is unreachable. Total time 2.11s. I disable it and set it to restart it later


SAVE WORKERS

Les logs SAVE WORKERS donnent l'état de chaque worker de sa création à son succès/échec.

[2019-07-10 14:34:44] INFO   : [scheduler-master] [ MongodbRetention ] [ SAVE WORKERS                ] Starting worker 0 with pid 14746. Try: 1/3

[2019-07-10 14:34:44] INFO   : [ SCHEDULERNAME ] [ MongodbRetention ] [ SAVE WORKERS                ] some workers did fail to exit or encountered an error. The retention save can be incomplete.
[2019-07-10 14:34:44] ERROR  : Too many tries failed
[2019-07-10 14:34:44] ERROR  : Cannot start the XXXXX worker process as there is not enough memory

SAVE WORKER X

Les logs SAVE WORKER X donne pour le worker ayant l'identifiant X, les statistiques sur les sauvegardes qu'il a effectuées : le nombre d'éléments, résultat et temps d'exécution.

[2019-07-10 14:34:44] INFO   : [ SCHEDULERNAME ] [ MongodbRetention ] [ SAVE WORKER 0          ] Updating retention with elements: checks [ XXX ] -- hosts [ XX ] in mongodb
[2019-07-10 14:34:44] INFO   : [ SCHEDULERNAME ] [ MongodbRetention ] [ SAVE WORKER 0          ]  Retention data saved into mongodb in X.XXX seconds
[2019-07-10 14:34:44] INFO   : [scheduler-master] [ MongodbRetention ] [ SAVE WORKER 0          ] Will save 249 hosts and 249 checks

Erreurs


[2019-07-10 14:34:44] WARNING: [ SCHEDULERNAME ] [ MongodbRetention ] [ SAVE WORKER X          ] The worker (pid:XXXX | try:XX) did not exit on time (XX s). We are restarting it.


En cas d'erreur, chaque worker essaiera de se lancer à nouveau en respectant le nombre de tentatives maximales définies dans le fichier de configuration du module. Si la rétention n'est pas sauvegardée après ces tentatives, le module sera en échec et le Scheduler s'arrêtera.
Lorsque le SSH tunnel est activé :

Chargement de la rétention

Les logs fournissent des informations liées au chargement de la rétention, permettant de suivre son avancée et l'état sur la connexion à Mongo.
