Connexion à une base de donnée

Quand le module mongo se connecte à une base de données, on va avoir le log suivant:

Code Block
themeEclipse
[YYYY-MM-DD HH:MM:SS] INFO : [scheduler-master] [ MongodbRetention ] [ SAVE WORKER 1 ] We are creating mongo connection [uri=mongodb://127.0.0.1/?safe=false] [database=shinken_retention] [ssh=False]

Il y indique donc:

  • L'URL utilisée
  • La base de données (peut être différente du défaut "shinken" comme ici)
  • Si un tunnel SSH va être utilisé ou pas

Sauvegarde des données

Initialisation

Avant de faire le rétention, le module nous informe de l'URI utilisée ainsi que du nombre total d'hôtes et de checks à sauvegarder.

Code Block

[2021YYYY-04MM-08DD 09HH:15MM:42SS] INFO   : [ scheduler-master ] [ MongodbRetention ] [ SAVE GLOBAL      ] Starting to save retention data with 2X worker(s). [20YY:hosts] [94ZZ:checks] (Database used = mongodb://192127.0.1680.1.31/?safe=false, use ssh = True/False)

Dans l'exemple,

  • X : Le nombre de workers lancés en parallèle pour effectuer la sauvegarde.
  • YY : Le nombre d'hôtes et clusteurs qui vont être sauvegardés.
  • ZZ : Le nombre de checks qui vont être sauvegardés.

Démarrage des workers

La sauvegarde dans la base mongo se fait avec plusieurs workers, un log par worker nous informe de son PID lors leur création.
