Logstash: l’arme secrète pour vaincre le coté obscur de vos logs

Talk given at Devoxx France 2015

http://cfp.devoxx.fr/2015/talk/LMO-2774/Logstash:_l%E2%80%99arme_secrete_pour_vaincre_le_cote_obscur_de_vos_logs

Les logs générés par vos applications, services, systèmes d’exploitations et équipements réseaux (soit toutes les composantes nécessaires au fonctionnement des systèmes d’information) sont typiquement une masse obscure de données non-structurée et décentralisée. La nature non structurée de cette information la rend chaotique et pratiquement incompréhensible.

Grâce à sa flexibilité et sa simplicité, Logstash vous permet de transformer cette information non-structurée en données structurées, indexables et analysables.

Venez découvrir comment l’outil Open Source Logstash peut vous aider à collecter et transformer les streams de données hétérogènes, décentralisées et non-structurées tels que les logs, pour passer du mode réactif de la recherche de la cause à la visualisation et l’analyse pro-active, en temps-réel, de vos données opérationnelles.
