Pour @Animal et notre cozo.

Merci à Liandri pour le lien.

Principe :

• Vous installez le serveur Glowroot quelque part.
• Sur vos serveurs de production, vous ajoutez un agent Java à la ligne de commande de démarrage de vos JVM.
• Vous n'oubliez pas de faire pointer votre agent Java vers vos serveur Glowroot.

=> Vous obtenez automatiquement un système de monitoring. GG

D'autre systèmes :

• Pinpoint.
• Arthas de la société Alibaba.

Merci encore une fois à Philou pour le lien (tu es en train de devenir ma nouvelle source de merveilles techniques).

Pour Animal et la gestion de nos VPS.
