Abstract

L'invention concerne un système et un procédé de traçage et d'évaluation de la communication d'applications logicielles, notamment d'applications MES (A1 A6) dans un système global. Lesdits système et procédé permettent un traçage et une évaluation échelonnés ou par étapes : plan de projet, plan d'adaptateur et plan de port, c.-à-d. que des liaisons de communication individuelles, des applications individuelles (A1 A6) mais aussi le système global sont tracés par l'intermédiaire de régions d'application (même hétérogènes). Les mécanismes de traçage (TB, EB) et d'évaluation (AE) permettent à des services supérieurs en ligne d'accéder à tout moment aux données de traçage et d'erreurs archivées. Un tel service pourrait se présenter sous la forme de la création d'un rapport du domaine pharmaceutique, identifiant certaines substances envoyées dans le cadre d'ordres de production.
