An operating system monitoring tool has two components: a hyperkernel (40) that augments the operating system (20) of a target multiprocessing system (10) and a graphical front end (70) for implementing the user interface (90). The hyperkernel component (40) is annexed to the operating system (20) by: intercepting all interrupts and redirecting them from the operating system (20) to the hyperkernel (40) for each point in the operating system (20) that returns back to the application code. Associated with the hyperkernel (40) are buffers (80), located on the respective processors (20), that accumulate information pertaining to calls to the operating system (20). On demand, or when the buffers fill, the accumulated information is relayed to the graphical front end (70) for filtering, manipulation, and display (100 and 110).

Outil de contrôle de système d'exploitation possédant deux éléments: un hypernoyau (40) qui augmente le système d'exploitation (20) d'un système de multitraitement (10) cible et un frontal (70) graphique destiné à implémenter l'interface utilisateur (90). Le composant constitué par l'hypernoyau (40) est annexé au système d'exploitation (20) en interceptant toutes les interruptions de programme et en les réacheminant du système d'exploitation (20) vers l'hypernoyau (40) pour chaque point dans le système d'exploitation (20) qui retourne au code d'application. Des tampons (80) sont associés à l'hypernoyau (40), lesquels sont situés sur les processeurs (20) respectifs, et accumulent des informations relatives aux appels adressés au système d'exploitation (20). Sur demande, ou lorsque les tampons sont remplis, l'information accumulée est relayée sur le frontal (70) graphique pour filtrage, manipulation et affichage (100 et 110).
