Abstract

La présente invention a pour objet un procédé de diagnostic, pour un système informatique comprenant au moins deux tâches (T1-T3) récurrentes appariées, comprenant les étapes suivantes : mise à jour d'un moyen de comptage d'un nombre d'occurrence dédié à une tâche (T1-T3) récurrente, lors de chaque nouvelle occurrence de ladite tâche (T1-T3) récurrente, comparaison des moyens de comptage respectifs desdites au moins deux tâches (T1-T3) récurrentes appariées avec des valeurs attendues, une incohérence d'au moins un des moyens de comptage avec sa valeur attendue étant indicative d'une erreur.
