Next, the unit conversion definition generation unit 602 classifies each node for each item recorded in the configuration information 610. First, the unit conversion definition generation unit 602 classifies each node based on the IP address. Next, the unit conversion definition generation unit 602 classifies each node based on the service ID 613. Next, the unit conversion definition generation unit 602 classifies each node based on the software name 614 (step S613).
  • the unit conversion definition generation unit 602 obtains the number of elements of each classification item based on the information of each node classified in step S613 (step S615). For example, referring to the example of the operation step, the unit conversion definition generation unit 602 has three nodes belonging to the space whose IP address is “128.6.1. ***” based on the configuration information 610. There are three nodes belonging to the service ID 613 “service001_e_commerce”, two nodes belonging to the “AP layer”, and one node belonging to the “DB layer”. Here, “***” means an arbitrary value (0 to 256).
  • the unit conversion definition generation unit 602 outputs the information collected up to the previous step as the space definition 130 (step S617).
  • FIG. 7 is an example of the space definition 130 output by the unit conversion definition generation unit 602. As described above, the unit conversion definition generation unit 602 can output the space definition 130.
  • the same effect as that of the above embodiment can be obtained. Further, based on the service level definition 110 and the configuration information 610, time can be automatically set. Definition 120 and space definition 130 can be output. This is because the unit conversion definition generation unit 602 outputs the time definition 120 and the space definition 130 based on the service level definition 110 and the configuration information.

Abstract

L'invention concerne un dispositif de gestion de niveau de service (100) comprenant une unité d'analyse (106), une unité d'agrégation (102) et une unité de calcul de niveau de service (104). Ladite unité d'analyse (106) analyse une table de définition de niveaux de service (110), et d'après une table de définition de conversion d'unités (108) qui définit une relation entre des unités d'agrégation avec différents attributs, définit plusieurs niveaux de service différents ayant le même attribut et différentes unités d'agrégation, et définit une unité d'agrégation de groupement qui regroupe des unités d'agrégations ayant le même attribut. Ladite unité d'agrégation (102) trouve une valeur agrégée pour les données de gestion. D'après plusieurs tables de définition de niveaux de service (110), ladite unité de calcul de niveau de service (104) calcule un niveau de service à partir de la valeur agrégée. L'unité d'agrégation (102) regroupe les données de gestion pour chaque unité d'agrégation de groupement afin de trouver la valeur agrégée. D'après la valeur agrégée pour chaque unité d'agrégation de groupement, l'unité de calcul de niveau de service (104) calcule le niveau de service défini par les multiples tables de définition de niveaux de service (110).
