Patent ID: 7054932

Claim:
A method for scalable monitoring of a computer system comprising a plurality of computer units constituting hardware resources to be monitored forming a monitored domain, and a manager comprising a central computer system connected to a communication network that allows transfer of information between at least one of the resources and the manager, said resources including memories and having installed therein indicator agents, the method comprising: organizing the monitored domain into a plurality of monitored subdomains (d 1 , d 2 ) comprising a predetermined maximum number of resources (A 1 , A 2 , B 1 , B 2 ), providing a plurality of indicators, said indicators representing an operational status of the resources of a subdomain, specifying the subdomain(s) of the computer system in which each indicator should be deployed, automatically creating and configuring, for each subdomain, an information synthesis node comprising at least one synthesis agent stored in a memory of a resource, providing said resources with indicator agents for evaluating said indicators, each indicator agent being uniquely identified by the name of the indicator the indicator agent calculates and by the subdomain in which said indicator agent is installed, for each subdomain, associating each indicator agent with each synthesis agent using the corresponding indicator value, the structure of each synthesis agent being identical to that of an indicator agent, for each subdomain, using indicator agents for calculating and storing indicator values in the memory of at least one resource, synthesizing by each synthesis agent said stored indicator values to define corresponding indicators, and modifying the associations between the synthesis agents and the indicator agents when the predetermined maximum number of resources in a subdomain is reached, in order to accommodate the addition or deletion of indicators so that the monitored domain comprises a new architecture having, in each subdomain, a number of resources lower than the predetermined maximum number of resources.
