A method and device for deploying a distributed monitoring of a computer system having a plurality of resources forming at least one monitored domain. The method includes specifying for each indicator to be deployed, the domain or domains of the computer system in which each indicator should be deployed and deploying the specified configuration using a configuration deployment agent that creates, for each resource to be monitored, a configuration agent to handle the creation of the indicators.

Method and device for deploying a distributed monitoring

The present invention relates to a method and device for the scalable monitoring of a computer system comprising a plurality of computer units constituting hardware resources to be monitored forming a monitored domain, the method being implemented by means of a central computer system called a manager connected to a communication network that allows the transfer of information between at least one resource and the manager. The method comprises a step for organizing the monitored domain into monitored subdomains comprising a predetermined maximum number of resources, and a step for automatically creating and configuring, for each subdomain, an information synthesis node comprising at least one synthesis agent stored in the storage means of a resource. Each synthesis agent is designed to synthesize indicator values calculated and stored in the storage means of at least one resource. These indicators represent an operational status of the resources of the subdomain and are evaluated by indicator agents installed in these resources. Each indicator agent is uniquely identified by the name of the indicator it calculates and by the subdomain in which it is installed, and is associated with each synthesis agent using the corresponding indicator value. A further step allows for 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 new architecture of the monitored domain comprises, in each subdomain, a number of resources lower than the predetermined maximum number of resources.

Scalable monitoring method and device

The present invention relates to a method for calculating an indicator of a network management system comprising at least one submanager that monitors a part of the network. The submanager comprises a plurality of modules that allow communication with the equipment units of the network and with a main manager., At least one equation defining an indicator and evaluated by an indicator module of the submanager comprises at least one object attribute, at least one index whereof is variable. The method comprises a step for the reception by the indicator module of a notification transmitted by a model configuration module, which notification comprises an address of an equipment unit and an identification of an equation representing an indicator. The method further comprises an initialization step in which the instances of the variable indices have an initial value that does not make it possible to calculate the specified equation, and a step for determining all the valid instances of all the variable indices of all the attributes of the equation.
