Abstract : Measuring performances is an important task for understanding its dynamic behavior and then to anticipate its evolution. Such task requires monitoring tools which take into account the properties both of the application and of its deployment environment, such as distribution and heterogeneity. These tools should also have as low intrusiveness as possible to avoid the disruption of the monitored system. Our contribution in this thesis is to design and implement a monitoring platform based on the dynamic deployment of probes which gather information about the use of system's resources. These probes have been chosen because of their low intrusiveness. To decrease the network exchanges, instead of transmitting data directly to the monitor each probe keeps data locally without any prior processing. The analysis treatments are postponed, and done offline. This monitoring strategy allows the optimization of bandwidth and system resources. To deal with heterogeneity, the monitoring platform includes a generic parser engine which facilitates the transformation of heterogeneous gathered data into a common format. This common format is based on XML and the correlation processing are performed at this level of genericity. This thesis defines a platform which federates probes monitoring. The concept of this solution can be extended to assist the construction of systems needing to check the status of resources. This is the case of systems that monitor performance contracts.
