The paper presents a brief overview of the SMEDL monitoring system that provides flexible and scalable deployment of monitors for large-scale software. The SMEDL specification language expresses monitoring logic as a collection of monitoring objects and monitoring architecture as flows of information between the monitored system and monitoring objects. The system supports synchronous as well as asynchronous deployment of monitoring objects and dynamic instantiation of monitoring objects on demand. The application of the SMEDL system for the monitoring of a target tracking application is briefly discussed.
