Monitoring resource utilization in distributed systems remains of importance. This is especially the case in LAN-based distributed systems (and, in particular, in global Grid systems), where individual nodes can be (may need to be) added to and/or removed from the system at “random” moments. The aim of this paper is to report initial results of the project that aims at using Erlang-based software agents as a robust and flexible resource monitoring infrastructure. The implemented prototype is capable not only of collecting performance data, but can also detect certain network problems. Furthermore, an assessment of the eXAT agent platform, based on experiences gathered during prototype implementation, is included.
