The Distributed Measurement Laboratory (DML) is an heterogeneous system and the workload evaluation is an important aspect to support the performance management strategies in the case the specific requirements must to be respected. The paper describes the method to evaluate the workload of the cooperating hardware equipments of the DML, in particular: (i) the connecting networks, and (ii) the PCs. In this manner useful indexes are achievable to monitor the functioning conditions of the whole DML. The proposed method is based on three different tools known and tested in literature. The first one concerns with the synchronization among the clocks of the different cooperating PCs. The second one concerns the One-Way Delay parameter measurements of the path from the source to the destination. The third one concerns the workload measurement of the CPU of each PC. The results of several experimental tests showing the performance and the accuracy of the method are shown.
