Studies dealing with tuning, performance debugging and diagnosis in cluster environments largely benefit from in-depth knowledge
of memory system information. In this paper a tool (called MemTo) for monitoring the behavior of the memory system through a Linux cluster is presented. MemTo has been designed to have as low intrusiveness as possible while keeping a high detail of monitoring data. The good behavior
and usefulness of this tool are proved experimentally.
