Large scale computer clusters have during the last years become dominant for making computations in applications where extremely high computation capacity is required. The clusters consist of a large set of normal servers, interconnected with a fast network. As each node runs its own instance of the operating system, and each node is working, in that sense autonomously, supervising the whole cluster is a challenge. To get an overview of the efficency and utilization of the system, one cannot only look at one computer. It is necessary to monitor all nodes to get a good view on how the cluster behaves. Monitoring performance counters in a large scale computation cluster implies many difficulties. How can samples of performance metrics be made...
