A computer system is disclosed that involves multiple communicatively interconnected computers, a Monitoring and Control Program (MCP) on each node, wherein each MCP is communicatively interconnected to other MCPs, wherein at least one of the MCPs acts as a controlling MCP, wherein the controlling MCP will execute, and communicate, operating system-independent MCP control language commands to other MCPs to at least cause the other MCPs to monitor execution of the transactions of the production workloads across the nodes, on a per-transaction basis, with each MCP monitoring individual transaction execution on its node in real-time, and wherein, in conjunction with the monitoring, the MCPs will collectively generate a transaction table, on a node and transaction basis, detailing parametric information regarding the execution of the transactions across the nodes, with at least one of the MCPs effecting storage of the transaction table.
