Method for building enterprise scalability models from production data

A computer program product adaptable for storage on a computer readable medium and operable for creating a discrete event simulation model comprising the program steps of:

• gathering resource data from a plurality of resource monitors operatively disposed on a plurality of servers resident on a multi-tiered system executing a business function;
• wherein the resource data includes a reporting interval, a timestamp, a resource utilization, a received packet count and a sent packet count;
• equalizing at least one reporting interval in the resource data;
• synchronizing at least one time stamp in the resource data;
• normalizing at least one set of units in the resource data;
• calculating a resource consumption for the plurality of servers;
• calculating a transaction cost from the resource data;
• approximating a transaction flow for a plurality of transactions related to the business function;
• calculating a network throughput between the plurality of servers;
• and
• building a discrete event simulation model from the transaction cost, the transaction flow and the network throughput.
