Method for building enterprise scalability models from production data

1. A computer program product stored 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;

building a discrete event simulation model from the transaction cost, the transaction flow and the network throughput; and,

wherein the program step of calculating a resource consumption for the plurality of servers further comprises the program step of:

multiplying the resource utilization during a measurement period by the length of the measurement period to arrive at a resource consumption.

2. The computer program product of claim 1 wherein the program step of calculating a transaction cost from the resource data further comprises the program step of:

dividing the resource consumption by a number of transactions performed during the measurement period to arrive at a transaction cost.

3. The computer program product of claim 2 further comprising the further program step of:

deriving the transaction cost for each of the plurality of transactions related to the business function.
