Method for building enterprise scalability models from load test and trace test data

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

• gathering resource data from a function load test on a plurality of servers deployed on a network;
• wherein the resource data includes a reporting interval, a plurality of timestamps, and a plurality of resource utilization indicators;
• 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 plurality of resource utilization indicators;
• gathering network data from a functional trace test;
• deriving a transaction summary from the network data;
• deriving web log data from the function load test;
• calculating a number of business functions from the transaction summary;
• calculating a resource consumption for the plurality of servers;
• deriving a business function profile from the resource data and the number of business functions;
• adopting a transaction flow from the transaction summary;
• and
• building a discrete event simulation model from the business function profile and the transaction flow.

A method of preparing an instruction table of a business function for a discrete event simulation modeler comprising the steps of:

• measuring network flow trace data on a network;
• analyzing the network flow trace data to derive a transaction summary;
• gathering resource data from a plurality of servers on the network;
• gathering web log data from at least one server on the network;
• calculating a number of business functions from the network flow trace data;
• calculating a resource consumption from the resource data;
• calculating a business function cost;
• creating a business function profile from the business function cost;
• and
• building an instruction table from the transaction summary and the business function profile.
