Transaction server performance monitoring using component performance data

A method for predicting transaction server performance failure in a transaction processing environment, the method comprising:

• aggregating performance metrics of a transaction server mediating transactions with a backend database management system, the performance metrics comprising measured values relating to the performance of different components of the transaction server and measured for the different components of the transaction server when the transaction server is determined to be operating within requirements set forth in a service level agreement (SLA) for the transaction server, the performance metrics comprising a running average of time during which a transaction remains pending in the transaction server in association with a corresponding one of the different components;
• utilizing the aggregated performance metrics to determine a benchmark of performance for mediating the transactions with the backend database management system for each of the components of the transaction server by maintaining timestamps according to a clock of each of the transactions as each of the transactions enter logic of a corresponding one of the components of the transaction server and are completed by the corresponding one of the components of the transaction server so as to determine a total time during which each of the transactions is pending in the transaction server in association with a corresponding one of the components;
• receiving after the aggregation and determination of the benchmark, a performance metric for the transaction server during nominal operation of the transaction server in memory of a computing system when the transaction server is determined to be operating within the requirements set forth in the SLA for the transaction server;
• comparing the received performance metric to the benchmark;
• and,
• responsive to the received performance metric falling outside a threshold variance from the benchmark, generating an alert of a potential impending failure of the transaction server, selecting a configuration parameter for a component of the transaction server corresponding to the received performance metric, locating in a table of parameters and adjustment values, a specified adjustment value for the selected configuration parameter, and adjusting the selected configuration parameter by the specified adjustment value so as to avoid the transaction server operating outside of the requirements of the SLA.
