Data collection is provided, in which one or more affected transactions related to one or more transaction exceptions are determined. Based on one or more features of the one or more affected transactions, one or more trace features are determined. Based on the one or more trace features, a data collection rule is generated. Data of a subsequent transaction complying with the data collection rule is collected.

Data collection in transaction problem diagnostic

Provided are systems, methods, and media for concurrency conflict testing for shared resources. An example method includes identifying shared resources that are to be accessed by an application. Generating a plurality of concurrency test scenarios based on the shared resources. Analyzing a plurality of concurrency test cases to detect which concurrency test cases include a reference to the shared resources. Executing a concurrency test scenario. Performing the following while or before the concurrency test scenario is executing, obtaining analyzed concurrency test cases associated with the concurrency test scenario which referenced the shared resources, obtaining application modules pertaining to the obtained concurrency test cases, generating concurrency application modules by adding breakpoints to the obtained application modules, executing the obtained concurrency test cases until all of the obtained concurrency test cases are latched at the breakpoints, and simultaneously resuming the execution of the obtained concurrency test cases.
