Data collection in transaction problem diagnostic

A computer system comprising:

• a processor;
• and
• a memory coupled to the processor, the computer system configured to perform a method, the method comprising:
• determining, based on a transaction exception resulting from execution of a transaction, multiple affected transactions that are affected by the transaction exception, wherein a transaction is a unit of work performed within a system to satisfy a request, and wherein each affected transaction of the multiple affected transactions is affected by the transaction exception resulting from execution of the transaction;
• determining one or more features of the multiple affected transactions, wherein a feature of an affected transaction of the multiple affected transactions comprises a name of a data field in a data block corresponding to the affected transaction and a value of the data field;
• determining one or more trace features based on the one or more features determined for the multiple affected transactions, wherein the determining a trace feature of the one or more trace features comprises selecting, from the one or more features determined for the multiple affected transactions, a selected feature that is in common for the multiple affected transactions in that each affected transaction of the multiple affected transactions has the selected feature and that selected feature for each affected transaction has a same data field with a same name and a same value and that selected feature is different for one or more successful transactions that occur concurrently with the multiple affected transactions in that at least a value of the same data field is different for the one or more successful transactions, the one or more trace features being one or more selected features common to the multiple affected transactions, and wherein the determining the one or more trace features further comprises:
• determining the one or more successful transactions that occur concurrently with the multiple affected transactions;
• and
• determining at least one feature in common with the multiple affected transactions that is different from at least one corresponding feature of the one or more successful transactions to be included in the one or more trace features;
• generating a data collection rule based on the one or more trace features that are in common with the multiple affected transactions, the data collection rule including the one or more trace features that are in common with the multiple affected transactions;
• and
• collecting data of a subsequent transaction complying with the data collection rule.

A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to perform a method comprising:

• determining, based on a transaction exception resulting from execution of a transaction multiple affected transactions that are affected by the transaction exception, wherein a transaction is a unit of work performed within a system to satisfy a request, and wherein each affected transaction of the multiple affected transactions is affected by the transaction exception resulting from execution of the transaction;
• determining one or more features of the multiple affected transactions, wherein a feature of an affected transaction of the multiple affected transactions comprises a name of a data field in a data block corresponding to the affected transaction and a value of the data field;
• determining one or more trace features based on the one or more features determined for the multiple affected transactions, wherein the determining a trace feature of the one or more trace features comprises selecting, from the one or more features determined for the multiple affected transactions, a selected feature that is in common for the multiple affected transactions in that each affected transaction of the multiple affected transactions has the selected feature and that selected feature for each affected transaction has a same data field with a same name and a same value and that selected feature is different for one or more successful transactions that occur concurrently with the multiple affected transactions in that at least a value of the same data field is different for the one or more successful transactions, the one or more trace features being one or more selected features common to the multiple affected transactions, and wherein the determining the one or more trace features further comprises:
• determining the one or more successful transactions that occur concurrently with the multiple affected transactions;
• and
• determining at least one feature in common with the multiple affected transactions that is different from at least one corresponding feature of the one or more successful transactions to be included in the one or more trace features;
• generating a data collection rule based on the one or more trace features that are in common with the multiple affected transactions, the data collection rule including the one or more trace features that are in common with the multiple affected transactions;
• and
• collecting data of a subsequent transaction complying with the data collection rule.
