Techniques and solutions are described for training and using a classifier based on a machine learning model to analyze performance information to assist in correcting a software bug or performance issue. The performance information can be processed prior to submission to a trained classifier, such as to remove, modify, or format data. A classification result provided by the classifier can be compared with a database to determine whether a solution or target is associated with the classification result. User feedback can be used to provide more accurate suggestions of solutions or targets, as well as to improve the accuracy of the classifier.
