Claim 18:
19. A computational environment for diagnosing a problem in an application, the computational environment comprising:
an application having multiple resources, wherein a set of one or more real-time features is extracted from each of the multiple resources of the application during a time window during which the problem exists;
a diagnostic service commutatively coupled with the application, the diagnostic service having a local classifier corresponding to each of the multiple resources for which real-time features are extracted, the local classifiers to generate a likely cause for each set of one or more real-time features, the diagnostic service providing a voting mechanism to select one of the likely causes from the local classifiers as an overall likely cause of the problem, wherein at least one of the local classifiers is pre-trained based on multiple time windows each having one or more faults injected into the application and, for each of the multiple time windows, sample sets of features from each of multiple resources within the application are extracted from corresponding logs and labeled with corresponding time window information and used as training information.
