Abstract: A system, method, and computer-readable storage medium are provided to automatically detect a root cause for an error that occurred during execution of functionality in a system. When a request is executed, a log associated with the execution of the request may be stored at the storage. The log may include information associated with a component associated with the execution of the request. Logs related to the same type of request may be compared with the executed request. Specifically, information associated with a component of the executed request may be compared with information associated with a component of the identified stored requests. When information associated with a component of the executed request does not match information associated with a component of the identified stored requests, a root cause for an error is associated with the associated component of the executed request.

Abstract: Tracking health of component in a computer system is disclosed. A health score for software components is determined for each of a plurality of time periods. The computing system determines a problem software component whose health score indicates the unhealthy status at a certain point in time. The computing system determines a set of software components that are linked by dependency relationships to the problem software component. The computing system tracks events at which software components in the set have a health score that went from the healthy status to the unhealthy status. The computing system rolls back in time through the events to locate a software component in the set that was first in time to have its health score go from the healthy status to the unhealthy status.

Abstract: A technique for detecting patterns in the execution of an application. The technique identifies a sequence of methods which are invoked and obtains information regarding attributes of the methods. For example, attribute information such as a class hierarchy can be obtained from an instrumentation API. A data structure representing a hierarchy of the attributes can be created and compared to one or more reference data structures which describe patterns of interest. A decision can be made to provide instrumentation for the methods having the matching attributes. The decision can consider how frequently the pattern is detected and overhead costs of the instrumentation.
