A method and apparatus that uses application errors as a predictive metric for overall measuring of applications functional health are disclosed. The automated system intercepts messages exchanged between inter-services of enterprise applications, analyzes the context of those messages, and automatically derives application errors embedded in the message. Thereafter, it is capable of showing deviations from expected behavior for the purposes of predicting failures of the monitored application. Furthermore, the invention displays the user's real-time actionable data generated using the application errors.

A mitigation enablement module for a computer that improves application reliability. When performing memory management operations, the mitigation enablement module and associated memory manager selectively use mitigations that are intended to prevent an application bug from cause an application error. The memory manager may selectively apply mitigations for each of one or more applications based on the likelihood that such mitigations are successful at preventing bugs from causing application errors. The likelihood is determined from historical information on whether the mitigations, when applied, prevented bugs from causing memory operations that could cause application errors. This historical information can be gathered on a single computer over multiple invocations of the application or may be aggregated from multiple computers, each invoking the application. The determined likelihood may then be used to determine whether or for how long to apply the mitigation actions for memory operations requested by the application.

Mechanisms and techniques allow a data storage system to detect errors in data received for storage within the data storage system. To do so, the data storage system receives, from an originator application operating on a server computer system, portions of data which comprise an application data block which is to be written to storage in the data storage system. In conjunction with the data received at the data storage system, the data storage system also receives application error checking information which the originator application generates on the data within the application data block. The application error checking information may be, for example, checksum information embedded within one or more portions of the data which comprise the application data block. Upon receipt of the data and the application error checking information, the data storage system generates data storage error checking information on the data within all portions of data which comprise the application data block. The data storage system then compares the data storage error checking information against the application error checking information extracted from the portions of data to determine if an error exists in the data prior to storing a data in the data storage system. If an error exists, the data storage system can signal the error back to the server computer system. In this manner, the data storage system can detect errors in real-time in data that the originator application attempts to write to storage within the data storage system prior to storing the data.
