An apparatus and method of monitoring messages forwarded from a first application to a second application each filter messages to produce a designated set of messages. Analysis of the designated set often can determine the source of an application error. To that end, the apparatus and method each receive messages forwarded from the first application to the second application. Each received message then is filtered by a filtering function that identifies the designated set of messages. Each message in the designated set is identified by the filtering function to be in the designated set when it determines that such message is a preselected type of message. An error thus may be detected in at least one of the first application and the second application, and at least one message in the designated set responsively may be analyzed to determine the cause of the error.

To facilitate the creation of rules for screening application layer requests to a computer application, a sample space of application layer requests is grouped according to one or more grouping criteria. Each grouping criterion may be a feature of application layer requests such that each grouping contains application layer requests with a common feature. For example, which the application layer requests follow the hyper-text transport protocol (HTTP), a common feature for some groupings could be a common URI pathname extension. A rule set for an application may be used to expose errors in the application. Test requests are constructed each of which violates at least one of the rules. The test requests are passed to the application to see whether the application throws the expected exceptions.

A method and apparatus that uses application errors as a predictive metric for overall measuring of applications functional health are disclosed.

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.

A method and apparatus for providing feedback to a programmer of a web based application notifying the programmer of application errors encountered by an end user of the application. A user error table is created to log application errors when a user computer is running the web based application. The present invention searches the user error table to determine whether an application error has occurred and only those errors which occur for a first time are forwarded to a server responsible for collecting the programmer's e-mail. A server error table is created to log those error messages received by the server and only those error messages which are unique are forwarded to the programmer. The programmer does not receive duplicate error messages relating to the same error and can use the feedback provided by the present invention to correct the application in subsequent versions. Error messages are filtered at the user computer level and at the server level such that the programmer will receive error messages for a particular programming error only once. The programmer is not inundated with multiple error messages relating to the same error by multiple users. Most preferably, the present invention is a computer program product incorporating known source code containing the means for providing feedback to the programmer of application errors stored on a server accessible to users who can download the application onto their user computers.

An error reporting system within the operating system of a computer that provides error reporting and / or debugging for managed applications. The error reporting service supports a registration programming interface through which applications that use non-native or non-standard error reporting functions can register runtime exception modules. A similar interface may be provided for applications to register debuggers. In response to a failure, such as a crash or an application hang, the error reporting service can poll the registered components to ascertain whether any is adapted for use in conjunction with such a failure. If so, the appropriate registered components can be used to collect failure data and / or debug the failed application. In this way, the error reporting service, and an existing framework that supports aggregation of application error reports, can be customized, including to allow error reporting and debugging of non-native applications.

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.
