Abstract: The technology disclosed relates to discovering multiple previously unknown and undetected technical problems in fault tolerance and data recovery mechanisms of modem stream processing systems. In addition, it relates to providing technical solutions to these previously unknown and undetected problems. In particular, the technology disclosed relates to discovering the problem of modification of batch size of a given batch during its replay after a processing failure. This problem results in over-count when the input during replay is not a superset of the input fed at the original play. Further, the technology disclosed discovers the problem of inaccurate counter updates in replay schemes of modem stream processing systems when one or more keys disappear between a batch's first play and its replay. This problem is exacerbated when data in batches is merged or mapped with data from an external data store.

Abstract: A self-healing system configured to automatically restore non-responsive or failed applications to a normal operating state. A self-healing system may restart an application after confirming that the application itself has failed—and not an underlying dependency failure. The self-healing system may also evaluate a server hosting an application reported as being non-responsive to determine whether that server has itself failed. If an application is non-responsive or has failed on an otherwise healthy host, and the dependent service use by the application are available, the self-healing system automatically restores the application to a responsive state. To do so, the self-healing system may generate a run list specifying a sequence of scripts invoked to restore the application to the responsive state.

Abstract: Systems, apparatuses, and/or methods may manage a fault condition in a computer system. An apparatus may dynamically publish a message over a publisher-subscriber system and dynamically subscribe to a message over the publisher-subscriber system, wherein at least one message may be used to address a fault condition in the computing system. The apparatus may predict a fault condition in a high performance computing (HPC) system, communicate fault information to a user, monitor health of the HPC system, respond to the fault condition in the HPC system, recover from the fault condition in the HPC system, maintain a rule for a fault management component, and/or communicate the fault information over the publisher-subscriber system in real-time. Messages may also be aggregated to minimize fault information traffic. The publisher-subscriber system may facilitate dynamic and/or real-time coordinated, integrated (e.g., system-wide), and/or scalable fault management.

Abstract: By monitoring requests to and from components of an application, an application analysis engine generates an inter-component graph for an application that identifies how the various components in the application are connected. When a performance issue is detected in association with the application, a traversal module traverses the inter-component graph to determine the possible execution paths that may have been the cause of the detected issue. The traversal module transmits requests to the correlation module to compare the metrics time series of the different components in the execution path with the detected issue. The correlation module compares metrics time series with the issue metric to identify correlations between execution patterns. The results of the correlation may be presented in a report that visually identify the root cause of the detected issues.
