  • Patent number: 10803083
    Abstract: A method generating a platform-agnostic abstract syntax tree (AST) comprises receiving data in a predefined format, through an input unit; subsequently parsing the data to extract model information corresponding to the predefined format of the data; and transforming, by a processing server, the model information to an abstract syntax tree (AST) structure. The above steps aid in generating, by the processing server, a platform-agnostic AST by combining predefined metadata and the abstract syntax tree (AST) structure.

  • Publication number: 20200204428
    Abstract: Automated fault correction in a network environment comprises identifying a pattern in a set of network events and generating a set of substantiating data for the identified patterns. The method can also identify an occurrence probability value for each network event and generate root cause data based on a ranking for the network events using a set of parameters including the occurrence probability. The method can also be directed to performing a regression of the root cause data against a set of historic data and selecting the root cause with a predefined accuracy as an acceptable candidate. The acceptable candidate is then provided for assisted learning for automated fault correction.

  • Patent number: 10592473
    Abstract: This technique improves energy efficiency of MapReduce system by using system performance model without changing any component of the MapReduce system. This involves determining presence of any hardware bottleneck in any node of MapReduce system based on a system performance model and if any hardware bottleneck is present in any node, then the maximum bandwidth value of hardware associated with the bottleneck of each node is determined. Thereafter, an energy efficient value of Central Processing Unit (CPU) frequency of each node having the bottleneck is determined by using the system performance model and the maximum bandwidth value of hardware associated with the bottleneck. Further, the CPU frequency of each node having the bottleneck is set at the energy efficient value determined in the earlier step.

  • Patent number: 10552511
    Abstract: The technique relates to a system and method for data-driven anomaly detection. This technique involves identifying region of interest from the data based on dimensionality reduction technique and change point detection algorithm. A reference data can be obtained separately or can be obtained from the test data also, wherein the reference data represent the normal operating condition of a system. The reference data are classified into different groups representing different modes of operation of the system. A control limit is determined for the different groups. The data within the region of interest are mapped with the different groups of the reference data and it is determined if the mapped data fall outside of the control limit of the mapped group. Finally, at least one abnormal event is detected by applying a heuristic algorithm on the data within the region of interest which are outside the control limit.

  • Patent number: 10439898
    Abstract: A computer implemented system and method for pro-active application monitoring and alerting using affinity band. To enable pro-active monitoring, the present invention may derive affinity band. The invention accesses performance data generated from monitoring an application associated with one or more transaction and configuring iteration period to derive affinity band. The method provides configuring an interval within iteration period whereby all performance metric values may be aggregated and deriving affinity band for each of the performance metrics. The affinity band may then be used as benchmark or threshold to monitor current values for each of the performance metrics. Alerts may be raised through pro-active monitoring mechanism when the current values of the performance metric go beyond the threshold set, displaying a tendency to rise or go beyond normal values with extent of deviation.

  • Patent number: 10416990
    Abstract: Methods, systems and non-transitory computer readable media involves receiving information of a new library from a patch management repository. A symbolic link to the new shared library is created and a request to an application process to replace a shared library is communicated. To replace the shared library, the application process periodically checks reference state of the shared library till it reaches a free-state. When the shared library reaches the free-state, the application process unloads the shared library from memory space and loads the new shared library to the memory space. The application process continues performing one or more pre-define functions during the replacement of the shared library.
