Patent number: 11144556Abstract: Instead of processing a query as-is, the query is chunked or broken down into a sequence of smaller chunked queries and the chunked results of those smaller queries are streamed back to the requester. Chunking the query and streaming the chunked results can substantially decrease the user's time to value when running a query by returning some immediate results for display which are refined and eventually converge on the full results as each chunked query runs.Type: GrantFiled: April 29, 2016Date of Patent: October 12, 2021Assignee: Cisco Technology, Inc.Inventors: Eric Vandenberg, Arjun Iyer

Patent number: 10775751Abstract: In one aspect, a regular expression is automatically generated based on user input for fields that are desired to be extracted from log lines. The input may be received by user through an interface provided by a machine such as a controller. The input may identify one or more fields within a log line that should be extracted. Multiple instances of potential regular expression portions may be generated based on the user input, and different portions are combined together to determine if they achieve the desired extraction. Once a complete regular expression is generated based on user input, a user may provide additional input to identify examples or counterexamples of log line fields that satisfy or don't satisfy the user's intended extraction.Type: GrantFiled: January 29, 2016Date of Patent: September 15, 2020Assignee: Cisco Technology, Inc.Inventors: Yuchen Zhao, Nima Haddadkaveh, Arjun Iyer

Patent number: 10268750Abstract: Clusters of log lines are identified based on log line templates. The log line templates are based on a punctuality pattern for a log line. Clusters of log lines that match each punctuality pattern can be identified based on comparisons between the log lines. The comparison may determine the similarity of the log lines and ultimately identify whether the log lines are close enough to be clustered. The comparison may be based on generated n-grams for the log lines and performing a hash on the n-grams. The resulting cluster information may be communicated to a user in an interface.Type: GrantFiled: January 29, 2016Date of Patent: April 23, 2019Assignee: Cisco Technology, Inc.Inventors: Yuchen Zhao, Arjun Iyer

Patent number: 10210036Abstract: A system that utilizes a plurality of time series of metric data to more accurately detect anomalies and model and predict metric values. Streams of time series metric data are processed to generate a set of independent metrics. In some instances, the present system may automatically analyze thousands of real-time streams. Advanced machine learning and statistical techniques are used to automatically find anomalies and outliers from the independent metrics by learning latent and hidden patterns in the metrics. The trends of each metric may also be analyzed and the trends for each characteristic may be learned. The system can automatically detect latent and hidden patterns of metrics including weekly, daily, holiday and other application specific patterns. Anomaly detection is important to maintaining system health and predicted values are important for customers to monitor and make planning and decisions in a principled and quantitative way.Type: GrantFiled: April 20, 2016Date of Patent: February 19, 2019Assignee: Cisco Technology, Inc.Inventors: Arjun Iyer, Yuchen Zhao

Publication number: 20070244689Abstract: An embodiment of the present invention describes a method and system for using related data from external systems employing incompatible character sets to affect a business process. For one embodiment, a first external system uses a first character set. A first data set is received from the first external system, the first data set using the first character set. The first data set a subset of a second data set. A second external system uses a second character set. A third data set, which is also a subset of the second data set, is received from the second external system, the third data set using the second character set. The first data set and the third data set are converted to use a third character set, the third character set a superset of the first character set and the second character set. The first data set and the third data set are then used to effect one or more business processes. For one embodiment, the third character set is Unicode.Type: ApplicationFiled: June 20, 2002Publication date: October 18, 2007Inventors: Jon Degenhardt, Peter Thorson, Arjun Iyer

Publication number: 20070192336Abstract: A Structured Query Language (SQL) adapter business service that converts data from a data set to a common representation format used for all data sets with which the SQL adapter business service interacts. Hence the SQL adapter business service can communicate with various internal and external systems independently of the native format in which those systems maintain and store data. The SQL adapter business service optimizes operations to update data in the data sets by combining operations when possible and by using result sets from executing previous SQL statements to construct subsequent SQL statements. SQL adapter business service takes advantage of parent/child relationships between tables to construct SQL statements in an order such that the SQL statements process only a minimum amount of data, thereby making retrieval of data as efficient as possible.Type: ApplicationFiled: November 15, 2001Publication date: August 16, 2007Inventors: Arjun Iyer, Chandrakant Bhavsar
