摘要： A method for diagnosing system health with system event logs is provided. The method includes receiving a plurality of event logs and health indicator states from a system; transducing the plurality of event logs into numeric-based metrics of the system; and deriving, based on the transduced numeric-based metrics, at least one model of the system that correlates the plurality of event logs to the corresponding health indicator states.

摘要： A method of automated diagnosis of a distributed system having a plurality of computing systems hosting replicated applications thereon is provided. The method includes deriving at least one diagnosis model correlating first metrics relating to a first application instance on a first one of the plurality of computing systems to a state of a system health indicator of the first application instance; determining whether the at least one diagnosis model is sufficiently accurate based on a probability of a predicted system health state of the first application instance given the first metrics and an actual system health state of the first application instance; and upon the determining that the at least one diagnosis model is sufficiently accurate, transferring the at least one diagnosis model to a second one of the plurality of computing systems for diagnosis of a second application instance on the second computing system that is a replicate of the first application instance.

摘要： Generating an inverted index is disclosed. Semi-structured data from a plurality of sources is parsed to extract structure from at least a portion of the semi-structured data. The inverted index is generated using the extracted structure. The inverted index includes a location identifier and a data type identifier for one or more entries of the inverted index.
