Abstract: A method for cooperative active-standby failover between service routers based on health of services configured on the service routers is presented. In an embodiment, a method comprises determining, by a first service router (“SR”) of a SR cluster, a plurality of aggregate score values for a plurality of SRs of the SR clusters. The SR cluster comprises the first SR which is active, and a second SR. An aggregate score value, of the plurality of aggregate score values, indicates health of one or more services configured on a SR. The method further comprises determining, based on the plurality of aggregate score values, whether the first SR, of the SR cluster, is healthier than the second SR. In response to determining that the first SR is healthier than the second SR, the first SR continues to operate in the active mode; otherwise, the first SR switches to a standby mode.

Abstract: Automated methods and systems described directed to determining a root cause of problem with a system executing in a distributed computing system. Methods and systems train a normal-state model that characterizes a normal state of the system based on normal log files generated by event sources of the system executed under normal or test conditions. Methods and systems use the normal-state model and a log file containing log messages recorded about the time when a problem with the system has been detected to identify log messages that describe a root cause of the problem.

Abstract: A computer-implemented method of receiving and incrementally processing hierarchical data in a computing environment. Receiving hierarchical data within a computing environment. The computing environment including a plurality of interrelated components. Incrementally processing the hierarchical data to obtain processed portions. The incremental processing of the portions of hierarchical data able to be initiated with requiring receipt of the entirety of the hierarchical data. Maintaining an indexed representation of previously processed portions of the hierarchical data to prevent unnecessarily processing a same portion of the hierarchical data.
