Abstract: Techniques for parallel data collection and recovery for a failing virtual processing system are disclosed. According to aspects of the present disclosure, an example method includes: detecting that the virtual processing system experiences an irreparable error; saving, by each of a plurality of processors of the physical processing system, a corresponding context and data stored in an allocated portion of a memory of the physical processing system to a data store; selecting one of the plurality of processors as a recovery processor; initializing, by the recovery processor, a pre-determined reserved portion of the memory; initiating, by the recovery processor, a new instance of the virtual processing system on the reserved portion of the memory while each remaining processor of the plurality of processors continues the saving; and dynamically adding each remaining processor of the plurality of processors to the new instance of the virtual processing system.

Abstract: In one embodiment, a device in a network monitors one or more metrics regarding network traffic associated with a particular application. The device detects an application-centric anomaly based on the monitored one or more metrics. The device causes an anomaly mitigation action to be performed in the network, in response to detecting the application-centric anomaly.

Abstract: Examples disclosed herein relate, among other things, to a monitoring system. The monitoring system may include a report analyzer configured to receive a report from one of a plurality of devices and determine whether the report includes at least one masked value. If the report includes at least one masked value, the report analyzer may be configured to determine, based on a plurality of reports associated with the masked value, whether an unmasking condition is satisfied, and if the unmasking condition is satisfied, to mark the masked value for unmasking.

Abstract: A method by a log stream analysis computer includes identifying records of log streams within a log repository containing a defined term. The log streams are generated by respective software sources executed by the host nodes. Similarity values are determined to indicate similarity between content of the records containing the defined term. A term node is generated to contain a data structure that identifies the defined term and lists identities of the records and corresponding ones of the similarity values. Related log stream analysis computers are disclosed.

Abstract: A system for obtaining performance data for different performance events includes a first application monitoring performance of a second application executing on a computing system. The first application identifies the type of event to be measured with respect to the second application, issues a first system call identifying the type of event, receives an identifier corresponding to the event type, and causes the second application to begin execution. After the execution of the second application is completed, the first application issues a second system call including the identifier corresponding to the event type, and receives a value of a hardware counter corresponding to the event type from an operating system.

Abstract: An analysis device for analyzing an operation of a target system has a behavior model obtained by modeling the operation of the target system, a log in which an event occurring when the target system is operated is recorded in time series is inputted to the analysis device, and the analysis device searches for an event string according to occurrence order obtained by statically analyzing the behavior model, from a plurality of events recorded in the log in time series. In the case where the target system includes a plurality of subsystems, the behavior model includes a plurality of behavior scenarios representing respective behaviors of the subsystems and a configuration model representing connection relation between the subsystems, and in each behavior scenario, a task executed by a corresponding subsystem and an event generated by the task are described.
