Abstract: The disclosed embodiments provide a system for processing data. During operation, the system receives records of activity within a stream-processing system over a set of event streams, wherein each event stream in the set of event streams contains events related to a corresponding job in the stream-processing system. Next, the system indexes data in the records under a set of keys that include a first key related to jobs in the stream-processing system and a second key related to errors in the stream-processing system. The system then outputs the indexed data for use in analyzing the execution of the stream-processing system.

Abstract: Examples disclosed herein relate to performing a security action based on a comparison of digital signatures. An intrusion detection mode is initiated by a baseboard management controller. A first digital signature of hardware devices is calculated during the activation of the intrusion detection mode. The first digital signature is stored. Upon detection of a trigger, a second digital signature is calculated for the current hardware devices. The digital signatures are compared. A security action is performed based on the comparison.

Abstract: In one embodiment, a device receives sensor data from a plurality of nodes in a computer network. The device uses the sensor data and a graph that represents a topology of the nodes in the network as input to a graph convolutional neural network. The device provides an output of the graph convolutional neural network as input to a convolutional long short-term memory recurrent neural network. The device detects an anomaly in the computer network by comparing a reconstruction error associated with an output of the convolutional long short-term memory recurrent neural network to a defined threshold. The device initiates a mitigation action in the computer network for the detected anomaly.

Abstract: Examples disclosed herein relate to performing an action based on a pre-boot measurement of a firmware image. In an example, at a firmware component in a system, a measurement of a firmware image may be determined prior to booting of the system, beginning from a hardware root of trust boot block, by a Trusted Platform Module (TPM) emulator engine that emulates a hardware-based TPM. A pre-determined measurement of the firmware image may be retrieved from a storage location within the system. The measurement of the firmware image may be compared with the pre-determined measurement of the firmware image prior to booting of the system. In response to a determination that the measurement of the firmware image is different from the pre-determined measurement of the firmware image, performing an action.

Abstract: A power supply system for a lighting unit, comprises a driver, a local energy storage device and a converter. The converter implements a first, charging mode, mode by connecting to the output of said driver for diverting at least a part of the driving current from the lighting unit to charge the energy storage device, a second, battery driving, mode by connecting to the lighting unit for converting the local energy storage device power supply to drive the lighting unit, and a third, grid driving, mode to neither charge the energy storage device nor convert the secondary power supply. The converter and the driver are controlled actively and synchronously to maintain the current through the lighting unit when switching the converter between modes.

Abstract: Predicting data throughput with a user device comprises a wireless system supported by wireless access points receiving signals from the user device. A wireless prediction system receives data from the wireless system, where the data comprises characteristics of the wireless access point, characteristics of communications with user computing devices, and data throughput statistics. The prediction system categorizes the received data based on one or more of a set of characteristics and determines a maximum data throughput capacity for each of the one or more wireless access points for each of the one or more set of characteristics. The system receives a request for a prediction of data throughput capacity for a particular wireless access point and, based on the characteristics of the particular wireless access point, determines an estimated data throughput capacity based on data throughputs of wireless access points having similar characteristics.

Abstract: A network monitor may receive network log events and identify: a first set of network devices that have reported a target network log event, a second set of network devices that have not reported the target network log event, a first set of network log events reported by the first set of network devices, and a second set of network log events reported by the second set of network devices. The network monitor may determine which network log events are legitimate, and filter the legitimate network log events from the first set of network log events or the second set of network log events to produce a group of suspicious network log events that may be correlated with the target network log event. The network monitor may predict future suspicious network log events that may be correlated with the target network log event in order to predict equipment failures.

Abstract: Techniques for on-demand remote diagnostics for hardware component/device failure and disk drive data recovery using embedded media are described. In one example embodiment, a hardware device failure event alert along with a unique ID and a hardware device configuration fingerprint is sent upon detecting a hardware component failure event associated with the hardware device in a datacenter to an image management framework. A recovery image associated with the hardware device failure event is then obtained using the unique ID and the hardware device configuration fingerprint. The recovery image is then stored in an embedded storage media associated with the failed hardware device. The embedded storage media is then configured as a bootable hardware device. The hardware component failure is then diagnosed using the stored recovery image and the bootable hardware device upon hardware device boot-up. Recovering from the hardware device failure based on diagnosing the hardware component failure.
