An analysis system determines a system aspect of a system, determines an evaluation perspective for use in performing an asset management evaluation on the system aspect relating to a build of the system, an evaluation viewpoint corresponding to discovered information of the system and selects a plurality of data structures identifying data to be collected based thereupon. The analysis system, based upon the system aspect, the evaluation perspective, the evaluation viewpoint, and the plurality of data structures, determining context data. Based upon the plurality of data structures, the analysis system identifies a plurality of physical assets of the system for collection of data, queries the plurality of physical assets of the system to collect data to populate the plurality of data structures. The analysis system evaluates the data structures using the context data to produce an evaluation of at least some of the plurality of physical assets of the system.

Techniques are disclosed for dynamic access and instrumentation of model specific registers (MSRs). A virtual machine monitor (VMM) can provide a kernel application program interface (API) that can be utilized to access and instrument an MSR. A method may include receiving, by the VMM, an MSR instrumentation command that identifies an MSR to instrument and causing instrumentation of the MSR identified in the MSR instrumentation command. Instrumentation of the identified MSR can be caused by configuring or manipulating a virtual machine control structure (VMCS) of a guest virtual machine (VM). The MSR instrumentation command may be an MSR instrumentation request command, an MSR remove request command, an MSR value set request command, or an MSR value fetch request command. In some cases, the VMM may be a Type-I hypervisor.

A database node selects one of a number of database mirror hosts to perform a database read query. In theory, mirror hosts store redundant database entries. In practice, some mirror hosts fail to receive or retain some entries, e.g. if a mirror host was down for maintenance, a mirror host was overburdened, etc. The health of a mirror host, quantified as a health score, represents a likelihood that an insert statement was received and retained. Health scores are generated based on health metrics—data periodically retrieved from mirror hosts used to infer how well the database was operating, e.g. a count of entries that were inserted, a count of errors encountered while the entries were inserted, etc. If the database read query specifies entries inserted during a specific time period, the mirror host may be selected based on the health scores representing that time period.

A software placement device of a software placement system includes an information acquiring unit configured to acquire a finally-found location and a finally-found time, a deployment destination determining unit configured to calculate a data presence probability indicating a probability of a search target being detected at a certain time using the finally-found location and the finally-found time, to calculate a total cost using the data presence probability calculated and a computational cost and a network cost of each of base computers, and to select a base computer and a time interval for which the calculated total cost is a minimum, and a software distributing unit configured to distribute software to the selected base computer and transmit an analysis instruction for data of the selected time interval to the selected base computer.

Various implementations described herein are directed to technologies for providing error detection for a disk drive of a digital video recorder (DVR). Access data is measured according to a degree of usage of a disk drive of a DVR. The access data is stored. The stored access data is analyzed to detect performance degradation of the disk drive.

A method for monitoring multiple servers in one or more server clusters includes collecting and recording sensor data (SDR data) and storing the SDR as a predetermined file format into a specified storage area. The SDR stored in the specified storage area is analyzed according to a predetermined analysis rule to determine whether the SDR comprises data indicating abnormal functioning on a moment-by-moment basis SDR. When the SDR indicates an abnormality, SDR warning information corresponding to the abnormality SDR is outputted. A server monitoring device utilizing the method and a non-transitory storage medium are also provided.

Computer systems and associated methods are disclosed to implement a model development environment (MDE) that allows a team of users to perform iterative model experiments to develop machine learning (ML) media models. In embodiments, the MDE implements a media data management interface that allows users to annotate and manage training data for models. In embodiments, the MDE implements a model experimentation interface that allows users to configure and run model experiments, which include a training run and a test run of a model. In embodiments, the MDE implements a model diagnosis interface that displays the model's performance metrics and allows users to visually inspect media samples that were used during the model experiment to determine corrective actions to improve model performance for later iterations of experiments. In embodiments, the MDE allows different types of users to collaborate on a series of model experiments to build an optimal media model.

The adapter can be coupled to a vROPS API of the cloud infrastructure environment and arranged to issue requests for data to the network via the vROPS API. The adapter can include a means for issuing multiple initial requests. The adapter can include a means for receiving initial responses to the multiple initial requests. The adapter can include a means for issuing multiple subsequent requests in response to each initial response. The adapter can include a means for receiving subsequent responses to the subsequent requests. The adapter can include a means for processing the subsequent responses related to each resource ID to provide events, metrics or topology information. The adapter can include a means for delivering the events, metrics or topology information to a user display system.

Monitoring activity of an application prior to deployment is disclosed. A plurality of messages destined for a first application are received. Each message of the plurality of messages is duplicated to create a corresponding plurality of duplicate messages. Each message of the plurality of messages is successively sent to the first application and each duplicate message to a second application. Based on behavior information that identifies behaviors of the first application and the second application, it is determined that a behavior of the second application differs from a behavior of the first application beyond an alert criterion. In response to determining that the behavior of the second application differs from the behavior of the first application beyond the alert criterion, a message is sent to a destination indicating that the behavior of the second application differs from the behavior of the first application, the message identifying the behavior that differs.

An apparatus comprises at least one processing device that includes a processor coupled to a memory. The processing device is configured to receive, by a trace filter system, a trace chunk from a trace buffer associated with a processor core in a processing device, where the trace buffer is comprised of a plurality of trace chunks, to filter, by the trace filter system, the trace chunk, and to store the filtered trace chunk in the trace buffer.
