Abstract: Implementations of the present disclosure involve an apparatus and/or method for conducting an at-speed functional test on a silicon wafer of an integrated circuit. In one embodiment, the method includes utilizing a first clock signal during a first portion of the test and a second clock signal during a second portion. The clock signals are configured such that a first subset of the logic stages of the circuit are tested at-speed by the first portion and a second subset of the logic stages of the circuit are tested at-speed. Further, in one embodiment, the first subset and the second subset comprise all of the logic stages of the circuit design. Through the configuration of the clock signals, the tester may ensure that each stage of the circuit design is tested at-speed such that a more accurate at-speed test result may be obtained in a low current environment.

Abstract: An application performance management system is disclosed. Operational elements are dynamically discovered and extended when changes occur. Programmatic knowledge is captured. Particular instances of operational elements are recognized after changes have been made using a fingerprint/signature process. Metrics and metadata associated with a monitored operational element are sent in a compressed form to a backend for analysis. Metrics and metadata from multiple similar systems may be used to adjust/create expert rules to be used in the analysis of the state of an operational element. A 3-D user interface with both physical and logical representations may be used to display the results of the performance management system.

Abstract: Generating pseudorandom test items for software testing of an Application Under Test (AUT) is provided. In one example, a method comprises selecting an oracle of one or more oracles within a test provider directory structure, the oracle defining one or more logical paths each comprising one or more test conditions and an expected result. A pseudorandom test item having an initial state of empty is generated, and a logical path of the one or more logical paths is selected. The one or more test conditions of the logical path are translated into a constraint. Based on the constraint, a pseudorandom test input is generated and stored in the pseudorandom test item in association with the expected result corresponding to the logical path.

Abstract: Embodiments are directed to predicting the health of a computer node using health report data and to proactively handling failures in computer network nodes. In an embodiment, a computer system monitors various health indicators for multiple nodes in a computer network. The computer system accesses stored health indicators that provide a health history for the computer network nodes. The computer system then generates a health status based on the monitored health indicators and the health history. The generated health status indicates the likelihood that the node will be healthy within a specified future time period. The computer system then leverages the generated health status to handle current or predicted failures. The computer system also presents the generated health status to a user or other entity.

Abstract: The relative health of data storage drives may be determined based, at least in some aspects, on data access information and/or other drive operation information. In some examples, upon receiving the operation information from a computing device, a health level of a drive may be determined. The health level determination may be based at least in part on operating information received from a client entity. Additionally, a storage space allocation instruction or operation may be determined for execution. The allocation instruction or operation determined to be performed may be based at least in part on the determined health level.

Abstract: The technology disclosed enables the automatic definition of monitoring alerts for a web page across a plurality of variables such as server response time, server CPU load, network bandwidth utilization, response time from a measured client, network latency, server memory utilization, and the number of simultaneous sessions, amongst others. This is accomplished through the combination of load or resource loading and performance snapshots, where performance correlations allow for the alignment of operating variables. Performance data such as response time for the objects retrieved, number of hits per second, number of timeouts per sec, and errors per second can be recorded and reported. This allows for the automated ranking of tens of thousands of web pages, with an analysis of the web page assets that affect performance, and the automatic alignment of performance alerts by resource participation.
