摘要： The present invention relates to a method to output information about estimated quality of experiences (QoEs) on a terminal on which a plurality of applications can be executed, the method comprising: performing QoE estimation on a per-application basis, separately for each application of the plurality of applications; outputting, by the terminal and based on the QoE estimation, information about the estimated QoEs, wherein at least some applications of plurality of applications have different estimated QoEs due to differences between the at least some applications, and wherein the terminal outputs the information about the estimated QoEs prior to execution of their respective applications; recommending, by the terminal and based on the estimated QoE of an application of the plurality of applications, execution of the application with a relatively lower-quality output or with a relatively higher-quality output, wherein the recommendation is provided by the terminal to a user of the terminal, wherein the QoE estimation is performed by issuing a request for one or more video data to a cloud, receiving the one or more video data from the cloud, measuring at least one quality factor based on the received one or more video data, and estimating QoE based on a relationship between the measured at least one quality factor and a criterion, and wherein the criterion is set based on data of the user of the terminal.

摘要： Systems and methods are provided for collecting application performance data. The system (100) includes a server (110) for hosting a server-side application (120). An instrumentation module (130) is included on the server. The instrumentation module can selectively instrument functions (125) of the server-side application to obtain instrumented function operation data. The instrumentation module can also maintain an instrumented function call stack (190) for each application thread. A sampling module (140) is included on the server. The sampling module can sample application threads of the server-side application to obtain sampled function operation data. The sampling module can sample application threads based on at least one of an age of a timestamp obtained through instrumentation and a determination of which threads are executing server requests based on emptiness of the stack.

摘要： To estimate the relation between virtual machine performance and scheduling parameters which are set in a scheduler which allocates CPU time to a virtual machine, provided is a performance prediction device, comprising a measuring unit and an estimation unit. The measuring unit sets the scheduling parameters to sample values, operates a virtual computer system, and measures CPU allocation delay time from when the virtual machine requests an allocation of the CPU to when the CPU is allocated to the virtual machine and turnaround time (TAT) of the virtual machine. Based on the results of the measurements, the estimation unit generates an estimation formula with the scheduling parameters and the CPU allocation delay time as explanatory variables and an estimated TAT as the response variable.

摘要： Embodiments of graphics instruction instrumentor (“GII”) and a graphics profiler (“GP”) are described. The GII may facilitate profiling of execution of graphics instructions by one or more graphics processors. The GII may identify target graphics instructions for which execution profile information is desired. The GII may store instrumentation graphics instructions in a graphics instruction buffer. The instrumentation graphics instructions may facilitate the GP in collecting graphics profile information. For example, timestamp-storage instructions may be store timestamps before and after execution of the target graphics instructions. The GII also may store an interrupt-generation instruction to cause an interrupt to be sent to the GP so that the GP may begin collection of graphics profile data. The GII may store an event-wait instruction to pause the graphics processors until an event is received. Other embodiments may be described and claimed.

摘要： A computing resource monitoring service receives a request to store a measurement for a metric associated with a computing resource. The request includes the measurement itself and metadata for the measurement, which specifies attributes of the measurement. Based at least in part on the metadata, the computing resource monitoring service generates a fully qualified metric identifier and, using the identifier, selects a logical partition for placement of the measurement. From the logical partition, the computing resource monitoring service transmits the measurement to an aggregator sub-system comprising one or more in-memory datastores. The computing resource monitoring service stores the measurement in an in-memory datastore within the aggregator sub-system.

摘要： A method may include performing stack trace sampling to obtain a compiled list of transactions performed by a software application during a preconfigured timeframe, filtering the compiled list of transactions according to a set of filtering parameters to obtain a set of transactions instances that complies with the set of filtering parameters, and finding a set of non-instrumented methods within the set of transactions instances that complies with the set of filtering parameters. The set of non-instrumented methods may exceed a percentage threshold of a total transaction time of transactions that the set of non-instrumented methods are a part of and the percentage threshold may be user-configurable. The method may further include adding a set of instrumentation points into a points file, the set of instrumentation points associated with the set of non-instrumented methods.

摘要： This invention provides a technique capable of efficiently performing debugging in a program and checking of soundness in a control system including a controller and a database system. A CPU unit (104) has a communication interface for connection to a database device (400). The CPU unit (104) executes a user program (186) to call a DB connection service in accordance with an instruction included in the user program and generate a statement to access the database device (400). In the DB connection service, a statement according to an access instruction is generated, and the generated statement is transmitted to a database system. After that, information indicative of time until a response from the database system is received is acquired, and the acquired information is stored as a log into a memory. A support device (300) acquires the information and displays it on a monitor.

摘要： Evaluating user experience for an application includes collecting, for each of a plurality of user sessions, a list of user event data items experienced from a perspective of a user device during that user session. For each user session, a session score is discerned based on an analysis of that user session's list of user event data items. Each session score is associated with a corresponding one of the plurality of users. For each of a plurality of successive time periods, user scores are discerned for each of the plurality of users. Each user score is discerned as a function of all session scores associated with that user where those session scores are for user sessions occurring during that time period. For each of the successive time periods, a period score is discerned as a function of the user scores discerned for that time period. The time period score discerned for a selected one of the successive time periods can be reported.
