Abstract: A system and method for identifying computer system performance signatures and for identifying the cause of undesirable performance signatures, particularly with respect to both application-based and computer system-based parameters. Respective parametric information data is matched with corresponding parameters found in a stored plurality of reference signatures. If a match is found between the behavior of a computer system under study and a reference signature, the present invention provides information about the cause(s) of the reference signature, such that appropriate remedial measures can be taken. If a match is not found (according to predetermined matching rules), then the present invention may provide additional prompts to request additional information or test data such that the signature of computer system being tested can be further refined so that the signature of the target computer system might more closely match a reference signature.

Abstract: One embodiment of the present invention provides a system that facilitates measuring quality-of-service of a computer network server or collection of servers by determining the effect that transactions in one category of service have on transactions in other categories of service. The system operates by generating a varying pattern of synthetic transactions for one category of service and a fixed pattern of synthetic transactions for the other categories of service. The system sends the varying pattern and the fixed pattern of synthetic transactions and receives responses to these patterns across a network between the computer network servers and the synthetic transaction generator. The system measures the response time for the varying pattern of synthetic transactions and the response time for the fixed pattern of synthetic transactions. Additionally, the system calculates the effect of transactions in one category of service on response times in the other category of service.

Abstract: A tool is described herein for optimizing the design of a hardware-software system. The tool allows a designer to evaluate the potential improvement in system performance that may be realized by moving selected software components of the system to a hardware implementation. In one aspect, the tool automatically generates a performance profile of an original form of the system. The performance profile of the original form of the system may be used to select software components of the system to be moved to hardware. In another aspect, the tool generates an estimated performance profile of a repartitioned form of the system by modifying the performance profile of the system. The estimated performance profile of the repartitioned system is compared to the performance profile of the original form of the system to verify benefits, if any, of repartitioning. Such verification is accomplished without the need to actually repartitioning the system or measuring the performance of the entire repartitioned system.

Abstract: Conventionally, a web site stores Internet data indicating file access status for the files that have been accessed in response to requests from web browsers. Unfortunately, the Internet data are kept as a set of separate and non-correlated data records that are chronologically arranged according to the times at which the requests have been received and processed. Consequently, the Internet data are not arranged meaningful to management and business operation. The present invention is able to correlate web page files (HTML, SHTML, DHTML, or CGI files) with individual users. The present invention is also able to correlate web page files with user sessions during which users perform their business transactions over the Internet.

Abstract translation: 通常，网站存储指示响应于来自网络浏览器的请求而被访问的文件的文件访问状态的互联网数据。 不幸的是，互联网数据被保存为一组单独和不相关的数据记录，这些数据记录根据请求被接收和处理的时间按时间顺序排列。 因此，互联网数据并没有对管理和业务运作有意义。 本发明能够将网页文件（HTML，SHTML，DHTML或CGI文件）与各个用户相关联。 本发明还能够将网页文件与用户会话相关联，在该会话期间用户通过因特网执行其业务交易。

Abstract: A method of facilitating an outbound customer interaction involves monitoring user access activity, and automatically accumulating access data concerning such user access activity, with respect to a resource retrieved from one or more network locations (e.g., identified by URLs). The user access to the one or more network locations typically occurs via a user device coupled to a network to facilitate the access to the network locations. A trigger event is then detected based on the user access activity as reflected by the accumulated access data.

Abstract: A method for obtaining an estimate of response time for a typical transaction request in a computer system under varying load conditions. This estimate can be compared to a predefined value considered by the system administrator to be the level at which the response time becomes significantly degraded, thereby providing a measure of the operating condition of the computer system. Preliminary measurements include measurement of response time for the typical transaction request while the computer system is lightly loaded, CPU usage, and response times for more than one concurrent typical transaction request. During computer system operation only the number of concurrent transaction requests and the total CPU usage need to be obtained and measured. A primary advantage of the embodiments as described in the present patent document over prior methods is that the present methods can provide a more accurate approximation of actual response-time under varying loads while consuming less system resources to do so.

Abstract: One embodiment of the present invention provides a system that dynamically characterizes computer system performance. The system operates by simultaneously varying multiple input variables in the computer system, and gathering performance results by measuring time-dependent responses in one or more response variables. In this way, responses to variations in the multiple input variables can be measured simultaneously. Next, the system analyzes the performance results to determine correlations between input variables and output variables.

Abstract: Methods and systems that adaptively measure and collect performance data are disclosed. An exemplary method includes acquiring system performance data in accordance with a performance policy. Then, data measurement and collection is dynamically adjusted based on the performance policy and a detected system condition. An alternative method includes establishing a self-monitoring data collection policy. At least one system performance metric is then measured in accordance with the self-monitoring data collection policy. The at least one system performance metric is evaluated to determine system health. The system performance metric measuring step is then dynamically adjusted based on the self-monitoring data collection policy and the system health. The steps of measuring, evaluating and dynamically adjusting are then repeated.
