I think the agile community needs to change the way it evaluates the success of agile teams. The way we collect metrics and get information from these metrics actually hinders us from making the software we use, and that's the most important thing. Pushing individual metrics sometimes leads to focusing too much on others and on team collaboration. This distorts

Label:Original: SQL Server Automation Operations series-Monitoring Performance metrics script (Power Shell)Requirements DescriptionGenerally in the production environment, sometimes need to automatically detect the status of the indicator value, if there is an exception, need early warning, such as e-mail notification, this article is introduced if the power shell to achieve status value monitoringRange of monitoring valuesBased on experience, as a DB

Server monitoring?? In addition to deploying WebApp, you need to monitor the service's exception information and server performance metrics when building the server, and notify the administrator of any exceptions.?? The server was built using Linux+nginx-1.9.15+tomcat7+java.?? Write scripts to detect error logs and server performance metrics, and use cloud monitoring to upload alarms to cloud accounts once

First look at a diagram:Note: The right image is often used in our workWhat are the Web performance metrics we focus on?1. Page load timeThe time to load from the page to the page onload event firing. In general, the OnLoad trigger represents the CSS,JS directly from the HTML reference, and the picture resource is fully loaded.2. Full page load timeFull page load time refers to the time that the network activity is not available after 2 seconds, start

LoadRunner)User-defined performance metrics – custom performance metrics supported by LoadRunner, such as: Transaction Response time, Transaction Per Second Passed, Failed.One.%processor time:cpu Average utilization%user Time: User-state CPU average utilization% Privileged Time: Kernel mindset CPU Average utilizationProcessor Queue Length: Number of threads in the processor queueContext switches per Second

If all of the internal technical factors are left behind, we only look at the performance metrics of the application, so generally speaking, the performance of the program can be measured in the following ways. N Response Time: The time the system responds to user behavior or events. The shorter the response time, the better performance, so we should try to use asynchronous processing in the system design process, so that users can receive receipts as

gives it to the thread, the thread is processed and returned to the main process, which is the 2-time switch. You can also use the values of CSR, IR, and TPS in the formula to get the number of transitions that each thing causes. Therefore, to reduce the CSR, you must work on the switch caused by each TPS, only n this value down, the CSR can be reduced, ideally n=0, but in any case, if n >= 4, you should check. In addition to the online csr Additional information: These three

This two-part article series will demonstrate a visualization technique that helps extract information from the data that has business value, and this article is the first part of the series. You'll see how to use Scalable Vector Graphics (SVG) and open source D3 JavaScript libraries to create visual representations that can be viewed through the browser, conveying information through shapes and colors. I'll demonstrate these techniques with some examples of visual browsing

Recently I joined a new Java project and found that the relationship between packages and classes is not very clear and confusing. The results of the CAP and JDepend checks are poor. It seems that not all people have this sense, about code quality, about design, about dependencies between classes, etc. Post two papers on this: OO Design Quality Metrics An Analysis of Dependencies Http://www.objectmentor.com/resources/articles/oodmetrc.pdf Software

video quality metrics (VQM), and the latest proposed space PSNR (Spsnr) and Time PSNR (Tpsnr).The remainder of this article is organized as follows. In the second part, we describe the basis of the viewpoint synthesis technique. In the third and fourth part, we put forward the viewpoint synthesis algorithm and the evaluation criterion respectively. Part V, we show and evaluate the performance of the proposed algorithm. Part VI summarizes the article.

Often people ask your company website how many IP?? How much PV?? How much UV?? How much concurrency??I'm the only one with a face!!Let's take a look at the terminology mentioned above separately.IpIP, which refers to the number of independent IP, independent IP number refers to the total number of times when a computer accessing a website by a different IP addressThe number of independent IP is an important measure of website traffic, it is generally said that a day how many IPUsually the sam

Resource utilizationRefers to the use of different system resources, such as server CPU utilization, disk utilization, and so on. Resource utilization is the main basis for analyzing system performance Index and improving performance, so it is the focus of Web performance testing work.Resource utilization is mainly for Web server, operating system, database server, network and so on, which is the main reference for testing and analyzing bottleneck. In the Web performance test, it is more necessa

Level One (Entry level, programmer level): This is the most basic level, with a certain amount of time professional training staff can achieve. The metrics are: 1. Have the most basic logical thinking ability, can analyze simple problem solving steps. 2. Familiar with the requirements of the development of the language of the basic syntax, commonly used function library or class library. 3. Master the use of the compiler, understand the general projec

The generalization performance of the learner is evaluated. In the measure, we should have the evaluation criterion to measure the generalization ability of the model. Performance metrics reflect task requirements, and using different performance metrics often leads to different judgments when comparing the capabilities of different models, which means that the model is relatively good or bad, and that the
