sprint metrics

number of vehicles on the highway, the response time is the speed. When vehicles are scarce. When vehicles are very small, the speed is very fast, but the high rate of receipt is correspondingly low; with the increase of the number of highway trucks, the speed is slightly affected, but the high-speed fee received increases rapidly, and as the vehicle continues to increase, the speed becomes more and more slow, and the expressway is getting more and more fast. If the flow of traffic continues to

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

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

The two week of the second sprint officially ended today, with half of the 4 sprint plans in the past.Overall, Sprint 2 plans to complete 4 of the user story and actually completes 3 of them: Save ASC Art in server and generate ASC Art Gallery Generate dynamic ASC art from GIF Generate ASC Art based on WX ' s default sticker User Story 1 not

Before we introduce the disk I/O monitoring commands, we need to understand the metrics for disk I/O performance monitoring, and the performance of some aspects of the disk revealed by each indicator. Indicators for disk I/O performance monitoring mainly include:Indicator 1: Number of I/Os per second (IOPS or TPS)For disks, the continuous read or continuous write of a disk is called a disk I/O, and the IOPS of the disk is the sum of the number of cons

Elasticsearch is an open-source framework that provides search and correlation sequencing, while also supporting complex statistical-aggregation of stored documents. The Kubana icons are drawn based on aggregations. For more information, please refer to the Elasticsearch+logstash+kibana tutorial ObjectiveThe aggregations in ES are divided into two main categories: the metrics metric and the bucket bucket, and the

Before introducing the disk I/O monitoring command, we need to understand the disk I/O performance monitoring metrics, as well as the disk performance of each indicator. Disk I/O performance metrics include:Metric 1: I/O per second (iops or TPS)For a disk, the continuous read or write operation of a disk is called a disk I/O. The iops of the disk is the sum of the number of consecutive read operations and w

Enterprise Manager to perform an action when an indicator reaches the baseline of the measure or exceeds the number. Therefore, the management of metrics baselines is critical to the self-monitoring capabilities of the database system. If this metric baseline is set high, then the monitoring will not work. The database may have crashed when the system was alerted. If this metric baseline is set relatively low, then the database is frequently reported

topic: "What have we done in this sprint?" What's the next plan? " Sprint Summary: In this sprint, this is the first time members of our team started a team project development in the form of a team, as early as the first team meeting, we had a long time because of the problem of the team topic, after 2 discussions to finalize our current topic-the invit

A product backlog is a list of tasks that are broken down according to the initial requirements, including all functionality that is functional and non-functional, prioritized by the product owner for the task in the product backlog, and when the development team starts a task, the task is precisely defined and decomposed.The product backlog is the master of all the features that a product needs to have. When a project is just beginning, no one can foresee all the tasks and requirements beforeha

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
