Microsoft Dynamics® AXTracing Dynamics AX 2009 Role Center KPI’sSummary: This document explains how to trace the data displayed in a Role Center page KPI to its source in the Microsoft Dynamics AX online transaction processing (OLTP) database.Author:Catherine McDade, Support Escalation EngineerDate Published: January, 2010Table of ContentsIntroduction (3)Terminology (4)KPI walkthrough (9)Description of KPI example (9)Step-by-step (9)Appendix A: Useful links (31)IntroductionThe prominent place of key performance indicators (KPIs) in Microsoft Dynamics AX 2009 Role Center pages has prompted questions about where the KPI data is drawn from. This document explains how to trace the data displayed in a KPI to its source in the Microsoft Dynamics AX online transaction processing (OLTP) database.Microsoft Dynamics AX relies on SQL Server Analysis Services (SSAS) for its business intelligence processing. In the following sections, we define terms of importance for SSAS, and then provide an example of how to trace the data for a KPI on a Role Center page.TerminologyKey Performance Indicator (KPI)A Key Performance Indicator is a measurement for gauging business success, or, in other words, ameasure of business metrics against targets. For example, a Sales Amount KPI could show sales from the last quarter and display a green icon if you are at budget, yellow if you are within 5% of budget, and red if you are under 5% of budget.Online Analytical Processing (OLAP)OLAP systems (such as that supported by SSAS) aggregate and store data at various levels across various categories.FactsFacts are predominantly numeric measurements, such as price or quantity, and represent the key business metrics that you want to aggregate and analyze. Facts form the basis of calculations, and you often aggregate them for members of a dimension.DimensionsDimensions form the contexts for the facts, and define the aspects of a business by which the facts are aggregated. For example, Items could be a dimension, while Price and Quantity could be facts of that dimension.Data sourceA data source stores the connection information for an SSAS project and/or database. WithMicrosoft Dynamics AX, the project or OLAP database that you create has a data source that points to your Microsoft Dynamics AX OLTP database.Data source viewA data source view contains the logical model of the schema used by an SSAS database object.Data source views can filter, apply calculations, and create joins on objects in the data source. In the OLAP database that Microsoft Dynamics AX creates, most of the data source views are simply views of a specific table, though some views may include a SQL statement that contains filters, calculations, or joins.MeasuresA measure represents a column that contains quantifiable data, usually numeric, that can beaggregated. A measure is generally mapped to a column in a fact table. An example of a measure would be Sales Amount or Cost of Goods Sold (COGS).CubeCubes store summarized fact and dimension data in structures that are multidimensional (that is, containing more than the two dimensions found in spreadsheets and normal database tables).Dimensions define the structure of the cube, and measures provide the numeric values of interest to an end user.Microsoft Dynamics AX 2009 ships with the following 10 default cubes:∙Accounts Receivable∙Human Resources Management∙General Ledger∙Production∙Project Accounting∙Purchase∙Sales∙Customer Relationship Management∙Expense Management∙Accounts payableMultidimensional Expressions (MDX)MDX is a query language, analogous to Structured Query Language (SQL), that is used to retrieve multidimensional data from a cube.Business Intelligence Development Studio (BIDS)An integrated development environment (IDE) based on Microsoft Visual Studio 2005 or 2008 and used to create and modify business intelligence solutions. This is the tool that you use to view and/or modify your Dynamics AX OLAP project or database.ProjectIn BIDS, a project is a collection of objects that make up your OLAP database. BIDS stores the objects (cubes, dimensions, etc) as files in the file system. It is recommended that you create a project for your OLAP database so that when you are making changes you are not affecting the database until you deploy.Below is a screen shot of BIDS opened to a project, followed by two screen shots that label the various sections of the BIDS environment.Detail view of BIDS, left side:Detail view of BIDS, right side:KPI walkthroughDescription of KPI exampleThis section walks you through an example of how to determine the origin of KPI values. We will use screen shots as needed to illustrate procedures.Scenario: Your CEO views her Role Center and wants to know where the numbers for the Production Cost KPI are coming from.Step-by-step1.In the Microsoft Dynamics AX client, go to the User profiles form (Administration >Setup > User profiles). On the form find and select CEO in the Profile ID column andthen click the View Role Center button.2. For the Production KPIs click the Manage KPIs link.3. Click the edit button on Production cost (the pencil icon). It will tell you that this ispulling from the Production Cube and the Production Cost KPI.4. To look at the KPI open SQL Server Business Intelligence Development Studio (BIDS). Ifyou are running SQL Server 2005, BIDS can be found at Start > All Programs >Microsoft SQL Server 2005 > SQL Server Business Intelligence DevelopmentStudio. If you are running SQL Server 2008, BIDS can be found at Start > All Programs > Microsoft SQL Server 2008 > SQL Server Business Intelligence Development Studio.5. Open your OLAP database (File > Open > Analysis Services Database).6. On the Connect To Database form, select Connect to existing database. Enter thename of the SQL Server Analysis Services Server in the Server field. In the Database field, enter Dynamics AX.Note: By default your OLAP database is named Dynamics AX. If you have applied adifferent name, use that name for Dynamics AX in the step above.7. Open the Production cube in the Solution Explorer section of BIDS. Find ProductionCube, right-click, and select Open.8. Click the KPIs tab.9. In the KPI Organizer, click the Production Cost KPI to open its setup form.10. The Value Expression section tells you what data the KPI is displaying.For this KPI we see that it displays the following:[Measures].[Actual vs. Planned Consumption]“M easures” could be a calculated measure or a measure on the cube structure. It istypically a calculated measure, so click the Calculations tab for the Production cube. 11. On the Calculations tab, find the Script Organizer and click the Actual vs. PlannedConsumption calculation.12.You will see in the Expression section it is doing the following:IF(ISEMPTY([Measures].[Cost of Planned Consumption]) OR [Measures].[Cost of Planned Consumption] = 0,NULL,([Measures].[Cost of Actual Consumption] / [Measures].[Cost of PlannedConsumption]) * 100)13. If we break the above statement down we see that the first part is:[Measures].[Cost of Planned Consumption] OR [Measures].[Cost of Planned Consumption] = 0, NULLWhat this tells us is that if these values return zero we will report null, otherwise we will do the calculation on the next line. First we need to find out if the above statement would return a zero, as shown in the following steps.14.Begin with the first part of the MDX query, [Measures].[Cost of PlannedConsumption]. On the Calculations tab you should see that Cost of PlannedConsumption breaks down to the following:[Measures].[Planned Cost Amount] + [Measures].[Planned Cost Markup]15. The Planned Cost Amount is another calculated measure that does the following:([Measures].[Cost amount], [Production Level].[Level].&[1])16.Cost amount is not a calculated measure, so we go back to the Cube Structure tab andin the Measures pane find CostCalcuation > Cost amount.17. Right-click Cost amount and select Properties.18. Expand Source, then expand Source again. The TableID is PRODCALCTRANS and theColumnID is COSTAMOUNT.19. To verify where the data is pulled from, go to the Solution Explorer and right-clickDynamics AX under Data Source Views. Select Open.20. On the Dynamics AX data source view tab, find PRODCALCTRANS under Tables.21. Right-click PRODCALCTRANS and select Edit Named Query.22.If you didn’t have an Edit Named Query option, it would mean the data was being pulledthe PRODCALCTRANS table using the following select statement:select costamount from prodcalctransHowever, since this is a named query, we need to find where the COSTAMOUNT column is coming from. To do this, look through the column labeled Column, find COSTAMOUNT, and then look at the Table column to see the source table.23.We see that the COSTAMOUNT column is pulling data from the PRODCALCTRANS table.The SQL statement would be:select costamount from prodcalctrans24.Now we need to trace the second part of the calculated measure, which is [ProductionLevel].[Level].&[1]. Find Production level in the Hierarchies tab underDimensions. Expand Production level and then click Edit Production Level.25.The Production Level hierarchy should appear under Production Level. Right click Leveland select Properties.26.In the Properties window, expand NameColumn and then expand Source. The sourceTableID is PRODCALCTRANS_LEVEL and the ColumnID is COLLECTREFLEVEL.27.We now know the data source that OLAP is using, but we want to find out where data isbeing pulled from in the Microsoft Dynamics AX OLTP database. To do this we can open the Dynamics AX option under Data Source Views in Solution Explorer.28.Scroll to PRODCALCTRANS_LEVEL, right-click, and select Edit Named Query29.The SQL statement for this data source is:SELECT DISTINCT COLLECTREFLEVEL FROM PRODCALCTRANS30.We now have enough information to build a SQL statement that would reflect the OLAPquery we saw in step 24 ([Production Level].[Level].&[1]). Adding the level of “1”from the end of the statement yields the SQL statement:select * from prodcalctrans where collectreflevel=1bining SQL statements yields:select sum (costamount) from prodcalctrans where collectreflevel=132.Now return to the second part of the MDX query [Measures].[Planned Cost Markup]from step 14.On the Calculations tab, find Planned Cost Markup. We see that this calculated measure is defined by([Measures].[Cost Markup], [Production Level].[Level].&[1])33.On the Cube Structure tab, navigate to CostCalcuation and then to Cost Markup.34.Right-click and select Properties for Cost Markup.35.In the Properties window, expand Source and then Source again. The displayedTableID is PRODCALCTRANS and the ColumnID is COSTMARKUP.36.Return to the Data Source View and look at PRODCALCTRANS and the Cost Markupcolumn (as in steps 20 through 23). The SQL statement turns out to be:select costmarkup from prodcalctrans37.We already found the SQL for production level.level &1 in steps 24-30. Combiningthat with COSTMARKUP yields:select sum (costmarkup) from prodcalctrans where collectreflevel=138.Now you can take the sum of COSTAMOUNT and COSTMARKUP (using the results fromsteps 31 and 37) where collectionreflevel=1. If that value is zero, then the KPI is null.39.If the value is not zero, then we continue tracing the KPI using the second part of thestatement from step 12:[Measures].[Cost of Actual Consumption] / [Measures].[Cost of Planned Consumption]) * 10040.The Cost of Actual Consumption is a calculated measure that has the followingexpression:[Measures].[Realized Cost Amount] + [Measures].[Realized Cost Adjustment]41.In the first part of the statement, the Realized Cost Amount measure is:([Measures].[Actual cost amount], [Production Level].[Level].&[1])42.Now look up the Actual cost amount measure. To find this measure, go back to theCube Structure tab and find Actual cost amount under CostCalculation.43.If we look at the properties of Actual cost amount we find that the source TableID isPRODCALCTRANS and the ColumnID is REALCOSTAMOUNT.44.This gives us a SQL statement of:select realcostamount from prodcalctransIf we add the production level of 1 (which we already found in steps 24 to 30) the SQL statement for all of step 41 is:select sum (realcostamount) from prodcalctrans where collectreflevel=145.Go back to step 40 and look at the second part of the statement[Measures].[Realized Cost Adjustment]Realized Cost Adjustment is a calculated measure equivalent to:([Measures].[RealCostAdjustment], [Production Level].[Level].&[1])46.The source of RealCostAdjustment can be found by going back to the Cube Structuretab and finding RealCostAdjustment under CostCalculation.47.If we look at the properties of RealCostAdjustment, we find that the source TableID isPRODCALCTRANS and the ColumnID is REALCOSTADJUSTMENT. Adding the production level of 1, we would see a SQL statement such as:select sum(realcostadjustment) from prodcalctrans where collectreflevel=148.To derive Cost of Actual Consumption, we would add the results of steps 44 and 47.49.Next we trace the second part of the statement from step 39:[Measures].[Cost of Planned Consumption]This results in the expression:[Measures].[Planned Cost Amount] + [Measures].[Planned Cost Markup]50.[Measures].[Planned Cost Amount] is a calculated measure equivalent to:([Measures].[Cost amount], [Production Level].[Level].&[1])51.To find [Measures].[Cost amount], go back to the Cube Structure tab and find Costamount under CostCalculation.52.If we look at the properties of Cost amount, we find that the source TableID isPRODCALCTRANS and the ColumnID is COSTAMOUNT. Adding the production level of 1, we would see the SQL statement:select sum (costamount) from prodcalctrans where collectreflevel=153.Return to step 49 for the next part of the statement:[Measures].[Planned Cost Markup]This is a calculated measure equivalent to the expression:([Measures].[Cost Markup], [Production Level].[Level].&[1])54.To trace this measure, go back to the Cube Structure tab and find Cost Markup underCostCalculation.31 TRACING DYNAMICS AX 2009 ROLE CENTER KPI ’S55. If we look at the properties of Cost Markup , we find that the source TableID isPRODCALCTRANS and the ColumnID is COSTMARKUP. Adding the production level of 1,we see the SQL statement:select sum (costmarkup) from prodcalctrans where collectreflevel=156. The results for [Measures].[Cost of Planned Consumption] would be the sum of steps 52and 55.57. Therefore, the results for [Measures].[Cost of Actual Consumption] / [Measures].[Cost ofPlanned Consumption]) * 100 This means we have to divide the results from step 48 bythe results of step 56. Then we take that number and multiply it by 100 to get our actualvs. planned consumption which is what gives us the Production Cost KPI.After following these steps you should now know where the data that makes up the Production Cost figure on the KPI is coming from. You should also have learned how to trace a KPI so that you can determine where any KPI is pulling data from.Appendix A: Useful links∙ Microsoft Dynamics AX 2009 Business Intelligence Cube Reference Guide: /downloads/details.aspx?FamilyId=6A685DF3-912D-4545-B990-CD2283C159FB&displaylang=en∙ Role Center reference for Microsoft Dynamics AX: https:///dynamics/ax/using/ax_rolecenterreference.mspxReferences:∙The information above was taken from SQL Server books online.

performancetest工具结果解析-回复Performancetest工具结果解析Performance testing is a crucial aspect of software development as it provides insights into the performance and scalability of an application. Performance testing involves using various tools and techniques to evaluate system response time, throughput, and stability under different workloads. One such tool widely used for performance testing is Performancetest. In this article, we will delve into the interpretation and analysis of Performancetest tool results.1. Introduction to Performancetest:Performancetest is a comprehensive performance testing tool developed by PassMark Software. It allows testers to assess the performance of their applications by simulating real-world scenarios and generating detailed performance reports. This tool supports a wide array of performance tests, including CPU, disk, memory, 2D and 3D graphics, networking, and more.2. Understanding Performancetest metrics:Performancetest provides a range of metrics that help gauge the performance of an application. Some of the important metricsinclude:2.1 CPU performance:This metric measures the performance of the CPU by performing complex calculations and generating a score. A higher score indicates better CPU performance.2.2 Disk performance:Disk performance evaluates the read and write speeds of a storage device. It determines how quickly data can be accessed from or written to the disk. The metric reports the transfer rate in MB/s, with higher values indicating faster disk performance.2.3 Memory performance:Memory performance tests the speed at which the system can read from and write to the RAM. It measures the memory's latency and throughput. A higher score indicates better memory performance.2.4 2D and 3D graphics performance:This metric assesses the graphical rendering capability of the system. It performs rendering operations and provides a score. A higher score suggests better graphics performance.2.5 Networking performance:Networking performance tests the speed at which data can be transferred over a network connection. It measures the throughput and latency of the network. Higher values indicate better networking performance.3. Interpreting Performancetest results:Performancetest generates detailed reports in tabular and graphical formats, making it easier to interpret and analyze the results. Here's a step-by-step guide to interpreting the results:3.1 Identify the performance metrics being measured:The first step is to identify the metrics being measured in the performance test. Look for the specific metrics mentioned in the results report, such as CPU performance, disk performance, memory performance, and so on.3.2 Analyze the scores or values:Next, analyze the scores or values associated with each metric. Compare the values with industry benchmarks or previous test results to gauge the performance of the application. Higher scoresor values generally indicate better performance.3.3 Look for any anomalies:Check for any significant deviations or anomalies in the results. Anomalies may indicate performance bottlenecks or issues that need further investigation. For example, a sudden drop in network performance could suggest a network configuration problem.3.4 Consider the workload:Consider the workload used during the test and how it relates to the application's real-world usage. If the workload simulated in the test does not align with the expected usage pattern, the results may not accurately reflect the application's performance.3.5 Identify performance limitations:Identify any performance limitations based on the results. This could include CPU bottlenecks, slow disk read/write speeds, memory constraints, graphics rendering issues, or network latency.4. Understanding the implications of results:Interpreting Performancetest results also involves understanding the implications of the findings. Here are a few key considerations:4.1 Scalability:Evaluate how the application performs under different workloads. Determine if the performance remains consistent or degrades as the workload increases. Scalability issues could indicate the need for optimization or infrastructure upgrades.4.2 Performance bottlenecks:Identify the factors causing performance bottlenecks and prioritize their resolution based on impact. This could involve optimizing code, improving database queries, or upgrading hardware resources.4.3 Dependency analysis:Analyze dependencies between different components of the system and identify any bottlenecks or performance issues. For example, slow disk performance may impact overall application performance.4.4 Root cause analysis:If performance issues are identified, conduct a root cause analysis to determine the underlying reasons. This could involve analyzinglogs, profiling the application, or using additional diagnostic tools.In conclusion, Performancetest is a powerful tool for evaluating the performance of software applications. Understanding and interpreting the results generated by this tool is crucial for identifying performance bottlenecks and optimizing the application. By following a systematic approach and considering various factors, testers can gain valuable insights from Performancetest results and enhance the overall performance of their applications.。

One day she had an idea for a dish machine that worked without using water. She went to see several dish washer manufacturers about producing the machine. But none of them were interested. Joanna found investors to support her idea and founded her own production company. She spent millions of dollars on developing her dish washer. And it was put to the market three years later. From then on, sales were very good, better even than Joanna had hopped. But Glob Domestic, one of the companies that she has been to see made its own waterless dish washer. Joanna obtained one and found they use the technical ideas she had developed. She had obtained legal protection for these ideas. So that other companies could not use them. After a long legal process, Glob Domestic was forced to stop ma king its competing dish washer and to pay Joanna several million dollars. Now Joanna’s waterless dish washer has 40℅of the worldwide dish washer market, and this is increasing every year.Question 31: How did the manufacturers fill Joanna’s idea for a dish washer?Question 32: How does the sales of the new dish washer goes?Question 33: Why was Glob Domestic forced to pay Joanna much money?Question 34: What is the market share of Joanna’s dish washer?Question 35: What is the story mainly about?Section Five:Now it’s eight o’clock, time for the morning news.Internet use continues to increase in the United States. According to a new study by American Life Project, fifty two percent of rural residents now have Internet access. That’s an increase of eleven percent since 2000. Rural residents are still behind the urban residents, however. Sixty seven percent of urban residents use the Internet. Of those rural residents who are online, forty five percent say that they surf the Web daily. Only forty percent of urban residents use the Web that often. One big barrier for rural residents is the lack of choice among Internet providers. According to another survey, more than two million American children aged six to seventeen have their ownpersonal websites. This figure, which represents ten percent of the twenty three million young people, who have Internet access from home, is rising rapidly. It is expected to jump to one in four kids by 2008. The survey also shows that boys are more likely than girls to have their own websites. Seventy six percent of kids with broad band Internet access at home say that their home connection is faster than the connection at school. Forty nine percent of kids say that they get too little time on line at school.Section Six:Private CarWith the increase in the general standard of living, some ordinary Chinese families begin to afford a car. Yet opinions of the development of a private car vary from person to person.It gives a much greater degree of comfort and mobility. The owner of a car is no longer forced to rely on public transport, and hence no irritation caused by waiting for buses or taxis. However, others strongly object to developing private cars. They maintain that as more and more cars are produced and run in the street, a large volume of poisonous gas will be given off, polluting the atmosphere and causing actual harm to the health of people.Whether private cars should be developed in Chicago is a difficult question to answer, yet the desire for the comfort and independence a private car can bring will not be eliminated.Part Two:Secton One:M:How do you like living in the campus apartments?W: Well…it’s OK. I mean, I like the apartment, but my roommate is kind of a problem. Sometimes she uses my things without asking—mostly little things,like paper and toothpaste, but once it was my favorite sweater. And she never cleans the bathroom when it’s her turn.M: Have you sat down with her and had a good talk about these things?W: Maybe if I saw her more oftem. The problem is ,she’s hardly ever home.M: Try leaving her a note.W: I did,but it didn’t help.M: Isn’t there an apartment manager, someone who will help you sort out problems like this? He maybe can set up a meeting with your roommate.W: I didn’t know the manager does that kind of thing. I guess I could find out.M: And if that doesn’t work…if talking it orver doesn’t help, then you should probably just move out, find another place. There’s always someone looking for a roommate.。

S.M.A.R.T-参数解析

S.M.A.R.T-参数解析

S.M。

A.R.T 参数解析S.M.A.R.T(Self Monitoring Analysis and Reporting Technology /自我监测、分析与报告技术)是为了提高硬盘数据的安全性而开发的。

它可以使硬盘实时检查自身的状态,通过一定机理及时分析出潜在的问题,报告给系统,有时甚至能给出预计的硬盘故障日期,实际就是一种预警技术。

这个功能可以比较客观的反映硬盘目前的健康状况。

提示:该硬盘没有任何损坏。

因为SATA数据线曾经被多次拔插过,造成SATA数据线接口处,金属弹簧触片磨损氧化、弹性下降引起的接触不良。

使(C7)值上升。

故障表现:电脑卡死、蓝屏、无法开机.甚至硬盘丢失(BIOS里也没有硬盘信息)运行一些程序时会弹出警告:(X:是运行程序所在分区)无法访问X:\.由于I/O设备错误,无法运行此项要求。

先判断是硬盘出现坏道了,但当把硬盘接到另一台电脑后,硬盘一切正常使用,说明硬盘没有问题。

后来换条SATA数据线,故障解决。

(C7)值也不再增加。

后来网上查看资料,SATA 数据线有弊端: 就是SATA 数据线拔插次数有限, 质量差的,拔插几次就没用了。

Value/Current(当前值) 当前硬盘该属性的值。

Worst (最坏值) 该属性出现过的峰值。

Threshold/Warn(阈值/临界/极限值)硬盘厂商所规定的该属性峰值.如果某个属性超过Threshold 规定的极限值时,就表示你的硬盘可能出现了问题. Raw Values/Data (Raw 值/数据) 。

和该属性有关联的数据总值。

怎么看这类属性?主要是看Raw 和Worst 的值是否还在临界值之内(>或<临界值)一般使用软件如HDTune 、CrystalDiskInfo 等,一般属性中有黄色或者红色你就要注意了,硬盘可能快坏了,要是还在保修期内,就赶紧备份数据,送去检修。

下面我们来介绍各个属性(按2010年2月11日 维基百科 上的解释)指从磁盘表面读取数据时发生的硬件读取错误的比率,Raw 值对于不同的厂商有着不同的体系,单纯看做1个十进制数字是没有任何意义的。
