1. First inconsistency: The Controller runtime's real-time statistics are inconsistent with the statistical data in the analysis results file. cause Analysis:Controller real-time data statistics sampling frequency and analysis the default data statistics sampling frequency may be different (general controller is 5 seconds, analysis is 1 seconds), so the statistical data obtained by the two different statistical results are different;Workaround:The sampling frequency of the controller real-time data statistics is set consistent with the analysis default data sampling frequency;Operation guideline:Analysis> Select inconsistent chart items >view>set granularity> Set the same Controller;controller> select inconsistent chart items >Monitors> Online graphs>configuration> Set refresh rate consistent with analysis; Note: This problem may also be caused by inconsistent sampling time periods of data samples, set the controller's graph to whole by referring to the above method Scenario the statistics of the controller's real-time data statistics are based on the data collected from the whole scene, and whether the filter setting containing the think is likely to cause the problem. 2. Second inconsistency: When analysis views the result file, the average Transaction Response time statistics for reports summary peport and graphs are inconsistent. cause Analysis:The two calculations based on the data sample space are different,reports Summary Peport statistics are calculated based on all sampled data, graphs Average Transaction Response time is usually the default is calculated based on the data points in the chart; Workaround: Change the statistical sample space of the graphs Average Transaction Response time chart from "graph Minimum/maximum/.../average" to " minimum/maximum/.../average "; Operation guideline:analysis> Select inconsistent chart items >view>legend Columns options> Check/uncheck according to need; Note: This issue may also be caused by think time, and whether the filter setting containing the think is likely to cause the problem.

Note: LoadRunner faithfully recorded the interaction of the test script we wrote with the server,controller statistics are real-time temporary, analysisof the statistics is more flexible, can be adjusted according to the statistics of statistical granularity and statistics required data sample space, The statistical items that may be required depending on the purpose are different so the two inconsistencies above may not necessarily need to be consistent, depending on the purpose of the analysis, for example, sometimes the need for specific data distribution for analysis of the data collected only for a specific sampling frequency needs to be The graphs Average Transaction Response Time Chart Statistics item is modified to "graph Minimum/maximum/.../average".
