![]() ![]() The remainder of this section refers to the documents and scripts that are WPA is available in the Windows Assessment and Deployment Kit (Windows ADK)ĭownload package and includes scripts and documentation for Modern Standby For more information about the PDC Resiliency Activity graph andĭevice Dstate graph, see the " View a WPA trace" section " Common WPA graphs for connected standby power management" To spend too little time in the DRIPS state.įor more information about the Platform Idle State graph, see the Therefore, this action expands the same time interval for all those graphs.Watch this video to learn how to use the Platform Idle State graph and Deviceĭstate graph to track down a hardware device that causes the hardware platform You can repeat this step several times to see very fine detail of a very small time interval.Īll graphs on the Analysis tab use the same timeline. To do this, right-click the interval, and then select Zoom to selected time range. The timeline at the bottom of the tab applies to all graphs on the tab.Īfter you have selected a time interval, you can zoom in to expand that time interval to the full width of the Analysis tab. On the Analysis tab, you can select a time interval by dragging the pointer horizontally across a section of the graph. Drag the CPU Usage (Sampled) graph to the Analysis view panel. Now, expand the Computation graph in the Graph Explorer you will see CPU Usage (Sampled) graph under it. In the opened dialog box add path to the. To do that click on Trace->Configure Symbol Paths. The first thing you should do before starting any analysis is that you should configure symbol paths for your exe / server. Program execution begins and ends there.įor (int i = 0 i New Analysis View to open analysis view. Poor_performance.cpp : This file contains the 'main' function. Once the program finishes execution stop the recording and open the recorded file in windows performance analyzer. First, start recording session using windows performance recorder (WPR) and then start executing the following program. This function is used to demonstrate the memory leak analysis. Function memoryLeak() leaks some memory allocated on heap. The names given to these functions indicate the level of CPU usage. In the following program functions highCPU(), midCPU() and lowCPU() are CPU bound functions. Using this program you can do CPU usage analysis as well as memory leak analysis. You can use the following sample program to evaluate windows performance toolkit. Sample program to evaluate windows performance toolkit: Save your recording to the location you want. Click on the “Save” button to stop the recording. Then start your application server / exe for which you want to do performance and memory leak analysis.ħ. ![]() Now, click on “Start” button to start the recording.Ħ. Stop other bulky applications such as web browsers etc which you do not need, otherwise, those applications will also be tracked by WPR.ĥ. ![]() On the Start screen, click Windows Performance Recorder or from start menu search box execute command WPRUi. How to use Windows Performance Recorder:ġ. ![]() Windows performance analyzer is used to analyze the data collected by WPR. The collected data is then stored in a file. It can record all activities / events and resource consumption for the current session. Windows performance recorder is used to record windows session. Windows performance toolkit has two main components: Windows Performance Recorder (WPR) and Windows Performance analyzer(WPA). From the features list select only “Windows performance toolkit”, we do not need other tools for now. Invoke adksetup.exe which can be downloaded from Ģ. This is the official Microsoft docs link for windows performance toolkit Installing windows performance toolkit for performance analysis:ġ. In this article we will see how to use the windows performance tool kit to do high CPU utilization analysis and memory leak analysis. You can track almost all the OS resources like disk I/O, File I/O, Power usage, GPU activity, audio, video and many more. You can answer which function is leaking memory, where the network is getting stuck. Using this toolkit, you can answer which API / function of your server consumes high percentage of CPU time. Fortunately, now, Microsoft has come for our rescue with Microsoft performance toolkit. And most of the times we do not know the answers of any of those questions. Why the CPU utilization is near to 100% on my server machine? Why there is a steady decrease in the available memory? Why the calls are getting dropped? We often get these kinds of questions If we are from a performance upkeep team. ![]()
