Read this instruction if you need understand how to load symbols or configure symbol paths in WPA. The paths of symbols can be added either from UI, or by setting environment variable _NT_SYMBOL_PATH. WPA supports loading symbols so you can see more details of each process or command. This graph is a process lifetime graph generated by WPA. To see the graphs, just drag the graph to the “Analysis” tab on the right side.Ĭomparing to Performance Monitor (perfmon), WPA reports give you more details and flexibility to explore the data. In the left “Graph Explorer”, you can choose to view performance graphs for System Activities, Computation, Storage, Memory, and Power. WPA provides detailed performance analysis data in its rich user interface. If “Save” is clicked, the performance data will be stored to files, and Windows Performance Analyzer (WPA) will be automatically launched to show the performance reports. The recording will end when you click the “Save” button or “Cancel” button. Then you can start recording performance by clicking the “Start” button. You can follow the instructions here on Microsoft Docs to decide how to choose for your needs. When WPR starts, it will guide you to choose a few configurations: profiles, scenario, details level and logging mode. This tool is included in the Windows Assessment and Deployment Kit (Windows ADK), and you can download it here. It records system events that you can then analyze by using Windows Performance Analyzer (WPA). Windows Performance Recorder (WPR) is a performance recording tool that is based on Event Tracing for Windows. The other graph types you can choose are: Line, Histogram bar, Area. The following is one example of displaying performance report in Stacked Area Graph. The report can also be viewed as graphs in the Performance Monitor. The recorded data will be shown in the Reports session in the left panel. With the added Data Collector Sets, you can start recording before running your application, and stop recording any time you want. If the process you are monitoring takes longer than 1 minute to finish, you definitely want to increase this “Overall duration” to some longer time. With this condition set, the performance recording will stop in 1 minute after starting. By default, a newly created Data Collector Sets has “stop condition” as “Overall duration: 1 minute”. There is only one thing that you need pay attention to: the Stop Condition. The process is quite straightforward as provided in the GUI. Perfmon allows you to choose a template to start with, and specify the location where the performance data will be saved. We can do this in perfmon by adding User Defined Data Collector Sets (from Menu Action -> New -> Data Collector Sets). When analyzing an application’s performance, we often need record all the performance data and generate various reports to help analysis. You can add more counters you need, such as Processor’s Idle Time, Cache Performance, Network Performance and a lot more. To view current performance activity, you just need click on the Performance Monitor button in the left panel:īy default, this view has only one performance counter: % CPU Processor Time. This tool provides some extremely useful interfaces in its GUI. With perfmon, you can monitor real-time system performance, and record performance to files for post analysis. Performance Monitor is a small utility provided by Windows OS, you can start it by running command perfmon. Last week I was working on profiling and analyzing the build process of a project on Windows, and during the process I experimented with a few different tools. Today I’m going to write about a few Performance profiling tools on Windows platform. Sigcheck v2.03: This version corrects a bug that caused the output of the –u switch to include signed files, and fixes several other minor bugs.Last year, I wrote a blog post about CPU Profiling and the tools on Linux. PSExec v2.1: This update to PsExec, a command-line utility that enables you to execute programs on remote systems without preinstalling an agent, encrypts all communication between local and remote systems, including the transmission of command information such as the user name and password under which the remote program executes. Process Monitor v.3.1: This release adds registry create file disposition (create vs open) and a new switch, /saveapplyfilter, which has Process Monitor apply the current filter to the output file as it saves it. Process Explorer v16.02: This minor update adds a refresh button to the thread’s stack dialog and ensures that the Virus Total terms of agreement dialog box remains above the main Process Explorer window. Microsoft Sysinterals has updates Process Explorer v16.02, Process Monitor v3.1, PSExec v2.1, Sigcheck v2.03 :
