![]() This is a thoughtful gesture but sometimes, well, a stumbling block. Most other application require the user to provide the logger name (session name) to control the session but WPR gives you the default one unless specified. Other ETW tracing applications such as Xperf, and Tracelog call the session name as “ LoggerName“. In ETW tracing world, the session name is a steering wheel to the session, directly related to the tracing handle. When you start a trace, WPR is starting a trace “session” on your behalf and gives it a session name. This is because WPR uses the instance name to be the part of “session name”. Unless you give another instance name, WPR won’t allow to run another instance simultaneously if the instance name is same. When you start WPR, it gives the default instance name, “WprApp”. WPR assigns an “instance name” to an instance of the app. Another case, a user tries to open a second WPRUI, while WPRUI is already running in the background. This error usually happens when a user executes WPRUI, has the window open, then executes WPR CLI to try something else. This error can happen on both CLI and UI. One thing that stumbles the new WPT users is E_WPRC_DUPLICATE_INSTANCE_RUNNING error (0xc5580601). Provides hardware counter utility functions.Ībove list are not the whole list but the popular electives.Start/stop/cancel boot traces (autologger).Exports built-in profile to a custom profile.Displays detailed information about profiles.Show detailed status of trace including profile name, collectors, and providers.You can only do these things through CLI built-in) profiles.Įverything else are provided by CLI. The common factors of both CLI and WPRUI are: However, if your needs are versatile and you want to ride the car for a long time, then you would probably want to choose a high-end car though it is manual. If you drive only to near-by groceries and the office via well-known highways you can do that with WPRUI. WPRUI is an entry level automatic sedan whereas WPR is a high-end manual transmission car. They both share the same dll but not all the features can be accessed through UI. WPR comes in two flavors, WPRUI(wprui.exe) and CLI (Command Line Interface, Wpr.exe). You may want to make sure the installed version of WPR is used vs. The installation directory is: C:\Program Files (x86)\Windows Kits\10\Windows Performance Toolkit. (Optional) Add the installation directory to %Path%.Windows Performance Toolkit in ADK installation Select “Windows Performance Toolkit” during ADK setup unless other tools are needed.Of course, if you use Windows 8, or Server 2012, download Windows ADK for windows 8.1. “Insider Preview” version ADK provides the latest binaries whereas specific version gives you “official”. Go to and download the Windows ADK for Windows 10.To make it easier, here are the steps to install. If you want to use the user interface version of WPR (WPRUI) or other tools that come with WPT, then the MSDN doc would help you get started. If you want to just use wpr.exe command-line tool, it is included in the OS (Win10 or above). Someone who likes to poke around new tools.Testers who wants to measure performance of apps or drivers.Program manager who wants to profile performance of apps or drivers.Software engineer who wants to diagnose his/her apps or drivers.I hope that this blog series would help a variety of engineers by providing background and guidance without drilling too much into the technology behind. Without that knowledge, WPR’s commands, options, and profiles are a foreign language that you have never heard of. However, WPR requires knowledge about Event Tracing, and trace providers to apply manual control over the tracing session. Just bring up Command prompt, and you can start typing WPR commands such as wpr -help. Thankfully, WPR is very lightweight which allows it to ship with Windows OS. WPRUI – Windows Performance Recorder User Interface application.WPR – Windows Performance Recorder Command-line application.Windows Performance Toolkit (WPT) is included in Windows Assessment and Deployment kit.īefore we go too much into the article, here is the list of acronyms to be used frequently. ![]() ![]() As one might guess from their names, WPR “records” a trace and WPA visually “plays” the trace so we can review the performance of components. The other one is WPA (Windows Performance Analyzer). WPR is one of the two main components of Windows Performance Toolkit. WPR is an acronym for Windows Performance Recorder, which records ETW(Event Tracing for Windows) traces. It is hard to start a new blog series without an intro. ![]()
