![]() If this service is off, or failing, Device performance & health will let you know so you can fix it. ![]() Windows Time service automatically synchronizes your system clock to an internet-based time service so your system time is always correct. Windows Time service - Having your system set to the correct time is important for a lot of system processes. Storage capacity - Is your system running low on disk space?Īpps and software - Is any of your software failing, or in need of an update?īattery life - Is anything putting an extra strain on your PC's battery? You might not see this on on a desktop PC that is always plugged in. The time displayed should be basically the current time, as Windows Security tries to run a Device Health scan when you open the Device performance & health page.īeyond the time of last scan you'll see the status of the key areas that Device Health monitors: The Health report starts off by showing you the last time a Device Health scan was run. From time to time, functions are added or updated.Note: If your device is managed by your organization, your administrator may not have granted you permission to view Device performance & health. This API enables capturing kernel stack traces, merging multiple trace files for analysis, and including system information in the merged files. No public API is available for the current version of WPA. However, it is obsolete, and new profiles should be created using the current version. This API is an extension of the ETA Event Tracing API and is supported for backward compatibility with existing scripts and profiles. The Kernel Trace Control API Reference covers the Kernel Trace Control API available in previous versions of WPA. See wpr -help start for more information.Īfter recording a trace, you can now immediately open it in WPA by choosing the Open in WPA button.ĭirect handling of CLR symbols, so no flags are necessary when configuring and using NGEN support Start command now supports shutdown tracing to persist over reboot. See wpr -help profiles for more information. When saving a ETL, Ctrl + C can be used to cancel a in progress save.Įxport profile command enables exporting of built-in profiles to be used as a starting point for building a custom Windows Performance Recorder Profile (*.wprp). Merge command enables merging of ETL traces (similar to XPerf's merge command). ![]() New for Windows Server 2022 The WPR command line has gotten a few new features and updates to improve your developer analysis: Windows Performance Recorder (WPR) is a performance tool that you can use to record system events that you can then analyze by using WPA. Support for multiple traces in a single session Stack tags for creating labels that help you better identify which parts of the call stack(s) are affected Regions of Interest that allow you to highlight important time ranges in a trace Point in time rectangle viewer that allows you to visualize what happened on the screen during your trace ![]() New version of the File menu (called Rich Menu) with the option to switch back to the Classic Menu Rich text support for the Analysis Assistant that lets you format your text to make it easier to read and parse, as well as add links to reference materials, videos, or more detailed help pages on the web. When using the assessment console, make sure to select the assessment file.Īnalysis Assistant pane that displays helpful content to help you determine how to best use a given graph, preset, or analysis tab.URI (wpa://) only works for assessments files. These columns can be manually added via the View Editor. Regions Table not auto adding field columns. Symbols Load progress can appear to be hung or stuck, but symbols will continue to load. To work around the issue, load symbols first before interacting with tables. ![]() Symbols Columns can become stale when Symbols are being loaded: Since most of the code has been rewritten from the ground up, here are a few known issues: NET Core 3.1 application, allowing for extensibility by loading plugins to process any specific data sources (outside of ETL). With the rewrite, WPA is now a self contained. New for Windows Server 2022 WPA's code structure and tooling has been rewritten with early support of the Performance Toolkit SDK. Windows Performance Analyzer (WPA) visualizes traces from Windows Performance Recorder and Windows Assessment Console as graphs and tables to allow you to analyze system and application performance. To ensure proper installation, run setup.exe instead of trying to install the packaged MSI. The Windows Performance Toolkit installation is split into multiple MSI. ![]()
