PerfView Version 1.9 Released to the Web

 

Today I have updated the PerfView Download Site, to version 1.9 of the program.   In particular this version has a fix for a symbol resolution on data collected from older (e.g. Win7 OSes) machine that I mentioned in a previous blog post.    It also has a number of other notable features

  • Generalization of Thread Time views support arbitrary requests demarked by user defined Start-Stop events
  • Significantly improved support for Async and Parallel activities in the 'Thread Time' Views
  • Can display file disk usage in the stack view using the Size -> DirectorySize option
  • Supports reading a very simple *.PerfView.XML or *.PerfView.JSON file, which enable reading data from 'foreign' profilers.
  • Support for Windows 10 self describing ETW events
  • Support for EventSource causality tracking
  • Support for V4.6.2 .NET Runtimes that line number level on NGEN images (e.g. the framework) even if IL PDBS are not available when NGEN images were created

Some of these features need a bit of a 'walk through' to show how useful they are, so I will be blogging about that in the days and weeks ahead.  

In particular you can now view data that was collected on a Linux machine or consume data from other 'foreign' profilers (or other hierarchical data sources).  

If you are new to PerfView the easiest way to get going is to simply download it (you are only a few clicks away).   Or for the less adventurous, you can watch some of the PerfView videos on channel 9.

    @Fabio use the NuGet Version: www.nuget.org/.../Microsoft.Diagnostics.Tracing.EventSource

    @Fabio.  Please don't use the Nuget package on UWP apps as Andre advised.  UWP already has the latest, and your app will simply be bigger and slower (and there are possible sublte bugs since we don't test that configuration).   Buyt to answer your question, yes, EventSource exists in the .NET RUntime used by UWP apps (System.Diagnostics.Tracing.EventSource).   However it sounds like you are trying to extend it using native code (C++?).   That does not work (as you found out).  It has nothing to do with EventSource per-se,. EventSource is really for when you are in C# or VB.  For native languages the suggestion is to use TraceLogging (see msdn.microsoft.com/.../dn904636(v=vs.85).aspx)

      ok, thanks. I never coded an UWP app, so I was not aware of it.

    Hi, not sure where to report bugs, so I'm pasting it here: https://social.msdn.microsoft.com/Forums/exchange/en-us/b177d1db-553b-464c-be4d-2f6dd3a746fc/perfview-bug-when-selecting-time-range?forum=wptk_v4 It's bug about selected time range. Quite annoying when working a lot with time ranges because it resets quite often. Any possibility to fix it in future version(s)?

    Hi Vance,I use the following command to collect GC events:perfview /GCCollectOnly /NoNGenRundown /AcceptEULA /nogui /MaxCollectSec:600 collectCould you please suggest how to add stacktraces for GC event while keeping the size of the trace relatively small.Thank you.

    On the PerfView 1.9 download page, the Additional Information section says "For questions and/or discussion please visit the CLR Developer Tools Forum". However, MSDN Forums nowadays classifies that forum (netfxtoolsdev) under "Archived Forums A-B", and the most recent post is from January 2013. Is the advice on the download page still valid or should some other forum be used instead?

    Any chance of getting -InMemoryCircularBuffer working in Win7 / 2008R2 ?Is it even possible with win 6.1 ETW infrastructure? (I've not tested WPR yet)I'm getting this in win7 :[EXECUTING: PerfView collect /nogui -InMemoryCircularBuffer -MaxCollectSec:5]...Error stopping Kernel session: System Tracing is only supported on Windows 8 and above.Aborting tracing for sessions 'NT Kernel Logger' and 'PerfViewSession'.Strange, it tries to stop and yet it never logged a start like it does when you do not try to use a memory circular buffer :[Kernel Log: C:\bin\PerfView\PerfViewData.kernel.etl][User mode Log: C:\bin\PerfView\PerfViewData.etl]The point is to use it in win7 / 2008R2 in "in memory" flight recorder mode so as to not use disk at all in the first part of the capture (of course after stop it it must save to disk).

      I've tested WPRUI ( from ADK 8.1) in Win7 and it works with in memory circular buffer, so I don't think it needs windows 8 for that. Why PerfView does ?
