Wrong report data: memory instead of CPU and vice-versa

Question

Hello,

I've been fighting with VS 2010 SP1 for a while. I have a Silverlight project that is hosted in a web application run under IIS 7. I try to profile the web project and collect CPU usage samples. The profiler runs successfully, but when I open the result .vsp file in the VS, it analyzes it and renders a memory usage report without any data on CPU usage. I've tried to switch the performance session to Sampling, Instrumentation, Memory allocation sampling, but in any case I get a memory usage report instead of CPU usage report. Running the command-line VSPerfReport gives similar reults with only memory allocation data.

If CPU Sampling is selected, the VSPerfMon is started by VS with the following command arguments

-output:"<xxx>.vsp"
-SAMPLE
-WINCOUNTER:"\Processor(_Total)\% Processor Time"
-WINCOUNTER:"!\.NET CLR Exceptions(%s)\# of Exceps Thrown / sec"
-WINCOUNTER:"\Memory\Pages/sec"
-WINCOUNTER:"!\.NET CLR Memory(%s)\# Bytes in all Heaps"
-WINCOUNTER:"!\.NET CLR Memory(%s)\# Total committed bytes"
-WINCOUNTER:"!\.NET CLR Memory(%s)\# Gen 0 Collections"
-WINCOUNTER:"!\.NET CLR Memory(%s)\# Gen 1 Collections"
-WINCOUNTER:"!\.NET CLR Memory(%s)\# Gen 2 Collections"
-WINCOUNTER:"!\.NET CLR Memory(%s)\%% Time in GC"
-WINCOUNTER:"\Processor(_Total)\% Privileged Time"
-WINCOUNTER:"\Processor(_Total)\% User Time"
-WINCOUNTER:"!\Process(%s)\%% Processor Time"
-WINCOUNTER:"!\Process(%s)\%% Privileged Time"
-WINCOUNTER:"!\Process(%s)\%% User Time"
-WINCOUNTER:"!\Process(%s)\Private Bytes"
-WINCOUNTER:"!\.NET CLR LocksAndThreads(%s)\Contention Rate / sec"
-WINCOUNTER:"!\Process(%s)\Working Set"
-AUTOMARK:500
-USER:"IIS APPPOOL\ASP.NET v4.0"
-CS

I've tried to use an experimental instance of VS (with the help of VS 2010 SP1 SDK), but the result is the same.

 

Please, help identify and fix the issue. Working without profiler is pain.

 

Update: When I tried to profile the Silverlight application that is hosted in the web app and I needed memory allocation results, VS rendered CPU usage report.

Seems like some issues with environment, but I don't know how to diagnose them.

Thank you for your post, we're investigating on this issue, it might take some time before back to  you.

I have similar issue, the Visual Studio always generates memory profiling report instead of selected one (eg. cpu report).

Visual Studio 2010 SP1, Windows 7 SP1 x86

Hint: VSPerfMon.exe and immediately after devenv.exe crashed when I selected memory profiling first time. From this time, it always profiles memory. I tried everything, restarting, deleting of profiler files,...

I remember that my issues also began after a crash during profiling (seems like it was first attempt of memory profiling as well). Although I can't give exact details and cannot find related messages in the log.

Answer 4

Hi Pavel,

Does this issue consistently occur on all projects or just that specific Silverlight project? Have you tried reinstall profiler (http://www.microsoft.com/download/en/details.aspx?id=23205)?

Answer 5

Hi Leon,

Does this issue consistently occur on all projects or just that specific Silverlight project?

As I've written above, I have a Web Application project that always gives me a Memory report and a Silverlight project that always gives a CPU report. If you ment this, these are two different projects, although they are in the same solution and are somehow related to each other.

I've just tried to create a new solution with default Silverlight project template (Silverlight application + Web application) and test the profiler on it. In this case, the web application is hosted on Cassini instead of IIS. I used the wizard and created a CPU sampling session against the web application. When I started profiling, it first asked Administrator priviledges (the message said it couldn't access the profiler driver). When I stopped the session, VS rendered Memory profiling report (instead of CPU). So, the results coincide between my real solution and a clean one.

Should I do some other tests, probably with other project types?

Have you tried reinstall profiler (http://www.microsoft.com/download/en/details.aspx?id=23205)?

No, I haven't. I will do when I have time to dive into the problem again and if there are no other workarounds.

Answer 6

OK, I have installed the x64 profiler package (it was new installation, not reinstallation - I had not got the standalone package installed earlier). It didn't help.

 

Then I tried to switch to Concurrency profiling (just trying to change bad settings stored somewhere). After the profiling was finished, VS showed the following error:

Error VSP1713: Incompatible collection settings for C:\Projects\Allegro\Source Code\HSI+Main-Root\AWDB.SL\AWDB110722(3).vsp. Cannot collect memory and concurrency data at the same time.PRF0025: No data was collected.

 

Several settings in environment are definitely incorrect...

Answer 7

An issue has been reported that seems similar: http://social.msdn.microsoft.com/Forums/en/vstsprofiler/thread/d42a22ea-ce41-4e86-a9c1-6f1e34fabe08

As time passes, I've tried to reinstall the x64 profiler package - no luck.

I've found several environment variables that were related to profiling (starting with COR_) and removed them. Even after reboot that didn't help.

I've tried to use VSPerfCLREnv.cmd to switch the variables: enabled simple and global gclife modes, then turned all of them off several times. Again, no luck.

 

I don't want to reinstall the neither VS nor the OS. I do need the profiler working.

Are there any diagnostic procedures I might carry out to help find the reason of the problem?

Answer 8

It is hard to guess what exactly happen without a repro.

Another thing we can try is to reset VS to default settings (http://msdn.microsoft.com/en-US/library/ms241273(v=VS.80).aspx) or launch VS in safe mode (http://msdn.microsoft.com/en-us/library/xee0c8y7(v=vs.80).aspx ). Though I doubt it helps.

Answer 9

I'm experiencing the same problem, and it's a royal pain.  Rendering one of the most valuable features of the more expensive VS SKU's useless is not a great way to elicit customer "delight".  I suspect this is a widespread problem in a not-so-widespread feature.

Answer 10

Anyone get this solved?   I first had this issue, now I'm experiencing the lovely VS crash when doing an analysis of a vsp.

Really not feeling warm and fuzzy at the moment ...
