Profiler won't start profiling

arf

I am not able to run Profiler on any of my ASP.NET web applications.

When Profiler is started it stops and restarts IIS and shows "Wating for connection" IE opens up with a Page cannot be displayed error" If I open IIS it shows that the default web site and the Default Application Pool as not being started (has an X next to it). If I manually try to start the default web site in IIS I get the following error.

IIS was unable to start the site. Another site may already be using the port you configured for this site. Please select an unused port for this site.

Profiler will remain indefinitley in a "wating for connection" state until the browser is closed. The same probelm occurs on all my different web applications (all running localhost on Port 80). I don't see any error message in the event viewer.

I am running Win2003 Sp1 Framework 1.1

Hi,

ANTS Profiler wants to profile the application based on the user that's running it in the case of ASP .NET. Unfortunately, it's still using machine.config to log in as that user so it can update the ASP .NET user's profile to allow application profiling.

Is the default app pool still running under the Network Service account, or have you changed the identity to something else?

arf

The default application pool is running under the Network Service account.

Uninstalling Ants Profiler 2.0 and re-installing Profiler version 1.3 build 147 cures the problem. Version 1.3 works with no problems.
It appears that the problem is with the 2.0 release or the 1.3 to 2.0 upgrade process.

Brian Donahue

Hello,

What does the machine.config file have in it for the particular version of the Framework that you're using as the apsnet user under the processModel section? Is it System, Machine, or a named user?

There could be a mismatch between the user information for the application pool and what's in machine.config. ANTS Profiler doesn't like it when that happens.

arf

From Machine config: (Note: I am running IIS 6, Win2003SP1)

When ASP.NET is running under IIS 6 in native mode, the IIS 6 process model is
used and settings in this section are ignored. Please use the IIS administrative
UI to configure things like process identity and cycling for the IIS
worker process for the desired application
-->
<processModel enable="true" timeout="Infinite" idleTimeout="Infinite" shutdownTimeout="0:00:05" requestLimit="Infinite" requestQueueLimit="5000" restartQueueLimit="10" memoryLimit="60" webGarden="false" cpuMask="0xffffffff" userName="machine" password="AutoGenerate" logLevel="Errors" clientConnectedCheck="0:00:05" comAuthenticationLevel="Connect" comImpersonationLevel="Impersonate" responseDeadlockInterval="00:03:00" maxWorkerThreads="20" maxIoThreads="20"/>
<webControls clientScriptsLocation="/aspnet_client/{0}/{1}/"/>

===============================================

In IIS Manager the Default Application Pool Identity "Security Account" is set to "Network Service"

Brian Donahue

That looks like a n unmodified machine.config to me. I'll see if I can find another reason for this.

I am having this same problem. I am running IIS 5.1. Windows XP Pro.

When I tell ANTS to Stop Profiling (and it is still "Waiting for Connection") I get the following exception

************** JIT Debugging **************
To enable just in time (JIT) debugging, the config file for this
application or machine (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the machine
rather than being handled by this dialog.

It looks like the ANTS Profiler hasn't loaded the COM component that serves as the back-end data collector.

Have you evaluated any other code profiling tools recently? Sometimes they leave environment registry entries behind that can have a negative impact on ANTS Profiler.

happyinst

No I haven't evaluated any other code profiling products.. but I did evaluate httpZip from Port80 software... http://www.port80software.com/products/ ... id=1899372 I am not sure if that would matter.

Is there any way for me to fix this?

Lori

Brian Donahue

I can suggest re-registering the ANTS Profiler component. That may help. Open a command prompt, cd to c:\program files\red gate\ants profiler and type 'regsvr32 redgate.profiler.core2.dll'.

Removing any traces from a previous profiler is a bit difficult, so please give that a try first.

happyinst

Thanks.. it is now profiling but I dont see any useful info from the Memory profile. All it lists as live objects are bytes and strings and it has no refernces to source code. Is that the way it is supposed to be?

I am profiling a web application. I have confirmed that I built it in debug mode.

Lori

Brian Donahue

Hi Lori,

All that you're probably going to see as a named object are the objects that were created in your code. Anything done by the Framework is going to be labeled something esoteric like System.Byte[].

I’m having the same problem profiling my asp.net application.
I’m running XP Pro and IIS 5.1
My aspnet_wp.exe process is running under a user name of ASPNET
My maching.config looks like this:
<processModel enable="true" timeout="Infinite" idleTimeout="Infinite" shutdownTimeout="0:00:05"
requestLimit="Infinite" requestQueueLimit="5000" restartQueueLimit="10" memoryLimit="60"
webGarden="false" cpuMask="0xffffffff" userName="machine" password="AutoGenerate" logLevel="Errors"
clientConnectedCheck="0:00:05" comAuthenticationLevel="Connect" comImpersonationLevel="Impersonate"
responseDeadlockInterval="00:03:00" maxWorkerThreads="20" maxIoThreads="20"/>

The profiler just sits there with the "Waiting for connection" message.
I did evaluate another profiler and I did run the regsvr32 command but still no luck.

I have loaded the latest VS 2005 beta which also installs the 2.0 framework, not sure if that matters or not.

Any ideas?

Thanks,
Ed

I believe Tom from Red Gate is going to get in touch with you soon with an offer to try the Beta of Profiler 2.1, which will support .NET Framework 2.0.

arf

After many hours of trying I am still not able to get ANTs Profiler 2.0 working for web apps running on my Win2003 IIS 6.0 development system. I found by running IIS in IIS 5.0 Isolation mode I was able to get it to launch my web applications, but no results are shown. When running in standard IIS 6.0 mode, I tried changing the identity of the default application pool from "Network Service" to Local System and Local Service, but neither setting made any difference. I confirmed that both ANTS and the w3wp.exe processes were running under the same identity when I tried this. I tried to change the identity within the machine.config but that did nothing either. The only way I can get ANTs Profiler to run on my system is to roll back to the 1.30 release.

Brian Donahue

Hello,

I believe that one of the sevelopers had sent you an advance copy of Profiler 2.1. Is that the one that's still giving your problems?

Tom Harris

Hi Arf,

I have sent details to your email account of how to download ANTS Profiler 2.1. ANTS Profiler 2.1 provides much more robust ASP.NET profiling and has worked for all our other 2.0 customers who were having problems. I would be most grateful if you could download and try out the new version,

Best regards,

Tom Harris

NB please note that 2.1 has not been officially released yet, we are running through final tests.
