I read on some other sites that IIS creates 1 w3wp.exe process for each application pool. My server has 5 app pools, and 2 of them have an application. But in task manager I only see 1 w3wp.exe. Can anyone explain why?
Here is a screenshot:
Run the following command at command prompt and you get even more info,
%windir%\system32\inetsrv\appcmd.exe list wp
Then you will see which worker processes belong to which application pools.

If I make changes to anything under the Features View for a website in IIS, do I need to
recycle the AppPool to get those changes to take effect
for any browsers already opened to that website should the tab be closed or a new tab be opened, or does the browser should be closed and reopened to see those changes?
I would like to the difference between iisreset, AppPool Start/stop, AppPool Recycle, and Website Restart options? Is there a good recommendation where I can read about this?
iisreset: stop and start the World Wide Web Publishing Service.
AppPool Start/stop:
start: starting an application pool enables IIS worker processes to be created to serve requests in that pool.
stop: instruct all IIS worker processes serving this application pool to shut down, and prevent any additional worker processes from being started until the application pool is started again
AppPool Recycle: IIS will create a new process (keeping the old one) to serve requests.
Website Restart: stop and restart serving requests for that particular website.
SQL Server Profiler is showing me the process Id for a particular database accessor.
Windows Task manager shows me that that process Id belongs to W3wp.exe.
How can I tie this back to the web application? (I have multiple web applications running on this server.)
You could use the iis manager worker process feature to check which process belongs to which application.it shows you all running worker processes and some basic info, including ProcessId.You can match that ProcessId to the Processes tab in Task Manager.
1)Open iis manager, select the server node.
2)Double click on the worker processes feature.
another thing you could try is run below command. it will show the process with the application pool name:
%windir%/system32/inetsrv/appcmd list wp
I have an asp.net mvc application deployed in IIS. Sometimes its application pool worker process hangs so I would like to know if there is a way to monitor a specific IIS worker process using windows performance monitor? If so, what indicators I have to monitor?
As far as I know, we could add counter in the process monitor to figure out the Process identifier of the process.
You could right click the performance window and select counter.
Then you could choose the was_w3wp and select the process id w3wp process.
I have a doubt on IIS 6.0 worker process and Application pool.
I am having two web application which is been hosted on IIS 6.0 with different port number. Also I am created and assigned an Application pool to that applications. That application pool has configured for 2 worker process. Now what is my question is? when I am running that two applications from the browser, How that application pool will handle them? whether that two worker process will be assigned to one application or both.?
Please share your idea...
Thanks in Advance...
The worker processes are specific to each application pool. If you specify one application pool to have 1 worker process it will have only 1 worker process. If you specify another application pool to have 2 worker processes it will have 2 worker processes. You should notice that the properties screen is specific to an app pool.
You can see which application pools are using which worker processes using the following process;
• Start > Run > Cmd
• Go To Windows > System32
• Run cscript iisapp.vbs
• You will get the list of Running Worker ProcessID and the Application Pool Name.
You should see that if one of your app pools is set to use 2 worker processes it will have two entries in the list against the same app pool name.
Instructions and reference for above and also listing running worker processes in IIS7.
In my IIS log, I found warning level event ID 1013, which says the stop time exceeds expected stop time for worker process of a specific web application.
My question is, how could I know or track from what reason IIS worker process stops? Does this warning level event ID means worker process application pool is stopped or not?
thanks in advance,
George
If you application is an ASP.NET (2.0 or newer) you can turn on health monitoring which shoudl record details including IIS applciation pool resets.
