Are you searching Google and BMC Communities for a solution, but could not find one?

 

Are you searching the BMC Support Knowledge Base and getting too many results for products you are not using?

 

Are you spending time having to unselect/select various products in the list?

 

Would you like to search the BMC Support Knowledge Base and only see results for just the TrueSight App Visibility Manager, BMC Real End User Experience Monitoring (Virtual and Software), Synthetic, PATROL for Application Management, or TMART products?

 

If the answer to any of the above is YES then you need to use a pre-filtered URL to just search for that particular product.  Also these pre-filtered URLs will contain additional KAs/solutions that are not available on Google and BMC Communities.  See the following steps to use these pre-filtered URLs to find solution to the problem or question:

 

Step 1) In a web browser, log into the BMC Support Central web site (Support Central - BMC Software)

 

Note: You must log into the BMC Support Central web site prior to using the pre-filtered URLs.

 

Step 2) Select one of the desired pre-filtered URLs in the table below and enter it into the same web browser in Step 1

When the App Visibility Agent for .NET is running then there should be two .dll files attached to the IIS worker process (w3wp.exe) within IIS.  To verify that these .dll files are bounded to the IIS worker process, perform the following steps:

 

Step 1) Download the Process Explorer utility at the following location:

 

https://technet.microsoft.com/en-us/sysinternals/processexplorer.aspx

 

and copy it to the server with the App Visibility Agent for .NET.

 

Step 2) Start the Process Explorer and click View -> Show Lower Pane

 

Step 3) Click View -> Lower Pane Window -> DLLs

 

Step 4) Look for the IIS worker process name called w3wp.exe and see if it is running.

 

Note:

An Internet Information Services (IIS) worker process is a windows process (w3wp.exe) which runs Web applications, and is responsible for handling requests sent to a Web Server for a specific application pool.  See https://technet.microsoft.com/en-us/library/cc735084(v=ws.10).aspx for more information.  This w3wp.exe process only appears in Task Manager if any of the web sites is being accessed by web browsers. It is not a service at all.  So you can start w3wp.exe by going to the IIS home page like http://<IIS_hostname_here>.

 

Step 5) If w3wp.exe is present then click w3wp.exe and see if the following two .dll files in the lower pane that belongs to "BMC Software, Inc." are present:

 

IisExtensionProbeHttpModule.dll

ClrProfInstrumProbe.dll

 

See screen shot below:

If either one of these .dll files are not present then stop the App Visibility Agent for .NET and IIS (or stop the application pool or pools instead of IIS).  Then start the App Visibility Agent for .NET first and then start IIS (or start the application pool or pools).  Perform the above steps again to verify if the two .dll files are present.

 

If the ClrProfInstrumProbe.dll file is only missing then the App Visibility Agents for .NET will not able to find/map web applications on IIS.  We need to confirm if the worker process (w3wp.exe) has the correct value for the COR_PROFILER environment variable.  Below are the steps to check the COR_PROFILER environment variable:

 

Step 1) On the server with the App Visibility Agent for .NET, start the Process Explorer utility

 

Step 2) Look for the worker process (w3wp.exe)

 

Step 3) Right click on the w3wp.exe process and select Properties

 

Step 4) Click on the Environment tab and look for the following two environment variables:

 

COR_ENABLE_PROFILING

COR_PROFILER

 

The value for COR_ENABLE_PROFILING should be 1.

The value for COR_PROFILER should be {FF51CB90-1C9F-4b50-BA41-D48BDE9823B0}.

 

If the value for the COR_PROFILER environment variable is not {FF51CB90-1C9F-4b50-BA41-D48BDE9823B0} then it means that another APM monitoring program is interfering with the App Visibility Agent for .NET and that other product needs to be uninstalled.
