Hello, I got an issue with .net agent 188.8.131.52. it does not display front end and back end components in investigator. everything installed is as default so I am expecting the default URL Grouping configuration in introscope agent profile will produce a frontend and a backend component but it does not. It only display a tree like :
Anyone with the knowledge or experience can you please advise ?
What you have is the default PerfmonCollectorAgent showing up, which would only display perfmon metrics.
Application metrics would be reported only by .NET Agent and it seems like either it's not properly configured or perhaps having issues monitoring application.
Check if there are any errors in Windows Event Viewer related to Agent startup.
Thanks for the reply, just a second thought, could this be due to application is running as unmanaged code ? I can see in IIS application pool is configured as “No Managed Code” in .Net CLR Version.
Yes that would explain it.
The .NET agent can only instrument managed code where the CLR is being loaded i.e. .ASP.NET (.aspx) compared to the unmanaged ASP classic (.asp)
If this is a new agent install it sounds like the IIS process is still not loading the agent assemblies whereas the Perfmon Collector we supply is loading them successfully.
There are some knowledge documents that cover troubleshooting .NET Agent problems and you can search for them here:
Troubleshooting a 9.1.x .Net Agent Installation
.NET Agent installation problems - Checklist
If all else fails you may need to restart the actual server.
Hope this helps
