Sorry you are having trouble with the NR-Diagnostics tool. I’ll note the error you reported and pass it on to the development team. But, rather than troubleshooting the troubleshooting tool, we should probably just look directly at your installation and see if we can troubleshoot it that way.
Can you tell me a little about the app you’re trying to monitor?
- Is it an ASP.NET web application, or a console/service application?
- Is it a .NET Framework application or a .NET Core application?
- Do you get new log files created in the agent logs folder when you restart your application? The logs folder is at
C:\ProgramData\New Relic\.NET Agent\Logs for the .NET Framework agent. For the .NET Core agent, it should be in the folder where you extracted the agent on your system.
If you’re not seeing any logs in the agent logs folder (or if the logs folder doesn’t exist) take a look at this article to start troubleshooting the issue.
Let me know if you have questions.
