Getting 401 unauthorized even after enabling SIM module in Appdynamics Container

[Christopher_Ant]

Hi Team, 

I am trying to run appdynamics machine agent as a container to monitor the existing app containers. I have gone through the issue discussion and added this line in my environment file. 

APPDYNAMICS_SIM_ENABLED=true

But still I recieve the error log:

Need solution on this.

This took me a "minute" to figure this one out. Turns out that in my controller-info.xml, at host tag, I had included an unnecessary fwd slash.  That corrupted my whole rest api url resolution. Check if that is not the case with you. As a general rule, keep host-name clean, port clean, and ssl option clean.

Hi @Christopher.Antonyraj,

Thanks for asking your question on the Community. I did some digging around and found these two AppD Doc pages. Please let me know if they help out at all.

https://docs.appdynamics.com/appd/22.x/latest/en/infrastructure-visibility/server-visibilityhttps://docs.appdynamics.com/appd/22.x/latest/en/infrastructure-visibility/monitor-containers-with-d...

If I find anything else, I'll share it with you here.
