I'm very new to appdynamics and I had make its implementation asap

I'm running a k8s cluster in minikue right now and configured the cluster agent through Helm chart
I assume there is some issue with the values I have set in the values.yml file

controllerInfo:

url: "https://xxxxx.saas.appdynamics.com:443"

account: [Redacted]

username: [Redacted] ( or complete email address should be used ?)

password:

accessKey: (no issue in that I have verified it twice)

please help in resolving the issue

Hi Hassan,

This is a generic 401 authentication problem. When you send metrics or valid messages from agent to controller there are several things you have to configure properly below

host, port, account name (default "customer1" if you don't use the controller in a multi-tenant mode), and account key.

So basically there are 2 reasons that you need to focus.

First can you please control this step below given, and try again?

To create a secret with a Controller access key:

$ kubectl -n appdynamics create secret generic cluster-agent-secret --from-literal=controller-key=<access-key>

Thanks

Cansel
