I'm attempting to get an AWS EKS cluster instrumented with an AppD agent running against a SaaS instance.

I have followed the instructions here: https://docs.appdynamics.com/appd/4.5.x/en/infrastructure-visibility/monitoring-kubernetes-with-the-... as well as other guides.

The containers are running, but I get this error in the cluster agent logs:

[ERROR]: 2022-08-17 01:06:57 - agentregistrationmodule.go:131 - Failed to send agent registration request: Status: 404 Not Found, Body: <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head><title>Error report</title><style type="text/css"></style> </head><body><h1>HTTP Status 404 - Not Found</h1><hr/><p><b>type</b> Status report</p><p><b>message</b>Not Found</p><p><b>description</b>The requested resource is not available.</p><hr/></body></html>

I have available Server Visibility licenses so that isn't the issue.

What can I do to get this working?

I ended up having to work with AppD support on this one.

After some troubleshooting, we found that the controller URL in my cluster-agent.yaml file was incorrect.

I had a trailing slash and needed to specify the port, which in my case was 443. After fixing the yaml I had to apply the new file and then delete the old pod to get it to accept the new configuration.

It ended up looking like this:

controllerUrl: "https://<account_name>.saas.appdynamics.com:443"
