Hello, I have a free version of the machine agent running on CentOS configured with the SaaS version of the cloud controller. The agent starts and connects to the controller. I also see the server listed on the controller. However, I don't any metrics visible under the Metric Browser. Can you help me troubleshoot this
Machine agent version: 20.10.0.2813
CentOS 7.8
Controller: https://[Redacted].saas.appdynamics.com/
Here is some observation that may / may not be related. I will provide config/logs if required.
1) When I reload the controller, sometimes, I see "500 Internal Server Error" reported.
2) I see this in the machine-agent.log
[ExtensionStarter-DockerMonitoring] 04 Nov 2020 14:39:29,269 ERROR CGroupFileSystemRootProvider - Could not find CGroup files in following path(s) : [/sys/fs/cgroup, /cgroup]
3) I see this in analytics-agent.log
[2020-11-04T14:54:02,464Z] [ERROR] [analytics-agent-sync-thread-0] [c.a.a.agent.sync.ErrorMessageHelper] Analytics agent failed to connect to the controller registration endpoint. This can happen when the connection is refused remotely, or when there is no process listening on the remote address/port. Please check to see if the controller address is configured correctly and is running.
4) I have server-monitoring disabled, I wasn't able to get the agent started with this enabled.
( <sim-enabled>false</sim-enabled> in controller-info.xml)
Thanks

Have you checked out this KB article Why is there no data in the Metric Browser?
Please let me know if that provided any help.
Thanks,

Thanks, Ryan for looking into this. How does one access this folder on SaaS (cloud) instance?
<controller_home>/logs
Copying Tim.Gillin & @Krishna Rathnam.Desikan
Thanks, Nram

Based on the following link, I had to add some additional tags in the controller config. Krishna pointed out that this is required for standalone controller configuration.
https://docs.appdynamics.com/display/PRO44/Standalone+Machine+Agent+Configuration+Property+Reference
I added the following to my controller-info.xml and that resolved.
<application-name>myapp</application-name>
<node-name>mynode</node-name>
<tier-name>mytier</tier-name>
Thanks Krishna and Ryan for the help.
