Why does the Controller fail the Health Check with Status: Critical when it's installed with DB Aurora RDS?
Issue
When a Controller is installed into an AWS EC2 with Aurora RDS, the bin/platform-admin.sh show-service-status --service Controller returns the following status, even though the Controller checks out fine in all of the logs:
Health Status: Critical Health: Critical
Why is this happening?
This appears to be an issue in the health check mechanism and is being investigated by engineering.

Why does the Enterprise Console fail memory prerequisites when the Controller is installed in AWS Aurora?
Issue
The Enterprise Console prerequisite checks on the resources of a large profile Controller when it is installed in an AWS EC2 size r4.8xlarge fail with the following message:
Detected only 242588 MB of free RAM. 524288 MB of free RAM is required for this installation. Increase the free RAM and retry this operation.
The recommended size for a large profile for Controller EC2 on AWS is Instance Size r4.8xlarge, which equals 244 GiB memory. However, a large profile Controller requires 512GB. When choosing Aurora, this check should be bypassed (but is not). Our engineering team is currently investigating this.
Workaround
A work around for this is to modify the controller_min_ram_in_mb parameter in the Enterprise Console controller-large.groovy file.

1 Kudo
There is an internal agent built into the AppDynamics controller.
It is accessed as follows:
Logout from the controller
Launch the following URL and login with the following credentials
<Controller_url>:8090/controll er?enableAccounts=true
Account = system
Username = root
Password = <root_user_password>
Can anybody explain how this agent can be configured i.e. if the Account: System - Application flow map is blank? [ V4.4
On-premise (AWS)]
