AWS provides access to EC2 system logs. Add a button triggering a popup pooling the console stream

In the the subscription wizard, while searching for a VM, got a NullPointerException.
These error disappear when terminated instances are removed from the list by AWS cleanup sub-routine.

When we are adding new aws instance, the suggest field shows also instances where have just been destroyed. I think you should use the action DescribeInstanceStatus or add a filter instance-state-code (multi value ??) to suggest only available instances.

Instead of console page, points to the EC2 page :
Sample :
https://eu-west-1.console.aws.amazon.com/ec2/v2/home?region=eu-west-1#Instances:instanceId=i-0ee0000eeee0e0000;sort=tag:Name

Pattern :
https://$az.console.aws.amazon.com/ec2/v2/home?region=$az#Instances:instanceId=$id;sort=tag:Name

EC2 provides alarm checks, get this status if defined and add a tick or a red cross depending on the result.
