Interview Prompt
The platform team is reviewing the machines in the us-east-1 region and wants to see how hard each one is working. For every node in us-east-1, list its hostname and CPU load, mark whether it is busy or idle, and show the current number of active user accounts alongside each node.
Summary
Being in the region and being active are two very different things.
