It shows instances assigned to your application with some information and controls:
- Average Queries Per Second (QPS) over the last minute
- Average Latency over the last minute
- The number of requests received in the last minute
- The Age, or how long the instance has been running
- Current memory usage
- The instance's availability, either resident or dynamic.
- A Shutdown button to shut down the instance.
