Cause
ECS is newly Installed. The application does not send I/O to nodes that are missing from the Advanced Monitoring - Data Access Performance - by Nodes drop-down list.
Resolution
- Verify that there is no S3 or CAS I/O to Node(s):

- If there is no I/O to Node(s) missing from the Advanced Monitoring - Data Access Performance - by Nodes drop-down list, this is normal behavior.
- Once I/O is received on Node(s) missing from the drop-down list, Node(s) should appear on the drop-down list.
