A node can have one of the following states:
Online - The node is available.
Offline - The node is not available.
Configuring - The node is being launched for the first time, or an AMI (Amazon Machine Image) version update is taking place.
Setup failed - The configuration failed. Auto-launching the connector will be retried until success, or until aborted manually.
Upgrading - A connector version update is ongoing.
Preparing - The node is after a reboot, before returning to online state.
