SYSU: Node Start
When a service is restarted, this message is generated to indicate if the previous shutdown was clean (commanded) or disorderly (unexpected).
The nature of the shutdown:
SUCS: System was cleanly shut down.
DSDN: System was not cleanly shut down.
VRGN: System was started for the first time after server installation (or re-installation).
The message does not indicate if the host server was started, only the reporting service. This message can be used to:
Detect discontinuity in the audit trail.
Determine if a service is failing during operation (as the distributed nature of the StorageGRID system can mask these failures). Server Manager restarts a failed service automatically.
