Vault Connector Logs

Vault Connector logs provide detailed visibility into the synchronisation process between Autodesk Vault and Fusion Manage. These logs are essential for diagnosing sync failures, verifying task execution, and understanding the flow of item data across systems.

Where to Find the Logs

Vault Connector logs are accessible via:

ADMS Console – under Vault Connector settings.
Vault Client – visible in the Item Master, Item Record Dialog, and Preview Pane.

Common Log Events

Each log entry includes a timestamp, task ID, and status message. Below are typical patterns:

Event Type	Example Log Entry
Agent Start	`INF Agent message queue is starting...`
Token Refresh	`INF ApsTokenRefreshService is starting...`
Sync Initiation	`INF TaskId:50242 Sync Item start`
Metadata Missing	`INF No sync-item-info data available for 17543`
Sync Success	`INF TaskId:50242 completed with status Succeeded. Duration: 9.99 seconds`
Attachment Upload	`INF Upload attachment associatedFiles succeeded for Item(17543)`

Sync Status Indicators

Vault Items synced to Fusion Manage are tracked using three key properties:

Sync Scenario	Link State	Sync Status	Synced Date
Item never synced	Blank	Blank	Blank
Latest version synced successfully	Up to Date	Successful	Date & Time
Latest version synced but failed	Out of Date	Error	Date & Time
Latest version not yet synced	Out of Date	Blank	Blank

These properties are stored as entity attributes and reflect the latest sync status across item versions.
