Collect and review system data

Last updated: September 21, 2026Applies to current supported NIM releases

System collection guide

Collect current data into the Vault, validate the result, and use collection history when you need to investigate or restore a prior snapshot.

Collection reads the selected tables from a connected system and loads the result into the Vault. Collect after changing a system connection or data model, and before workflows need current identity data.

Collect before building on the dataFilters, mappings, roles, and relation validation depend on the data currently loaded in the Vault. Run and review a collection before relying on a new or changed configuration.

Collect and validate current data

Collect a system

1. Open Systems > Overview.
2. Select Collect for the system.
3. Watch the system status while NIM collects the selected tables.
4. When the status changes to success, review the returned messages in the Log pane.

Outcome: the collected tables are loaded into the Vault and ready for review.

View the latest system collection

1. Open Systems > Overview.
2. Select View Latest Collection Log for the system.
3. Review the collection result in the Log pane, including warnings or errors that may affect data quality.

Check: confirm that expected tables completed and that no unexpected errors or warnings require attention.

View latest table collection

1. Expand the system’s table list and open the table to inspect.
2. Select the Data tab.
3. Review the current rows in the Table Data pane.
4. If needed, export the data pane to CSV for additional review.

Check: verify the expected records, values, and relationships are present before using the data in filters or mappings.

Step 1 of 3

Work with collection history

Every collection creates a timestamped snapshot. Use the history to compare a past result, temporarily load a known collection into the Vault, or remove a snapshot that is no longer needed.

View past system collections

1. Open Systems > Overview.
2. Select View System Collection History for the system.
3. Select a past collection, then choose View Collection Log to review its result.

To inspect data from a specific historical table collection, open that table, select Collection History, and choose View Collection History.

View past table collections

The selected historical table data appears in the Table Data pane. Use it to compare a prior snapshot with the data currently loaded in the Vault.

Load a past system collection

1. Open View System Collection History for the relevant system.
2. Identify the snapshot you want to use and review its log first.
3. Select Load Collection for that snapshot.
4. Confirm Yes to load its data into the Vault.

Outcome: NIM loads the selected snapshot into the Vault without making a new request to the source system.

warning

Loading a past collection changes the data currently available to downstream filters, mappings, and roles. Confirm the snapshot and test dependent workflows before running a job.

Remove a past system collection

1. Open View System Collection History for the relevant system.
2. Confirm that the snapshot is no longer needed for troubleshooting, comparison, or restoration.
3. Select Remove Collection for the snapshot.
4. Confirm Yes.

danger

Removing a collection permanently deletes that snapshot and its data. Export or document anything you need before confirming removal.

• Review Dataset statistics when you need deeper collection validation metrics.
• Configure collection guards to stop unexpected source changes before they affect downstream work.
• Use filters to select and shape the current Vault data for your workflows.
