The Apache NiFi framework stores information about FlowFiles as they move through your ingestion pipeline. You can use the "Data Provenance" feature to see what happened to a document.
To configure searching by IDOL document reference or identifier
./conf/nifi.properties
. Set or review the following properties:
nifi.provenance.repository.indexed.attributes
Set this property to idol.reference, idol.doc.identifier
so that you can search for documents by their IDOL document reference or identifier.
To track a document
Click followed by Data Provenance.
The NiFi Data Provenance dialog box opens.
Type a document reference (in the idol.reference box) or identifier (in the idol.doc.identifier box) and click SEARCH.
NOTE: Type the exact reference or identifier. Alternatively, you can use the *
wildcard to represent any number of characters. However, if you use the *
wildcard, the backslash character (\
) becomes a special character and must be escaped. For example:
C:\Some\Path\document.txt
- (a wildcard is not used)C:\\Some\\Path\\*
- (a wildcard is used , so escape the backslashes in the path. This matches all references that start with C:\Some\Path\
)If the value you want to search for includes a literal asterisk (*
), escape the asterisk with a backslash (\
).
The NiFi Data Provenance dialog box displays events related to the selected document(s).
For more information about data provenance features, refer to the Apache NiFi documentation.
