Field Extractor: Validate step

The Validate step of the field extractor is for regular-expression-based field extractions only.

Validate your field extraction in the Validate step of the field extractor. The field extractor provides the following validation methods:

When you are done validating your field extractions, click Save to save the extraction.

Provide counterexample feedback

This is an optional action for the Validate step.

If you find events that contain incorrectly extracted fields, submit those events as counterexample feedback.

1. Find an event with a field value that has been incorrectly extracted.

The highlighted text is not a correct value for the field that the highlighter represents.

2. Click the gray "X" next to the incorrect field value.

The field extractor displays the counterexample event above the table, marking the incorrect value with red strikethrough. It also updates the regular expression and its preview results.
