Manage Field Extractions

Field Extractions allow you to parse fields from your log messages at the time the messages are ingested, which eliminates the need to parse fields at the query level. With Field Extraction Rules in place, users can use the parsed fields for ad-hoc searches, Scheduled Searches, Real Time Alerts and Dashboards. In addition, Field Extraction Rules help standardize field names and searches, simplify the search syntax and scope definition, and improve search performance. 

Note that fields are extracted from the time your create your FER moving forward. Therefore, set your FERs early on to take advantage of of this automatic parsing mechanism.
