Grok Patterns
Use the built-in library of Grok patterns, or define your own.
A Grok pattern is a string of special characters and regular expressions that match data. Cribl Search uses Grok patterns in definitions for Parsers.
Cribl Search ships with many commonly used Grok patterns. The Grok Patterns page provides an interface for creating and editing them.
