Grok Patterns Library

What Is the Grok Patterns Library

​

Cribl Edge ships with a Grok Patterns Library that contains a set of pre-built common patterns, organized as files.

Managing Library Patterns

​

You can access the Grok Patterns Library by selecting Fleets from the sidebar and choosing a Fleet. Then, on the Fleets submenu, select More, then Knowledge, then Grok Patterns. The library contains several pattern files that Cribl provides for basic Grok scenarios, and is searchable.

To create a new pattern file, select Add Grok Pattern File. In the resulting modal, assign a unique File name, populate the file with patterns, then select Save.

Pattern files reside in: $CRIBL_HOME/(default|local)/cribl/grok-patterns/

Using Grok Patterns

​

In the current Cribl Edge version, you apply Grok patterns by inserting a Grok Function into a Pipeline, then manually typing or pasting patterns into the Pattern field(s).
