The new Lookup Examples Pack aims to address the common hurdles of data enrichment by providing examples that demonstrate how to leverage the powerful lookup capabilities within the Cribl product suite.
Test Drive
The Lookup Examples Pack features twenty diverse lookup examples, including three utilizing the Code Function for enhanced versatility in your data enrichment journey. To begin, simply install the Pack from Cribl’s Pack Dispensary. Once installed, access the Lookup Examples Pack, open the Lookup_Examples Pipeline, and explore the corresponding Lookup_Event.log sample. Toggle each of the Pipeline Groups one at a time and save your changes. Check the results in the Simple Preview, which also includes an “_explanation” field at the top. Here are a few examples:
Lookup Function Example
This Pipeline Group utilizes the ‘kv.csv‘ lookup table to look for an exact match of KEY1. If it finds a match in the first column, it retrieves the other columns from the matched row by default.
C.Lookup Expression Example
In this Pipeline Group, KEY1 represents the column in the ‘kv.csv‘ lookup table that serves as the key column. The brackets [] means return all columns from which you want to retrieve the value when a match is found.
Code Function Example
In this Pipeline Group, the Code Function is used to map KEY1 to match the expected format and perform a lookup in the ‘kv.csv‘ lookup table. The green comments in the Code Function provide additional detail.
