Log Parser

Definitions

1. A tool or library that extracts structured data from raw log lines — parsing timestamps, severity levels, request IDs, and other fields from unstructured text using patterns like regex, grok, or delimiter-based rules. Often a component of a log aggregation pipeline.

   In plain English: A tool that reads messy log files and pulls out useful structured information like timestamps, error codes, and request details.

   Example: "The log parser uses a grok pattern to extract the status code and response time from each Nginx access log line into searchable fields."
