## What it is
Lograge is a Ruby gem that replaces Rails' default multi-line request logging with a single, parsable key-value line per request. It is designed for production Rails applications where noisy, unparsable logs make debugging and log aggregation difficult.

## Use cases
- reduce noisy Rails request logs to one line per request
- make Rails logs parsable by log aggregation tools like Splunk or ELK
- add custom key-value fields to Rails request logs
- clean up production logging across multiple app servers
- log request duration, controller, status, and database time in structured format

## When to choose
- you run Rails in production and need clean, machine-parsable logs
- you aggregate logs from multiple processes and Rails' default output is unreadable
- you want structured key-value logging without switching logging frameworks

## When to avoid
- you are in early development and benefit from Rails' verbose default output
- you don't use Rails or a compatible framework
- you need timestamps included by default (you must configure a log formatter)

## Facets
- artifact type: library
- maturity: active
- function: logging, middleware
- domain: web-development, backend, monitoring, developer-tools
- platform: ruby, cross-platform
- tags: rails, structured-logging, log-formatting, key-value-logs, production-logging, web-server
