## What it is
Monolog is the de facto standard logging library for PHP, implementing the PSR-3 logger interface. It sends logs to files, sockets, databases, and web services via a flexible system of handlers, formatters, and processors.

## Use cases
- log application errors to files in PHP
- send PHP logs to Slack or email
- implement PSR-3 compatible logging in a library
- route logs to multiple destinations with different severity levels
- structure and format log records for log aggregation services

## When to choose
- you need logging in any PHP application or framework
- you want PSR-3 interoperability so you can swap loggers later
- you need to fan out logs to many backends like files, sockets, and web services

## When to avoid
- you are not working in PHP
- you need a full log aggregation and visualization platform rather than a logging library

## Facets
- artifact type: library
- maturity: stable
- function: logging
- domain: developer-tools, backend, monitoring
- platform: php
- tags: psr-3, log-handlers, composer
