## What it is
syslog-ng is an enhanced syslog daemon that collects, parses, filters, and routes log messages from a wide range of sources including syslog, unstructured text, JSON, message queues, and databases. It supports forwarding logs to destinations such as files, SQL/NoSQL databases, Elasticsearch, Kafka, and Hadoop.

## Use cases
- centralize syslog messages from multiple servers
- parse and structure unstructured log data
- forward logs to elasticsearch or kafka
- collect system logs and write them to a file
- route application logs to a database
- filter and normalize logs in transit

## When to choose
- you need a high-performance, configurable syslog daemon
- you must route logs to many different destinations like databases, queues, or big-data tools
- you need to parse and classify logs on the fly with built-in parsers

## When to avoid
- you only need a minimal syslog daemon with simple file output
- you prefer a lightweight agent-based log shipper like fluent-bit or vector
- you need a fully managed cloud logging service
