## Overview

Build comprehensive log aggregation systems to collect, parse, and analyze logs from multiple sources, enabling centralized monitoring, debugging, and compliance auditing.

## When to Use

- Centralized log collection
- Distributed system debugging
- Compliance and audit logging
- Security event monitoring
- Application performance analysis
- Error tracking and alerting
- Historical log retention
- Real-time log searching

## Quick Start

Minimal working example:

```yaml
# docker-compose.yml - ELK Stack setup
version: "3.8"

services:
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:8.5.0
    environment:
      - discovery.type=single-node
      - xpack.security.enabled=false
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ports:
      - "9200:9200"
    volumes:
      - elasticsearch_data:/usr/share/elasticsearch/data
    healthcheck:
      test: curl -s http://localhost:9200 >/dev/null || exit 1
      interval: 10s
      timeout: 5s
      retries: 5

  logstash:
    image: docker.elastic.co/logstash/logstash:8.5.0
    volumes:
      - ./logstash.conf:/usr/share/logstash/pipeline/logstash.conf
    ports:
// ... (see reference guides for full implementation)
```

## Best Practices

### ✅ DO

- Parse and structure log data
- Use appropriate log levels
- Add contextual information
- Implement log retention policies
- Set up log-based alerting
- Index important fields
- Use consistent timestamp formats
- Implement access controls

### ❌ DON'T

- Store sensitive data in logs
- Log at DEBUG level in production
- Send raw unstructured logs
- Ignore storage costs
- Skip log parsing
- Lack monitoring of log systems
- Store logs forever
- Log PII without encryption
