# Logging Migrator Skill

Migrates logging infrastructure, handling log format standardization, structured logging conversion, and aggregation setup.

## Purpose

Enable logging modernization for:
- Log format standardization
- Structured logging conversion
- Log aggregation setup
- Correlation ID injection
- Retention policy migration

## Capabilities

### 1. Log Format Standardization
- Define standard format
- Convert existing logs
- Implement across services
- Validate compliance

### 2. Structured Logging Conversion
- Convert to JSON format
- Add metadata fields
- Handle custom fields
- Support multiple languages

### 3. Log Aggregation Setup
- Configure centralized logging
- Set up log shipping
- Handle high volume
- Implement failover

### 4. Correlation ID Injection
- Implement trace IDs
- Propagate across services
- Handle async operations
- Enable distributed tracing

### 5. Log Level Normalization
- Standardize log levels
- Map between frameworks
- Configure filtering
- Handle verbosity

### 6. Retention Policy Migration
- Define retention rules
- Implement rotation
- Handle archival
- Manage storage

|------|---------|-------------------|
| ELK Stack | Log aggregation | Config |
| Datadog | Observability | API |
