What's New in v1.12.14.6

Multi-Output Logging System

This release introduces a comprehensive multi-output logging system with structured event support:

Core Features:

• Multi-Output Support: Send logs to multiple destinations simultaneously (HTTP, file, stdout, stderr)
• JSON Formatting: Structured JSON logs with full metadata capture
• HTTP Batch Output: Batch POST logs to remote collectors with JWT authentication
• Structured Events: Rich event data for connections, DNS queries, routing matches, and transfers
• Backward Compatible: Legacy single-output configurations continue to work

Structured Logging:

• ConnectionEvent: Connection lifecycle with source/destination details
• DNSEvent: DNS queries with resolution info
• RouterMatchEvent: Routing decisions and rule matches
• TransferEvent: Data transfer statistics

Configuration Example:

{
  "log": {
    "level": "info",
    "outputs": [
      {
        "type": "stdout",
        "format": "formatted",
        "timestamp": true
      },
      {
        "type": "http",
        "format": "json",
        "url": "http://log-collector:8080/logs",
        "jwt_token": "eyJhbGc...",
        "batch_size": 100,
        "flush_interval": "5s",
        "hostname": "proxy-01"
      }
    ]
  }
}
