This may be because the stream has not been started yet or the stream ID is invalid. -``` - -### Authentication Failure - -**HTTP 401 Unauthorized** -```json -{ - "error": "Authentication failed" -} -``` - -### Permission Denied - -**HTTP 403 Forbidden** -```json -{ - "error": "Access denied: Admin privileges required" -} -``` - -## Use Cases - -### Development and Debugging - -Use the HTTP endpoint to quickly check recent log entries: -```bash -# Get last 50 lines -curl "...?tail=50" -``` - -### Long-term Analysis - -Download the entire log for offline analysis: -```bash -# Download complete log -curl "...?download=true" -o stream-logs.log -``` - -### Real-time Monitoring - -Use WebSocket for live monitoring of active streams: -```javascript -// Monitor multiple streams simultaneously -const streams = ['stream-id-1', 'stream-id-2', 'stream-id-3']; -streams.forEach(streamId => { - const ws = new WebSocket(`wss://api.example.com/api/v1/admin/pipeline-log/${streamId}`); - ws.onmessage = (event) => { - console.log(`[${streamId}]`, event.data); - }; -}); -``` - -## Implementation Notes - -- Log files are stored in `{output_dir}/{stream_id}/pipeline.log` -- The WebSocket implementation uses tokio's async file reading with buffering -- Log lines are sent to WebSocket clients as they are written (100ms polling interval) -- The endpoint is designed to handle large log files efficiently by reading only the necessary tail portion
