# Event Emission Console - Implementation Complete
**Date**: October 16, 2025
**Status**: ✅ IMPLEMENTED & DEPLOYED
## Summary
Successfully extended the MCP Control Center with a comprehensive Event Emission Console that displays real-time events from the Hammerspace MCP server, including the new PDF ingest workflow events.
## What Was Implemented
### 1. Enhanced File Monitor (`src/inotify_monitor.py`)
**New Event Logging Features:**
- ✅ **PDF Ingest Success Events**: Logs when PDF ingest jobs are successfully created and deployed
- ✅ **PDF Ingest Failure Events**: Logs when PDF ingest job creation/deployment fails
- ✅ **Event Emission**: All events are written to the JSON log file for the Event Console
- ✅ **Return Status**: Methods now return success/failure status for proper event tracking
**New Methods Added:**
- `emit_pdf_ingest_event(file_path, success)` - Emits PDF ingest events to the log
- Enhanced `trigger_pdf_ingest_job()` - Returns success/failure status
- Enhanced `create_pdf_ingest_job()` - Returns success/failure status
### 2. Event Console Web Interface (`web_ui/templates/events.html`)
**Features:**
- ✅ **Real-time Event Display**: Shows all events from the MCP server
- ✅ **Event Filtering**: Filter by event type, file path, and other criteria
- ✅ **Auto-refresh**: Automatically refreshes every 5 seconds
- ✅ **Event Statistics**: Shows counts of different event types
- ✅ **Responsive Design**: Works on desktop and mobile devices
- ✅ **Event Details**: Displays comprehensive event information
**Event Types Supported:**
- `NEW_FILE` - New files detected and tagged
- `RETROACTIVE_TAG` - Existing files tagged retroactively
- `PDF_INGEST_SUCCESS` - PDF ingest jobs successfully created
- `PDF_INGEST_FAILURE` - PDF ingest jobs failed to create
### 3. Web UI Integration (`web_ui/app.py`)
**New Routes:**
- ✅ `/events` - Event Console page
- ✅ `/api/events` - API endpoint for event data
**API Features:**
- ✅ **Event Retrieval**: Gets events from the inotify.log file
- ✅ **Filtering**: Supports event type and file path filtering
- ✅ **Pagination**: Limits results (default 1000 events)
- ✅ **JSON Parsing**: Properly parses JSON events from log file
- ✅ **Error Handling**: Comprehensive error handling and logging
### 4. Navigation Integration (`web_ui/templates/index.html`)
**New Button:**
- ✅ **📡 Events Button**: Added to the main navigation bar
- ✅ **Styling**: Green color scheme to distinguish from other buttons
- ✅ **Integration**: Seamlessly integrated with existing Monitor and Debug buttons
## Current Status
### ✅ Working Components:
- **Event Console Page**: Fully functional and accessible at `/events`
- **API Endpoint**: Successfully serving event data
- **Event Logging**: PDF ingest events are being logged
- **File Monitor**: Enhanced with event emission capabilities
- **Navigation**: Events button added to main interface
### 📊 Event Data Available:
- **Total Events**: 569+ events currently in the system
- **Event Types**: NEW_FILE, RETROACTIVE_TAG, PDF_INGEST_SUCCESS, PDF_INGEST_FAILURE
- **Real-time Updates**: Events are logged as they occur
- **Historical Data**: All past events are preserved and accessible
## How to Use
### Accessing the Event Console:
1. **Main Interface**: Click the "📡 Events" button on the main page
2. **Direct URL**: Navigate to `http://localhost:5000/events`
3. **API Access**: Use `http://localhost:5000/api/events` for programmatic access
### Event Console Features:
- **Filter Events**: Use the dropdown to filter by event type
- **Search Files**: Use the file path filter to find specific files
- **Auto-refresh**: Toggle automatic refresh on/off
- **Manual Refresh**: Click refresh button for immediate updates
- **Clear Events**: Clear the display (doesn't delete from log)
- **Copy Data**: Copy individual event data or file paths
### Event Types Explained:
- **NEW_FILE**: Files newly detected by the file monitor
- **RETROACTIVE_TAG**: Existing files that were tagged when the monitor started
- **PDF_INGEST_SUCCESS**: PDF files that successfully triggered ingest jobs
- **PDF_INGEST_FAILURE**: PDF files that failed to trigger ingest jobs
## Technical Details
### Event Data Structure:
```json
{
"timestamp": "2025-10-16T02:21:08.209822",
"event_type": "PDF_INGEST_SUCCESS",
"file_name": "document.pdf",
"file_path": "/mnt/anvil/hub/document.pdf",
"status": "SUCCESS",
"job_type": "pdf_ingest",
"collection_name": "bulk_selected_pdfs",
"ingest_time": "2025-10-16T02:21:08.209822"
}
```
### API Parameters:
- `limit`: Number of events to return (default: 1000)
- `event_type`: Filter by specific event type
- `file_pattern`: Filter by file path pattern
### Log File Location:
- **Path**: `/home/ubuntu/mcp-1.5-main/logs/inotify.log`
- **Format**: JSON lines (one event per line)
- **Rotation**: Managed by the file monitor service
## Integration with PDF Ingest Workflow
The Event Console now provides complete visibility into the PDF ingest workflow:
1. **File Detection**: See when PDF files are detected in `/mnt/anvil/hub`
2. **Job Creation**: Monitor PDF ingest job creation success/failure
3. **Error Tracking**: Identify and troubleshoot failed ingest jobs
4. **Performance Monitoring**: Track the volume and timing of ingest operations
## Files Created/Modified
### New Files:
- `web_ui/templates/events.html` - Event Console interface
- `EVENT_CONSOLE_SUMMARY.md` - This documentation
### Modified Files:
- `src/inotify_monitor.py` - Enhanced with event emission
- `web_ui/app.py` - Added `/events` route and `/api/events` endpoint
- `web_ui/templates/index.html` - Added Events navigation button
## Next Steps
1. **Monitor Usage**: Watch the Event Console for PDF ingest events
2. **Test Workflow**: Drop PDF files into `/mnt/anvil/hub` to see events
3. **Troubleshoot**: Use the console to debug any ingest job issues
4. **Optimize**: Monitor event volume and adjust filtering as needed
The Event Emission Console is now fully operational and provides comprehensive visibility into all MCP server activities! 🎉
