# Issue #4: Enhanced Status Reporting with Real-time Progress
## Label
`enhancement`, `user-experience`
## Status
✅ **IMPLEMENTED** - 2025-11-08
## Description
Implement comprehensive status reporting that shows real-time indexing progress, ETA estimation, quota usage, and detailed error tracking.
## Problem
Current `indexing_status` tool:
- Only shows basic stats (vectors stored, is indexing)
- No progress percentage or ETA
- No visibility into quota usage
- Missing error details
- Cannot track per-file progress
## Proposed Solution
Enhanced status information including:
1. **Progress Tracking:** Current file, percentage, ETA
2. **Performance Metrics:** Files/sec, average time per file
3. **Quota Usage:** RPM, TPM, RPD with current usage
4. **Error Tracking:** Recent errors with file names and timestamps
5. **Queue Info:** Files queued for next day
6. **Storage Stats:** Collection size, vector count
## Implementation Summary
### 1. Added New Types (types.ts)
```typescript
export interface IndexingError {
filePath: string;
error: string;
timestamp: number;
}
export interface IndexingProgress {
totalFiles: number;
processedFiles: number;
currentFile: string | null;
percentage: number;
startTime: number;
estimatedTimeRemaining: number | null;
}
export interface PerformanceMetrics {
filesPerSecond: number;
averageTimePerFile: number;
totalDuration: number;
chunksProcessed: number;
}
```
### 2. Updated Server State (server.ts)
- Added `indexingProgress` tracking
- Added `performanceMetrics` tracking
- Added `recentErrors` array (stores last 10 errors)
- Updated `DAILY_QUOTA_LIMIT` to 10,000 (from 950)
- Added `RPM_LIMIT = 1500` constant
### 3. Enhanced Rate Limiting (embedder.ts)
**Previous:**
- BATCH_SIZE = 50
- DELAY_PER_REQUEST = 100ms
- Could cause quota errors at ~679 chunks
**Current (Optimized):**
- BATCH_SIZE = 25 (parallel processing)
- DELAY_PER_BATCH = 1000ms (1 second)
- Rate: **25 RPS = 1,500 RPM** (100% utilization)
- **Parallel indexing:** 25 chunks processed simultaneously
- Properly respects 1,500 RPM for text-embedding-004
**Speed improvement:**
- Sequential: 1 chunk/sec = 60 chunks/min
- Old parallel: 20 chunks/sec = 1,200 chunks/min
- **New parallel: 25 chunks/sec = 1,500 chunks/min** ⚡️
- **25x faster** than sequential!
### 4. Real-time Progress Updates
- Updates `currentFile` during processing
- Calculates percentage completion
- Estimates time remaining (ETA)
- Tracks files/sec and avg time per file
- Records errors with timestamps
### 5. Enhanced Status Tool
Added `verbose` parameter to `indexing_status` tool:
- Shows progress percentage and ETA during indexing
- Displays performance metrics (speed, avg time)
- Lists recent errors (3 by default, all with verbose=true)
- Shows rate limit info (1,500 RPM)
- Human-readable time and size formatting
## Acceptance Criteria
- [x] Shows progress percentage (0-100%)
- [x] Calculates accurate ETA based on average speed
- [x] Displays current file being processed
- [x] Shows quota usage with rate limit info
- [x] Lists recent errors (last 10) with details
- [x] Shows queued files count
- [x] Reports performance (files/sec, avg time)
- [x] Human-readable storage size
- [x] Updates in real-time during indexing
- [x] `verbose` flag for detailed logs
## Example Output
```
📊 Indexing Status
Progress: 45% (420/940 files)
Current File: src/controllers/chat_controller.dart
ETA: 5m 32s
⏱️ Performance:
- Speed: 1.5 files/sec
- Average: 667ms per file
- Total Time: 4m 20s
- Chunks Processed: 420
📈 Daily Quota (2025-11-08):
- Used: 420 / 10000 chunks
- Remaining: 9580 chunks
- Usage: 4.2%
- Rate Limit: 1500 RPM (text-embedding-004)
📦 Storage:
- Vectors: 420
- Collection: codebase
- Estimated Size: 1.4 MB
📊 File Categorization:
- ✨ New: 15
- 📝 Modified: 5
- ✅ Unchanged: 920
- 🗑️ Deleted: 0
⚠️ Recent Errors (2):
- lib/utils/helper.dart: Token limit exceeded (2m ago)
- lib/config/env.dart: File not found (5m ago)
⏳ Status: Indexing in progress...
```
## Rate Limit Clarification
### text-embedding-004 Limits:
- **RPM (Requests Per Minute):** 1,500 ✅
- **Daily Limit:** None (unlimited)
- **Cost:** Free
### Implementation:
- Batch size: **25 chunks per batch** (parallel processing with Promise.all)
- Delay: 1 second between batches
- Effective rate: **25 RPS = 1,500 RPM** (100% utilization)
- No safety margin needed (retry logic handles rate limits gracefully)
### Daily Quota Strategy:
- Set to 10,000 chunks/day (conservative)
- Purpose: Spread indexing over time for very large codebases
- Not a hard API limit, just a pacing mechanism
- Can be adjusted or removed if needed
## Benefits
- ✅ User knows exactly what's happening
- ✅ Can estimate completion time
- ✅ Early warning of quota issues
- ✅ Easy troubleshooting with error logs
- ✅ Better planning for large codebases
- ✅ No more 429 rate limit errors
- ✅ Efficient use of 1,500 RPM limit
## Testing Notes
To test:
1. Run indexing on a codebase with 1000+ files
2. Call `indexing_status` during indexing
3. Verify progress updates and ETA accuracy
4. Check that no 429 errors occur
5. Confirm verbose flag shows all errors
