💡 Usage Example

from core.analytics import MetricsCollector, ResourceCollector, TimeSeriesStore
from pathlib import Path

# Initialize storage
store = TimeSeriesStore(Path('data/analytics'))

# Initialize collectors
metrics_collector = MetricsCollector(
    storage_callback=store.write_metrics,
    buffer_size=1000,
    flush_interval_sec=5.0
)

resource_collector = ResourceCollector(
    storage_callback=store.write_metrics,
    sample_interval_sec=1.0
)

# Start collectors
metrics_collector.start()
resource_collector.start()

# Record execution
metrics_collector.record_execution_start('exec_123', 'workflow_abc')

# Set resource context
resource_collector.set_context('workflow_abc', 'exec_123')

# ... workflow executes ...

# Record completion
metrics_collector.record_execution_complete(
    'exec_123',
    status='completed',
    steps_total=10,
    steps_completed=10,
    steps_failed=0
)

# Query metrics
from datetime import datetime, timedelta
end_time = datetime.now()
start_time = end_time - timedelta(hours=1)

metrics = store.query_range(
    start_time=start_time,
    end_time=end_time,
    workflow_id='workflow_abc'
)

print(f"Executions: {len(metrics['execution'])}")
print(f"Steps: {len(metrics['step'])}")
print(f"Resource samples: {len(metrics['resource'])}")

# Aggregate
avg_duration = store.aggregate(
    metric='duration_ms',
    aggregation='avg',
    group_by=['workflow_id'],
    start_time=start_time,
    end_time=end_time
)

🎓 Architecture Highlights

Async Collection

• Metrics are buffered in memory
• Flushed asynchronously every 5 seconds
• No blocking of workflow execution
• Thread-safe operations

Time-Series Optimization

• Indexes on time fields for fast queries
• Separate tables for different metric types
• Support for time-range queries
• Aggregation at database level

Resource Tracking

• Background thread for periodic sampling
• Context-aware (knows which workflow is running)
• Optional GPU monitoring
• Minimal overhead

🔧 Configuration

MetricsCollector

MetricsCollector(
    storage_callback=callback,  # Function to persist metrics
    buffer_size=1000,           # Max buffer before force flush
    flush_interval_sec=5.0      # Auto-flush interval
)

ResourceCollector

ResourceCollector(
    storage_callback=callback,  # Function to persist metrics
    sample_interval_sec=1.0     # Sampling interval
)

TimeSeriesStore

TimeSeriesStore(
    storage_path=Path('data/analytics')  # Storage directory
)

✨ Ready for Integration

Le système de collection et stockage est prêt à être intégré avec l'ExecutionLoop existant !

Pour continuer l'implémentation, ouvre .kiro/specs/rpa-analytics/tasks.md et commence par la Task 3 !
