# Get Engine Performance

> Get engine performance metrics over time.

Query profiling data logged by the engine's profiling infrastructure.
All queries are automatically filtered to your namespace.

**Time Range:**
- Specify `hours` for recent history (e.g., `hours=24` for last 24 hours)
- OR specify `start_date` and `end_date` for custom range
- Defaults to last 24 hours if neither provided

**Grouping:**
- `minute`: High-resolution (for short time ranges)
- `hour`: Standard resolution (default)
- `day`: For longer time ranges
- `week`, `month`: For historical trends

**Response:**
- Time-series metrics (avg, p50, p95, p99 latencies)
- Summary statistics across the entire time range
- All latencies in milliseconds

**Example:**
```bash
GET /v1/analytics/performance/engine?hours=24&group_by=hour
```
