## Key Features

### 1. Webhook-Based Alert Notifications

```python
# Register webhook
register_alert_webhook(
    AlertType.HIGH_LATENCY,
    "https://hooks.slack.com/services/YOUR/WEBHOOK",
)

# Send alert
result = await send_alert(
    alert_type=AlertType.HIGH_LATENCY,
    message="High latency detected",
    severity=AlertSeverity.WARNING,
)
```

### 2. Pattern Detection Thresholds

```python
# Configure custom threshold
configure_alert_threshold(AlertType.HIGH_LATENCY, 2000.0)

# Check metric and alert if exceeded
result = await check_metric_and_alert(
    alert_type=AlertType.HIGH_LATENCY,
    value=1500.0,
    metadata={"service": "api-gateway"},
)
```

### 3. Alert Deduplication

- **Window**: 5 minutes (configurable)
- **Key**: `{alert_type}:{hash(pattern_data)}`
- **Cleanup**: Automatic removal of old entries

### 4. Multiple Alert Types

Anomaly Detection:
- ANOMALY_DETECTED (threshold: 2.0σ)
- SPIKE_IN_ERRORS (threshold: 10x)
- UNUSUAL_TRAFFIC

System Health:
- HIGH_LATENCY (threshold: 1000ms)
- LOW_HIT_RATE (threshold: 50%)
- STORAGE_CAPACITY

Trend Analysis:
- TREND_CHANGE
- PREDICTION_THRESHOLD

Knowledge Graph:
- NEW_ENTITY_DETECTED
- RELATIONSHIP_CHANGE

## Integration Points

### With Akosha Analytics

```python
# In analytics pipeline
async def monitor_system_health(metrics):
    # Check latency
    await check_metric_and_alert(
        AlertType.HIGH_LATENCY,
        metrics["latency_ms"],
        metadata={"service": metrics["service"]},
    )

    # Check hit rate
    await check_metric_and_alert(
        AlertType.LOW_HIT_RATE,
        metrics["hit_rate"],
        metadata={"cache": metrics["cache_name"]},
    )
```

### With Oneiric Caching

```python
# Monitor cache performance
async def monitor_cache_performance(cache_metrics):
    # Alert on low hit rate
    await check_metric_and_alert(
        AlertType.LOW_HIT_RATE,
        cache_metrics["hit_rate"],
        metadata={"adapter": cache_metrics["adapter_name"]},
    )
```

### With Session-Buddy

```python
# Alert on memory anomalies
async def monitor_memory_anomalies(anomaly_score):
    await check_metric_and_alert(
        AlertType.ANOMALY_DETECTED,
        anomaly_score,
        metadata={"component": "memory-aggregation"},
    )
```

## Technical Implementation Details

### Alert Format

```json
{
  "id": "550e8400-e29b-41d4-a716-446655440000",
  "alert_type": "high_latency",
  "severity": "warning",
  "message": "High latency detected: 1500.00ms (threshold: 1000.00ms)",
  "metadata": {
    "service": "api-gateway",
    "region": "us-east-1"
  },
  "timestamp": "2026-02-05T10:30:00Z",
  "pattern_data": {
    "threshold": 1000.0,
    "actual_value": 1500.0
  }
}
```

### Deduplication Logic

```python
# Create deduplication key
key = f"{alert.alert_type.value}:{hash(str(alert.pattern_data))}"

# Check if recently sent
if key in self._sent_alerts:
    last_sent = self._sent_alerts[key]
    age = (datetime.now(UTC) - last_sent).total_seconds()

    # Skip if sent within deduplication window
    if age < self.window_minutes * 60:
        return False

# Mark as sent
self._sent_alerts[key] = datetime.now(UTC)
```

### Threshold Checking

```python
# Check if threshold exceeded
triggered = value > threshold if alert_type != AlertType.LOW_HIT_RATE else value < threshold

if triggered:
    return Alert(
        alert_type=alert_type,
        severity=self._get_severity(alert_type),
        message=self._format_message(alert_type, value, threshold),
        metadata=metadata or {},
        pattern_data={"threshold": threshold, "actual_value": value},
    )
```
