AlertThresholdAlgo

API reference for AlertThresholdAlgo

AlertThresholdAlgo

Threshold determination algorithms for alert rules.

Defines how alert thresholds are calculated - either manually specified or automatically computed based on historical data patterns.

MANUAL

User-specified static thresholds. Provides full control but requires domain knowledge to set appropriately.

STD_DEV_AUTO_THRESHOLD

Automatic thresholds based on standard deviation. Calculates thresholds as mean ± (multiplier × std_dev) from historical data. Adapts to data patterns automatically.

Example

# Manual threshold - user knows the acceptable drift limit
manual_alert = AlertRule(
    threshold_type=AlertThresholdAlgo.MANUAL,
    critical_threshold=0.1,
    warning_threshold=0.05
)

# Auto threshold - let system learn from historical patterns
auto_alert = AlertRule(
    threshold_type=AlertThresholdAlgo.STD_DEV_AUTO_THRESHOLD,
    auto_threshold_params={
        'warning_multiplier': 2.0,  # 2 std devs for warning
        'critical_multiplier': 3.0  # 3 std devs for critical
    }
)

#### MANUAL *= 'manual'*

#### STD_DEV_AUTO_THRESHOLD *= 'standard_deviation_auto_threshold'*

#### \_\_str_\_()

Return the string value of the enum.

#### Returns
The enum’s string value for serialization and display.
**Return type:** str

#### Example
```python
>>> algo = AlertThresholdAlgo.MANUAL
>>> str(algo)
'manual'
