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’

str()

Return the string value of the enum.

Returns
