Alert trigger conditions for metric comparisons. Defines the comparison operator used to evaluate whether an alert should trigger based on the metric value and threshold.

​
GREATER

Trigger when metric value > threshold. Common for drift detection, error rates, latency spikes.

​
LESSER

Trigger when metric value < threshold. Common for accuracy drops, traffic decreases, availability issues.

​
Example

# Alert when data drift exceeds 5%
drift_alert = AlertRule(
        condition=AlertCondition.GREATER,
        threshold=0.05
    )

    # Alert when model accuracy drops below 90%
    accuracy_alert = AlertRule(
            condition=AlertCondition.LESSER,
            threshold=0.90
        )

​
GREATER = ‘greater’

​
LESSER = ‘lesser’
