Adaptive Alerts is a feature from Rollbar designed to enhance alerting about unexpected issues in monitored applications by employing anomaly detection to learn baseline error rates and notifying developers when these rates become atypical. This feature aims to address the problem of noise from fixed error threshold alerts, which burden developers with unnecessary notifications. Compared to previous alerting methods like the 10^nth Occurrence and High Occurrence Rate, Adaptive Alerts significantly reduces notifications by 86% through dynamically adjusting thresholds and providing a broader exception-level view to detect trends. It continuously trains on historical data to establish baselines and sends alerts within minutes of detecting significant anomalies, allowing users to customize sensitivity and alert thresholds. Available to Advanced and Enterprise plan customers, Adaptive Alerts has been praised by industry professionals for effectively grouping errors and improving alert accuracy.
