For a high error rate in a Lambda function, how many one-minute intervals are considered for raising an alert?

For raising an alert based on a high error rate in a Lambda function, the threshold is designed to account for fluctuations in error rates over a specific timeframe. By evaluating 3 of the 5 one-minute intervals, the system ensures that temporary spikes or anomalies do not trigger alerts unnecessarily. This method provides a balance between being responsive to legitimate issues while avoiding alerts for transient problems that may resolve themselves quickly.

By requiring 3 out of 5 intervals to show a high error rate, the system effectively confirms that the error condition is persistent and not just an outlier or momentary issue. This approach helps maintain alerting accuracy and minimizes alert fatigue among operators, ensuring that only significant and actionable issues are brought to their attention.
