Error Rate
The percentage of requests that result in error responses (HTTP 4xx or 5xx, gRPC non-OK status) over a given time window, expressed as error_count / total_requests × 100. Error rate is a primary Service Level Indicator (SLI) for API reliability and a key input to SLO budget calculations. Sudden spikes in error rate trigger alerts and circuit breaker thresholds. Distinguishing client errors (4xx) from server errors (5xx) is important when diagnosing the source of reliability degradation.
