Error Rate Metrics
Error rate metrics are quantitative measures used to assess the frequency or proportion of errors in a system, process, or software application. They are commonly expressed as percentages or ratios, such as the number of errors per total transactions or requests. These metrics help in monitoring reliability, performance, and quality by tracking failures like bugs, crashes, or incorrect outputs.
Developers should learn and use error rate metrics to identify and prioritize issues in software systems, enabling proactive debugging and performance optimization. They are essential in DevOps and SRE practices for setting service-level objectives (SLOs) and ensuring high availability, particularly in web applications, APIs, and distributed systems where uptime is critical.
