Conclusion

Health rate calculation offers a single measurement that reflects overall system health, enabling analysts to detect high-level problems at a glance.

By reversing health rate calculations, analysts can readily determine if errors are availability problems, accuracy problems, or performance problems. Ultimately, analysts can drill down to the relevant measurement data that is responsible for specific errors.

Health rates do not replace data measurements; they simply contextualize measurements and, as they are expressed as percentages (Availability, Accuracy) and absolute rates (Overall Health, Performance), they can be aggregated to provide concise status overviews of systems under test. Specific measurement values remain important for in-depth analysis, experienced analysts, service target agreements, and notifications.
