What Are Metrics, Logs, and Traces?
Metrics, logs, and traces are the three pillars of observability: metrics are aggregated numeric time-series data showing system health at a glance, logs are t…
How Do You Design Effective Alerting?
Effective alerting fires only on symptoms that indicate real, actionable user-facing impact — not on every internal anomaly — and every alert should be tied to…
What Are SLIs, SLOs, and SLAs?
An SLI (Service Level Indicator) is a measured metric of user-facing performance like request success rate, an SLO (Service Level Objective) is the internal ta…
What is an Error Budget?
An error budget is the allowed amount of unreliability a service can accumulate before breaching its SLO, calculated as 100% minus the SLO target over the meas…
