SLI

Service Level Indicator

A specific metric used to measure the achievement of an SLO, such as endpoint availability, error rate, response latency, or task completion time.

Why it matters

Turns a reliability goal into a measurable metric: exactly what we measure (error rate, response time), where and how. Without an indicator, the goal is just a declaration.

What's missing without it

Without defined indicators, disputes over whether a service 'works well' are resolved by opinions rather than data.

When it is used

When defining SLO goals and building monitoring — each goal gets its own measurable indicator.

How we use it

SLI measures the percentage of successful responses from the article publishing endpoint over 30 days.
