define-slo-sli-sla

Establish measurable reliability targets with Service Level Objectives, track them with indicators, and manage error budgets.

Key principle: SLO should be stricter than SLA to provide buffer before customer impact.

Expected: Team understands differences, agreement on which metrics become SLIs, alignment on SLO targets.

使用 Prometheus 和 Sloth 或 Pyrra 等工具建立服务级别目标 (SLO)、服务级别指标 (SLI) 和服务级别协议 (SLA)，并提供错误预算跟踪、消耗率警报和自动报告。在为面向客户的服务定义可靠性目标、通过错误预算平衡功能速度与系统可靠性、从任意正常运行时间目标迁移到数据驱动的指标或实施站点可靠性工程实践时使用。 来源：pjt222/development-guides。
