# Service SLOs Service level objectives define availability, latency, and queue health expectations for core services. Typical SLOs (example) - API availability target per month. - P95 run duration target for standard workflows. - Queue backlog thresholds per tenant. - Event delivery success targets. Operational practice - Track error budgets over a rolling window. - Alert on burn rates and sustained backlog. - Keep dashboards aligned with SLO definitions.
