Slo

• BudgetExhausted

  A rollout is frozen because the service is out of its SLO error budget.

• BudgetSourceUnavailable

  A metric source for an error-budget freeze or a promotion analysis could not be read.

• Dashboard

  The StageSet controller ships a maintained Grafana dashboard as a single-layer OCI image — render it through JaaS and hand it to the grafana-operator.

• Error-budget freeze

  Freeze new-revision rollouts while a service is out of its SLO error budget, resuming on its own when it recovers.

• Service level objectives

  The StageSet controller's SLOs — reconcile availability and reconcile latency — with their SLIs, targets, error budget, the dashboard that shows them, and how to tune them.
