Kustomizeobservability/loki/ — single-binary StatefulSet (in-cell); split-monolithic mode in cloud cells

Dependencies

Upstream: vector (the canonical shipper).

Downstream: grafana (datasource).

Operations

  • Storage: in-cell uses local PVC; cloud cells back with S3 / GCS / ADLS object storage.
  • Retention: 14 days default; 30 days for audit-* streams (per the audit-evidence retention policy).
  • Tenancy: every log line carries a tenant_id label so Loki's multi-tenancy split is enforced at query time.
