summary
Argues that keeping Prometheus instances local while centralizing access via Grafana cuts egress and storage costs: they use per-cluster Prometheus, a central Grafana that queries each Prometheus (avoiding Federation), and Linkerd multi-cluster mirroring so Grafana sees remote targets as local. Key numbers and practices: two-day retention to skip long-term storage, use of Linkerd service mirror and multi-cluster Gateway, deploying via Helm/ArgoCD and performing trust anchor rotation by bundling old and new CAs with no downtime.
