TL;DR: Kubernetes observability becomes expensive when telemetry policy is delegated to dozens of service teams, because cluster-level collection, churn-driven cardinality, and retention drift turn normal platform behaviour into runaway cost, according to Sawmills. The practical fix is central policy enforcement at the collector layer, where runtime controls can bound volume, attribution, and routing.
Editorial analysis by NHI Mgmt Group, based on content published by Sawmills: “Kubernetes observability for platform teams, from kubelet metrics to cost-controlled telemetry”.
Key questions
Q: What breaks when Kubernetes observability policy is left to individual service teams?
A: The cluster starts to accumulate cost, cardinality, and retention decisions that no single team can see end to end.
Q: Why do Kubernetes telemetry costs rise faster than service growth?
A: Because pod churn, redeployments, and restart-heavy workloads create new label combinations and more log volume even when business behaviour is unchanged.
Q: How do platform teams know if observability attribution is failing?
A: When dashboards stop tying telemetry back to namespace, deployment, or owner annotations, the collector may still be healthy while governance has already slipped.
Practitioner guidance
- Define approved telemetry policy at the collector layer Specify which logs, metrics, traces, labels, and namespaces are allowed to pass, then enforce those rules in the gateway or equivalent central collector so service teams cannot bypass them.
- Remove transient identifiers from bill-driving metric labels Review Kubernetes metrics for pod UID, container ID, and other churn-heavy fields that create unnecessary series growth, then replace them with stable service and namespace dimensions.
- Validate metadata enrichment and attribution RBAC Test that the k8sattributes path can read pods, namespaces, deployments, and replicasets, and confirm that ownership annotations still appear in downstream dashboards after every collector change.
Bottom line: Kubernetes observability becomes a platform governance issue when telemetry volume, ownership, and billing are separated across many teams.

Kubernetes observability cost is a policy failure, not a tooling failure. The article makes clear that each team can make locally sensible instrumentation choices while the platform absorbs the aggregate cost. That creates a governance mismatch between source ownership and financial ownership, which is exactly why telemetry policy has to be centralised at the substrate. The practitioner takeaway is that observability spend should be managed as a platform control problem, not a service-team etiquette problem.
A few things that frame the scale:
- 52% of respondents see AI security decision-making power shifting toward platform and infrastructure teams rather than the executive suite, according to the 2026 Infrastructure Identity Survey.
- Kubernetes production adoption has surged from 66% in CNCF's 2023 survey to 82% in 2025.
A question worth separating out:
Q: Should platform teams centralise telemetry routing and retention decisions?
A: Yes. Central routing and retention let the organisation apply consistent rules to logs, metrics, and traces across every cluster tenant. That is the only practical way to balance operational visibility with cost control, especially when multiple service teams share the same backend and billing model.
