Sentinel Agent
The Sentinel agent is Lutflow's real-time GPU telemetry component. It continuously collects metadata telemetry from inside the workload's execution environment, turning passive cost observation into a live stream. Sentinel is monitoring-only and metadata-only — it measures and reports, it does not enforce; cost enrichment happens downstream on the platform. Zero application changes required. Compatible with Kubernetes and GKE.
Technical Explanation
The Sentinel agent is deployed as a Kubernetes sidecar container or DaemonSet alongside AI inference workloads. It collects compute metadata at the infrastructure level — GPU utilization, memory allocation, inference throughput — and emits it as telemetry. Cost enrichment against provider and marketplace rates happens downstream on the platform, not inside the agent. In the hosted product Sentinel is monitoring-only and metadata-only: when accrued cost approaches or exceeds a budget threshold, the breach is surfaced to operators. Sentinel takes no enforcement action, terminates nothing, and offers no kill-path latency figure. Automatic termination is the Financial Firewall, a sub-product in development, decoupled from this measurement pipeline and carrying no production SLA. Installation requires zero application code changes — the Sentinel runs below the application layer.
Business Explanation
The Sentinel supports one question at all times: 'What is this inference workload costing right now?' The agent supplies the live telemetry; the platform enriches it into cost. For CFOs, this reduces billing surprises — you see the cost before the invoice arrives. For FinOps teams, it provides the real-time telemetry feed that existing tools lack. For CTOs, it provides infrastructure-level cost monitoring without requiring developers to instrument their code.
Lookup → Flow → Value
The Sentinel performs continuous collection of workload metadata telemetry, which the platform enriches into cost intelligence downstream. It does not enforce budget policy itself; that capability belongs to the Financial Firewall, a sub-product in development.

Frequently Asked Questions
What is the Sentinel agent?+
A real-time telemetry component that reports metadata for every inference workload so the platform can cost it. Monitoring-only and metadata-only. Deployed as a Kubernetes sidecar with zero code changes.
Does it require application changes?+
No. The Sentinel runs below the application layer as a Kubernetes sidecar or DaemonSet. No code instrumentation or SDK integration required.
Does the Sentinel stop workloads that breach budget?+
No. Hosted Sentinel is monitoring-only and metadata-only — it surfaces the breach and takes no action. Automatic termination belongs to the Financial Firewall, a sub-product in development that is decoupled from the hosted measurement pipeline and carries no production SLA.
