AI Agent Audit Trail: What to Log for Every Tool Call
What an AI agent audit trail must record for each tool call: identity, policy version, verdict, approval, arguments digest, outcome, cost, trace IDs.
Comparisons and checklists for GPU admission, MCP security, LLM observability, and serving stacks — written from production platform work.

Practical guides on GPU schedulers, MCP and agent security, LLM vs MCP gateways, inference budgets, Argo CD vs Flux, vLLM autoscaling with KEDA, and KServe versus vLLM.
What an AI agent audit trail must record for each tool call: identity, policy version, verdict, approval, arguments digest, outcome, cost, trace IDs.
Argo CD vs Flux on Kubernetes: reconciliation models, Application vs HelmRelease, self-heal and prune, plus kind lab timings from a public duel repo.
Per-team inference budgets on the gateway path: reserve estimated cost before chat completion, settle after, fail closed. Status from ai-runtime-platform.
KServe and vLLM solve different layers of LLM serving on Kubernetes. What each does, how KServe runs vLLM, and when a plain vLLM Deployment is enough.
How Kueue, Volcano and NVIDIA KAI Scheduler differ for GPU inference and training on Kubernetes: architecture, queues, quotas and when to pick which.
LLM gateways govern model traffic; MCP gates control tool calls. Different boundaries and policies, with files from ai-runtime-platform and ASC.
A practical MCP security checklist for agents on Kubernetes: identity, token audience, tool pinning, egress, sandboxing, approvals and audit evidence.
Practical OpenTelemetry for LLMs: GenAI semantic conventions, token usage metrics, vLLM Prometheus metrics and a token cost pipeline on Kubernetes.
Each risk in the OWASP Top 10 for Agentic Applications mapped to Kubernetes controls you can enforce: identity, admission, egress, sandboxing, audit.
Scale vLLM on Kubernetes with KEDA on Prometheus queue metrics: ScaledObject shape, vllm:num_requests_waiting, and how this relates to KServe autoscaling.
