analyze-node-tuning

analyze-node-tuning is a command for Claude Code from openshift-eng/ai-helpers. It costs 18 tokens per session (2,024 once invoked), scanned A, original, Apache-2.0.

A command that checks kernel and system tuning on an OpenShift node using a live node, a captured snapshot, or a sosreport. It examines CPU isolation, interrupt handling, huge pages, system settings, and network counters, then proposes Node Tuning Operator recommendations.

In plain words
What is it for?
Use it to audit node performance settings and produce JSON or Markdown findings for incident response, CI checks, or documentation.
Why use it?
It helps find tuning regressions after upgrades or configuration changes and turns observations into possible remediation steps.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

analyze-node-tuning scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Synopsis

/node-tuning:analyze-node-tuning [--sosreport PATH] [--collect-sosreport|--no-collect-sosreport] [--sosreport-output PATH] [--node NODE] [--kubeconfig PATH] [--oc-binary PATH] [--format json|markdown] [--max-irq-samples N] [--keep-snapshot]

Description

The node-tuning:analyze-node-tuning command inspects kernel tuning signals gathered from either a live OpenShift node (/proc, /sys), an oc debug node/<name> snapshot captured via KUBECONFIG, or an extracted sosreport directory. It parses CPU isolation parameters, IRQ affinity, huge page allocation, critical sysctl settings, and networking counters before compiling actionable recommendations that can be enforced through Tuned profiles or MachineConfig updates.

Use this command when you need to:

  • Audit a node for tuning regressions after upgrades or configuration changes.
  • Translate findings into remediation steps for the Node Tuning Operator.
  • Produce JSON or Markdown reports suitable for incident response, CI gates, or documentation.

Implementation

  1. Establish data source
    • Live (local) analysis: the helper script defaults to /proc and /sys. Ensure the command runs on the target node (or within an SSH session / debug pod).
    • Remote analysis via oc debug: provide --node <name> (plus optional --kubeconfig and --oc-binary). The helper defaults to entering the RHCOS toolbox (backed by the registry.redhat.io/rhel9/support-tools image) via oc debug node/<name>, running sosreport --batch --quiet -e openshift -e openshift_ovn -e openvswitch -e podman -e crio -k crio.all=on -k crio.logs=on -k podman.all=on -k podman.logs=on -k networking.ethtool-namespaces=off --all-logs --plugin-timeout=600, streaming the archive locally (respecting --sosreport-output when set), and analyzing the extracted data. Use --toolbox-image (or TOOLBOX_IMAGE) to point at a mirrored support-tools image, --sosreport-arg to append extra flags (repeat per flag), or --skip-default-sosreport-flags to take full control. Host HTTP(S) proxy variables are forwarded when present but entirely optional. Add --no-collect-sosreport to skip sosreport generation entirely, and --keep-snapshot if you want to retain the downloaded files.
    • Offline analysis: provide --sosreport /path/to/sosreport-<timestamp> pointing to an extracted sosreport directory; the script auto-discovers embedded proc/ and sys/ trees.
    • Override non-standard layouts with --proc-root or --sys-root when auto-detection fails to locate the correct proc/ or sys/ trees.

analyze-node-tuning is a command published in the GitHub repository openshift-eng/ai-helpers (116 stars, last pushed today), licensed Apache-2.0. It adds 18 tokens to every session and 2,024 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
