Docs review: Karpenter monitoring

Reviewed with the signoz-docs-pr-review skill against contributing/docs-review.md + docs-authoring.md. Two docs, plus sidebar/listicle/icon discovery updates. Overall this is careful, well-scoped work: happy path is clean, technical claims check out against the Karpenter metrics reference, endpoints use the <region> token, images are high-res WebP via Figure, no em dashes, code-fence collapse flags are correct.

Findings

P1

• Dashboard JSON URL 404s — karpenter-dashboard.mdx:23. dashboardJsonV2Url targets SigNoz/dashboards/.../karpenter/karpenter-dashboard.json, but that folder does not exist in the SigNoz/dashboards repo (gh api repos/SigNoz/dashboards/contents/karpenter → 404). Copy/Download will fail until the dashboard JSON is merged there. Publish the JSON first, then confirm the raw URL resolves.

P3

• Description over length — karpenter-dashboard.mdx:4. ~164 chars vs. the 120–160 guideline; trim one clause.
• Vague cross-link — karpenter-dashboard.mdx:108. "cardinality guidance in the setup guide" links to the setup page root; an anchor to the relevant section would land readers on the exact content.

Technical accuracy (verified)

• Default metrics port 8080 at /metrics, METRICS_PORT override, http-metrics container port name, and the listed karpenter_* metrics all match the Karpenter metrics reference. ✅
• The otlphttp → otlp_http deprecation note is correct — otlphttp is now a deprecated alias in recent Collector releases. ✅
• Prometheus role: pod + keep on http-metrics port name is valid SD behavior; leader-election caveat is accurate. ✅

Personas & fit

Platform/SRE engineers running Karpenter on Kubernetes who want autoscaling telemetry in SigNoz. The setup doc (howto) serves the "get metrics flowing" job well; the dashboard doc (explanation) serves "interpret the fleet" well. Fit is strong; the two docs cross-link cleanly.

JTBD coverage

Title/description lengths in range (dashboard description slightly long, P3). Single clear default path, minimal mandatory steps, concrete ## Validate with exact SigNoz UI steps and a success signal, symptom-first ## Troubleshooting, useful ## Next Steps. Cardinality/advanced material correctly pushed into collapsed sections. No mandatory-path bloat.

Checklist coverage

Frontmatter complete (date, title, description, doc_type); tags omitted correctly (applies to Cloud + Self-Host). Sidebar, both listicles, and the new brand icon are all added and alphabetized. No URL changes → no redirects needed. Images are WebP and well above 1200px.

Open questions / assumptions

• Blocking item is external to this repo: the dashboard JSON must land in SigNoz/dashboards. Assuming that's in flight — flagging so it isn't missed.

Onboarding label

Onboarding label: applied — matched data/docs/metrics-management/opentelemetry-karpenter-metrics.mdx (new added file whose primary job is sending metrics to SigNoz, with endpoint + signoz-ingestion-key + OTLP exporter setup). The dashboard-template page on its own does not qualify.
