+## Grafana dashboard
+
+The Grafana dashboard lives in `dashboards/sonic-exporter.json`. It is a single-switch drilldown dashboard for Grafana 10 and Grafana 11.
+
+Rows are ordered this way:
+
+- `Overview / Exporter Health`
+- `Interfaces / Queues`
+- `Hardware / CRM / Host`
+- `Topology / L2`
+- `Optional / FDB`
+- `Optional / System`
+- `Optional / Docker`
+- `Optional / FRR`
+
+The optional rows are collapsed by default and are safe when those metrics are absent. Validate dashboard changes with:
+
+```bash
+./scripts/validate-dashboard.sh dashboards/sonic-exporter.json
+```
+
+For import, provisioning, variables, validation, smoke checks, and limits, see `docs/grafana-dashboard.md`.

+# SONiC Exporter Grafana Dashboard
+
+This dashboard gives operators a single-switch view of SONiC exporter health, traffic, and service state.
+It is built for Grafana 10 and Grafana 11 and is meant to be portable across Prometheus setups.
+
+## What the dashboard does
+
+The dashboard helps you check whether `sonic-exporter` is collecting data, which collectors are active, and whether the main SONiC subsystems are healthy.
+It is focused on drilldown for one switch at a time, not fleet overview.
+
+## Requirements
+
+- Grafana 10 or Grafana 11.
+- A Prometheus data source that scrapes `sonic-exporter`.
+- Metrics from the default collectors, plus any optional collectors you enable.
+
+## Import in Grafana
+
+Import `dashboards/sonic-exporter.json` from the Grafana dashboard import screen.
+Pick the Prometheus data source when Grafana asks for the dashboard data source.
+
+If you prefer the API, import the same JSON file through the Grafana dashboard import endpoint.
+
+## Provisioning option
+
+You can also provision the dashboard from `dashboards/sonic-exporter.json`.
+Keep the file path stable and point Grafana at the checked-in JSON so the dashboard stays in sync with the repo.
+
+## Variables
+
+The dashboard uses these variables only:
+
+- `datasource`, the Prometheus data source for `sonic-exporter`.
+- `job`, the Prometheus job label for the exporter scrape target.
+- `instance`, the Prometheus instance label for one switch.
+
+Do not add site, role, or hostname variables unless the dashboard design changes later.
+
+## Row order
+
+The checked-in dashboard uses this final row order:
+
+- `Overview / Exporter Health`
+- `Interfaces / Queues`
+- `Hardware / CRM / Host`
+- `Topology / L2`
+- `Optional / FDB`
+- `Optional / System`
+- `Optional / Docker`
+- `Optional / FRR`
+
+The first four rows are expanded by default. They cover exporter health, interface and queue traffic, hardware, CRM, host health, LLDP, VLAN, and LAG signals.
+
+The optional FDB, System, Docker, and FRR rows are collapsed by default. They do not need to return data for the default dashboard to be useful.
+
+## Validation command
+
+Run these commands after changing the dashboard JSON:
+
+```bash
+jq empty dashboards/sonic-exporter.json
+./scripts/validate-dashboard.sh dashboards/sonic-exporter.json
+go test ./...
+```
+
+## Grafana 10 and 11 smoke test
+
+The smoke test imports the dashboard into Grafana 10 and Grafana 11 with Docker, then confirms the `datasource`, `job`, and `instance` variables are present.
+
+Example Grafana images for a local smoke test:
+
+```bash
+docker run -d --name sonic-exporter-grafana-10-smoke-task10 -p 127.0.0.1:13010:3000 grafana/grafana:10.4.15
+docker run -d --name sonic-exporter-grafana-11-smoke-task10 -p 127.0.0.1:13011:3000 grafana/grafana:11.6.0
+```
+
+If Docker or Grafana cannot run in your environment, record the exact error message in your validation notes. Do not hide the failure.
+
+## Known limits and cardinality warnings
+
+- This dashboard is for one switch at a time, not a fleet summary.
+- Keep labels bounded. Do not add high-cardinality labels to panels.
+- Optional collectors may be absent on some switches, so panels for them should not be required for the dashboard to load.
+- The dashboard should stay portable, so avoid hard-coded hostnames, site names, or private IPs in the JSON or docs.
