+# Grafana Dashboards for Go Services
+
+These community Grafana dashboards visualize Go runtime performance out of the box. They display the metrics automatically exposed by `github.com/prometheus/client_golang` — no custom instrumentation needed.
+
+## Recommended Dashboards
+
+| Dashboard | ID | What it shows |
+| --- | --: | --- |
+| [Go Host & Runtime Metrics](https://grafana.com/grafana/dashboards/21221-go-host-runtime-metrics-dashboard/) | 21221 | Host metrics + Go runtime (goroutines, heap, GC, threads) in one view |
+| [Go Processes](https://grafana.com/grafana/dashboards/6671-go-processes/) | 6671 | Multi-process comparison — CPU, memory, goroutines, GC across all Go services |
+| [Go Metrics](https://grafana.com/grafana/dashboards/10826-go-metrics/) | 10826 | Focused Go runtime view — memory breakdown, GC pauses, allocations, goroutines |
+
+## How to Install
+
+Dashboards are imported via **Dashboards > New > Import** in Grafana using the dashboard ID (e.g., `21221`), then selecting the Prometheus data source.
+
+These dashboards require the default Go collector metrics (`go_goroutines`, `go_memstats_*`, `go_gc_duration_seconds`, `process_*`). If you use the Prometheus client library with default collectors, everything works out of the box.
+
+## When to Use Each
+
+- **21221** (Host & Runtime) — day-to-day monitoring of a single Go service alongside its host. Best as the default Go dashboard.
+- **6671** (Go Processes) — comparing multiple Go services or replicas side by side. Useful during deployments to spot regressions across instances.
+- **10826** (Go Metrics) — deep-diving into memory and GC behavior of a single service. Best for investigating performance issues.
