It uses a datasource template variable, so it binds to Grafana's default Prometheus. The ConfigMap must live in a namespace the sidecar watches — set `prometheus.grafanaDashboard.namespace` to Grafana's namespace (or run the sidecar with `searchNamespace: ALL`).
 
+### Example Grafana dashboards
+Ready-to-import dashboards live under [`examples/dashboards/`](./examples/dashboards/):

+- [`memgraph_openmetrics.json`](./examples/dashboards/memgraph_openmetrics.json) — Memgraph metrics scraped directly from the OpenMetrics endpoint (`scrapeMemgraphDirectly=true`).
+- [`memgraph_victorialogs.json`](./examples/dashboards/memgraph_victorialogs.json) — Memgraph logs shipped by `vectorRemote`, queried from VictoriaLogs.
