+# Despliega metrics_agent en un nodo remoto como servicio systemd.
+#
+# Uso: ./deploy_agent.sh <node_name> <ssh_host> [arch]
+#   node_name : valor de la label "instance" en Grafana (ej. homer)
+#   ssh_host  : alias SSH del nodo (debe existir en ~/.ssh/config)
+#   arch      : amd64 (default) | arm64
+#
+# Requisitos:
+#   - Binario compilado en apps/metrics_agent/dist/metrics_agent_<arch>
+#     (compila con: cd apps/metrics_agent && CGO_ENABLED=0 GOOS=linux GOARCH=<arch> \
+#                    go build -ldflags="-s -w" -o dist/metrics_agent_<arch> .)
+#   - `pass fleet/ingest-pass` con el password de ingesta.
+#   - sudo -n (sin password) disponible en el nodo remoto.
