|
#
|
|
# Uso: ./deploy_agent.sh <node_name> <ssh_host> <role> [arch]
|
|
# node_name : valor de la label "instance" en Grafana (ej. homer)
|
|
# ssh_host : alias SSH del nodo (debe existir en ~/.ssh/config)
|
|
# role : label "role" para filtrar en Grafana (local | vps | movil)
|

|
|
# 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> .)
