El agente de Cloud Monitoring recopila métricas del sistema y de la aplicación de tus instancias de VM y las envía a Monitoring. También puedes configurar el agente de Monitoring para supervisar las aplicaciones de terceros.
En esta guía, se explica cómo instalar el agente de Cloud Monitoring para Monitoring en las VM de Compute Engine. Usar el agente es opcional, pero se recomienda para las instancias de VM de Compute Engine. En estas VM, Monitoring puede acceder a algunas métricas del hipervisor de VM sin el agente, incluido el uso de CPU, algunas métricas de tráfico de disco, el tráfico de red y el tiempo de actividad.
En las instancias que ejecutan Microsoft Windows, el agente registra el uso de CPU y la memoria, el archivo de paginación y el uso del volumen. Si ejecutas el servidor IIS o SQL, el agente colecta métricas de esos servicios de manera predeterminada.
Instala una versión específica del agente
Para instalar una versión específica del agente, completa los siguientes pasos.
Descarga el agente en la maquina virtual, has de tener acceso mediante ssh.
[simterm][root@todolinux ~]# curl -sSO https://dl.google.com/cloudagents/add-monitoring-agent-repo.sh [root@todolinux ~]# ls -lrt total 24 -rw-------. 1 root root 1201 Oct 27 04:45 anaconda-ks.cfg -rw-r--r--. 1 root root 19195 Dec 28 10:25 add-monitoring-agent-repo.sh [root@todolinux ~]# [/simterm]
Ejecuta el script descargado y veras como se añade un repositorio de Cloud Monitoring.
[simterm][root@todolinux ~]# bash add-monitoring-agent-repo.sh

Si necesitas para otro tipo de SO que no sea linux, te dejo este link donde lo explican.
Nota: Si actualizaste el sistema operativo Linux de tu instancia a una nueva versión principal, es mejor que no actualices el agente con este procedimiento, sino que lo quites y, luego, vuelvas a instalarlo según los procedimientos que se indican en esta página.
