init_config:instances:- ceph_cmd:/path/to/your/ceph# la opción predeterminada es /usr/bin/cephuse_sudo:true# solo si el binario ceph necesita sudo en los nodos
Si has habilitado use_sudo, añade una línea como la siguiente a tu archivo sudoers:
dd-agent ALL=(ALL) NOPASSWD:/ruta/a/tu/ceph
Recopilación de logs
Disponible para la versión 6.0 o posteriores del Agent
La recopilación de logs está deshabilitada por defecto en el Datadog Agent; habilítala en tu archivo datadog.yaml:
logs_enabled:true
Luego, edita ceph.d/conf.yaml al quitar los comentarios de las líneas logs de la parte inferior. Actualiza la path de los logs con la ruta correcta a tus archivos de logs de Ceph.
