Supported OS
Versión de la integración 4.1.0
Habilita la integración de Ceph con Datadog para:
Rastrear el uso del disco en los grupos de almacenamiento Recibir checks de servicio en caso de problemas Monitorizar las métricas de rendimiento de E/S Configuración Instalación El check de Ceph está incluido en el paquete del Datadog Agent , por lo que no necesitas instalar nada más en tus servidores Ceph.
Configuración Edita el archivo ceph.d/conf.yaml, que se encuentra en la carpeta conf.d/ en la raíz del directorio de configuración del Agent .
Para ver todas las opciones de configuración disponibles, consulta el ceph.d/conf.yaml de ejemplo :
init_config :
instances :
- ceph_cmd : /path/to/your/ceph # default is /usr/bin/ceph
use_sudo : true # only if the ceph binary needs sudo on your nodes
Si has habilitado use_sudo, añade una línea como la siguiente a tu archivo sudoers:
dd-agent ALL=(ALL) NOPASSWD:/path/to/your/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:
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.
logs :
- type : file
path : /var/log/ceph/*.log
source : ceph
service : "<APPLICATION_NAME>"
Reinicia el Agent .
Validación Ejecuta el subcomando de estado del Agent y busca ceph en la sección Checks.
