#+END_SRC
*** Vérification de santé générale
La commande =vps check-fix= contrôler les containers en cours de
fonctionnement pour vérifier s'ils ne sont pas touché par quelques
problème identifiés et connus. Et elle va réparer ce qu'elle peut.
#+begin_src sh
vps check-fix
#+end_src
Il est possible de lancer ces vérifications sur une liste de service
spécifique ou de sélectionner le test voulu. Voir =vps check-fix
--help= pour plus d'info.
Il peut être opportun d'ajouter dans sur l'hôte, par exemple, une
vérification périodique et automatique:
#+begin_src sh
cat <<EOF > /etc/cron.d/vps-check
SHELL=/bin/bash
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin
*/15 * * * * root vps check-fix -s -c container-aliveness 2>&1 | logger -t check-fix
*/5 * * * * root vps check-fix -s rocketchat 2>&1 | logger -t check-fix
EOF
#+end_src
** Par services
