Pb 2
# docker exec -ti omsa82-snmp omreport chassis fans
Error! No fan probes found on this system.

Solution : Version plus récente de Dell openmanage

Supervision

Pb
# /usr/lib64/nagios/plugins/check_openmanage -H 172.18.205.2
SNMP ERROR [cooling]: The requested entries are empty or do not exist

Le pb vient d'openmanage, peut-être la version n'est pas assez récente

La commande suivante doit fonctionner

Debmirror pour Cobbler

Laisser la conf par défaut. Juste commenter les lignes suivantes @dists= et @arches= :

/etc/debmirror.conf 

@dists="sid";
@arches="i386";

Devient /etc/debmirror.conf 

#@dists="sid";
#@arches="i386";

Puis si cobbler check affiche toujours un avertissement sur debmirror, redémarrer le service cobblerd
