[technique] problème smokeping

[Luc Maisonobe]

Bonjour,

Le smokeping qui surveille le réseau sans fil de Monès génère de
nombreuses erreurs. Je ne donne pas l'adresse, car il me semble
qu'elles sont confidentielles. Les messages sont du genre :

Je ne sais pas si c'est un disque saturé ou un autre truc du genre. Je
ne sais même pas quelle machine fait cette surveillance, et ne sais donc
pas comment chercher la cause de l'erreur.

Y aurait-il quelqu'un au courant des arcanes de ce réseau qui pourrait
regarder ?

cordialement,
