Logiciel de surveillance (au sens tout va bien) de serveurs (qui sont d'acccord pour être surveillés).
Dispo pour Debian et pour Raspbian.
Présentation
- logiciel surtout dans la galaxie linux (même s'il y a des versions macwindown)
- nécessite l'installation du logiciel surveillant (munin-master), mais aussi d'instances coopératives (munin-node) sur les serveurs/noeuds surveillés
- le serveur surveillant peut lui aussi être un surveillé (recommandé)
- munin s'installe sur un serveur, ie a priori sur un serveur at home, dédié ou VPS. a priori munin n'est pas dispo pour du mutualisé.
- munin produit ses résultats en temps que pages web, écrites à http://IP_ou_Nom_du_serveur/munin , la visualisation de ces pages nécessite qu'un serveur (apache, nginx) ait été installé préalablement (et configuré comme il faut)
- munin peut aussi générer des alertes mail
Installation
C'est un package officiel Debian.
apt-get install munin
, pour le surveillant, semble ok
apt-get install munin-node
, pour le(s) surveillé(s), semble ok
