Nagios is a powerful, modular network monitoring system that can be used to monitor many network services like smtp, http and dns on remote hosts. It also has support for snmp to allow you to check things like processor loads on routers and servers. I couldn't begin to cover all of the things that nagios can do in this article, so I'll just cover the basics to get you up and running.

Cela fait près d’un an et demi que j’utilise le logiciel Cacti pour monitorer l’activité réseau. Aussi bien dans le cadre de mon activité professionnelle que pour mon usage personnel. Mais j’ai récement découvert une alternative sérieuse : Munin. Celui-ci présente de nombreux avantages par rapport à Cacti et mérite d’être plus connue.

Munin the monitoring tool surveys all your computers and remembers what it saw. It presents all the information in graphs through a web interface. Its emphasis is on plug and play capabilities. After completing a installation a high number of monitoring plugins will be playing with no more effort. Using Munin you can easily monitor the performance of your computers, networks, SANs, applications, weather measurements and whatever comes to mind. It makes it easy to determine "what's different today" when a performance problem crops up. It makes it easy to see how you're doing capacity-wise on any resources.

ctail is like running tail -f, but can be used on multiple files. It uses the Curses library to split the screen into as many windows as there are files to watch. The size of each file's window can optionally be specified on the command line. Regular expressions can be used to display only lines matching (or not matching) arbitrary criteria. Each file's window has a status bar, showing the file name, date and time of last change and current file size.

IPTables log analizer (TODO : find a nice name for it) displays Linux 2.4 iptables logs (rejected, acepted, masqueraded packets...) in a nice HTML page (it support rough netfilter logs but also Shorewall and Suse Firewall logs). This page shall be easy to read and understand to reduce the manual analysis time. This page containts statistics on packets and links to more detailled information on a given host, port, domain and so on.

Firewall Eyes est un outil d'analyse de logs en temps réel pour le pare-feu iptables. Grâce à une interface Web, vous visualisez et supervisez simplement et efficacement l'activité réseau traversant votre firewall. Vous détectez aisément les activités suspectes et ajustez votre politique de sécurité.

La gestion d'un parc de serveur est un travail de chaque instant. Un bon administrateur système doit savoir à tout moment l'état des différentes machines et des différents services. Un autre aspect clé est que l'administrateur ne peut pas se permettre de passer son temps devant un tableau avec des voyants verts en attendant qu'un voyant passe au rouge pour agir. Son temps est occupé à d'autres tâches et il ne peut donc pas surveiller le tableau de statut en permanence.
