by lecyborg
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.

Monitoring Servers and Clients using Munin in Ubuntu

by lecyborg
“Munin” means “memory”.Munin the tool surveys all your computers and remembers what it saw. It presents all the information in 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, and quite possibly applications as well. 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 all limited resources. It uses the excellent RRDTool and is written in Perl. Munin has a master/node architecture in which the master connects to all the nodes at regular intervals and asks them for sdata. It then stores the data in RRD files, and (if needed) updates the graphs. One of the main goals has been ease of creating new plugins (graphs).

zabbix

by lecyborg
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.
