Nagios - The Industry Standard in IT Infrastructure Monitoring Nagios This document will breeze through installing and configuring everything necessary to get Nagios up and running. This will not touch in detail on the actual configuration directives Nagios uses. For that, documentation is readily available from the Nagios website, or available locally after Nagios is installed. I'll be explaining installation through RPMs and yum from Dag's repo (RPMforge), but source is available if you prefer to build your own. Again, documentation for this is readily available. System: CentOS 4.x/5x (Should work for any RHEL/Fedora flavor.)

Open Monitoring Distribution - start Shinken Ce dossier a été réalisé par : Le projet Shinken consiste en une refonte complète du cœur de Nagios en Python, lui apportant une nouvelle architecture plus souple et plus facile à maintenir que le daemon monolithique actuel. Se basant sur une vue Unix, l’architecture se compose de daemons simples qui coopèrent afin de proposer les mêmes fonctionnalités que Nagios, voir plus. Le nom est inspiré des sabres Shinken japonais qui sont les armes les plus coupantes des guerriers.

How to manage Windows services with PowerShell | Sysadmin's tricks Here I’ll show you how to manage Windows services using PowerShell. First we need get services we will be working with: Commands: Get-Service gives you list of all services on the host but if you need more settings, it’s better to use WMI Get-WmiObject Win32_Service command. Using filter Where-Object we’re able to sort services as we want: Next we can manage services using Set-Service command: <#Set service named Servicename to Disable startup mode and Stop it, if no any dependencies: #> Set-Service -name Servicename -StartupType Disabled -Status Stopped # If service has dependencies, use following command to stop service: Stop-Service -Name Servicename -Force #Set service named Spooler to Auto startup mode and start it: Set-Service -name spooler -StartupType Automatic -Status Running Using all info above we are able manage services on Windows computers. Example 1: Set list of services to Disabled startup mode and Stop them: Example2: Set list of services to Auto startup mode and Start them:

Zabbix Dans ce dossier, figure une présentation des fonctionnalités de Zabbix, ainsi qu’un ensemble de documentations et de tutoriels sur la mise en place d’une architecture de supervision Zabbix. Pour toutes questions, informations complémentaires sur Zabbix, rendez-vous sur le forum du site. Zabbix ( est une solution de supervision open source. Ce logiciel permet de superviser des réseaux, et de surveiller les statuts de différents services, systèmes et réseaux. Un peu similaire à Nagios, Zabbix utilise un système de templates pour définir des hôtes à superviser, ce qui le rend très pratique pour la définition de grosses infrastructures. La partie serveur s’installe exclusivement sur Linux, quant à la partie agent, elle est disponible sur de nombreux systèmes d’exploitation (Windows, Linux, Solaris, FreeBSD, …etc, pour une liste plus complète voir ‘lien’), offrant ainsi une solution adaptive.
