Tout comme Nagios, Zenoss est un outil de supervision open-source gratuit (il existe une version commerciale comportant plus d’options). Il se base sur une application Web qui va surveiler les noeuds de votre réseau et générer des rapports si chers aux yeux des décideurs informatiques…

Opsview is enterprise network and application monitoring software designed for scalability, flexibility and ease of use. Opsview has been in development since 2003 and is released under the GNU GPL license. Current version is 2.12. Opsview is a fully integrated monitoring tool that incorporates popular Open Source software including Nagios, Net-SNMP and RRDtool. The Catalyst web framework provides an extensible monitoring and configuration user interface. Opsview software is supported on Linux (Debian, CentOS, RHEL and Ubuntu) and Solaris 10. It will monitor all common operating systems including Windows. Opsview extends the capabilities of Nagios in the following ways: * Distributed monitoring with high availability and fail-over * Much improved SNMP support with trap processing with rules engine * API supporting automation of Opsview configuration * Data warehouse for storage of historical performance and event data * Opsview Reports customisable reporting * Powerful configuration and management UI * Extended monitoring UI * Extensible architecture based on Catalyst Web Framework and Altinity middleware software

NagVis is a visualization addon for the well known network managment system Nagios. NagVis can be used to visualize Nagios Data, e.g. to display IT processes like a mail system or a network infrastructure. Key features are: * Display of single Hosts and Services * Visualize a complete Host- oder Servicegroup with one icon * Display the state of a Host dependent on the state of its services (“recognize services”) * Display only the real problems (“only_hard_states”) * Define Sub-Map icons wich represent a complete NagVis Map of Hosts/Services/Groups in one icon (drill down) * Visualization/Documentation of complete IT Processes and Infrastructures using self drawn graphics

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.

Centreon is a network, system, applicative supervision and monitoring tool, it is based upon the most effective Open Source monitoring engine : Nagios. Centreon provides a new frontend and new functionnalities to Nagios.Image It ables you to be more efficient in your network monitoring, but also allows you to make your supervision informations readable by a largest range of users. Indeed, a non technical user can now use the Centreon/Nagios couple to easily understand your network infrastructure thanks to charts and graphical representations of the gathered informations. Although, skilled users still have access to the technicals informations collected by Nagios. Centreon was released for three years, and has already conviced most of its everyday users. Oreon has became a reference as a Nagios Frontend. The Centreon/Nagios couple is used by a wide range of users, from novices to skilled users, even if they didn't knew Nagios before.

NagiosVMA is virtual machine appliance that runs Nagios, a powerful, open-source application which performs host, service and network monitoring. Additionally, the appliance was enhanced with Groundwork Monitor Architect, an open-source, web-based, configuration tool for Nagios. It is intended to offer the end-user sophisticated network monitoring in minutes, instead of hours, (or even days) as is typical with building and configuring a Linux/Nagios host. Using Nagios combined with Monarch and Monarch's automatic host discovery feature, this virtual machine appliance can be booted, configured, and ready to monitor your network in as little as 10 minutes. (in fact, as soon as it boots, its already monitoring this virtual machine appliance!)

This virtual appliance contains a ready to use ossim deployment. For detailed information about OSSIM please refer to http://www.ossim.net Ossim stands for Open Source Security Information Management. Its goal is to provide a comprehensive compilation of tools which, when working together, grant a network/security administrator with detailed view over each and every aspect of his networks/hosts/physical access devices/server/etc... Besides getting the best out of well known open source tools, some of which are quickly described below these lines, ossim provides a strong correlation engine, detailed low, mid and high level visualization interfaces as well as reporting and incident managing tools, working on a set of defined assets such as hosts, networks, groups and services.
