Xymon is a tool for monitoring servers, applications and networks. It collects information about the health of your computers, the applications running on them, and the network connectivity between them. All of this information is presented in a set of simple, intuitive webpages that are updated frequently to reflect changes in the status of your systems.

OSSEC is an Open Source Host-based Intrusion Detection System. It performs log analysis, file integrity checking, policy monitoring, rootkit detection, real-time alerting and active response.

Hosted log management for servers, apps, and cloud services.

You have a router, you want to know what it does all day long? Then MRTG is for you. It will monitor SNMP network devices and draw pretty pictures showing how much traffic has passed through each interface.

The Percona Monitoring Plugins are high-quality components to add enterprise-grade MySQL monitoring and graphing capabilities to your existing in-house, on-premises monitoring solutions. The components are designed to integrate seamlessly with widely deployed solutions such as Nagios and Cacti, and are delivered in the form of templates, plugins, and scripts.

"Open Source Tripwire® software is a security and data integrity tool useful for monitoring and alerting on specific file change(s) on a range of systems. The project is based on code originally contributed by Tripwire, Inc. in 2000."

Monit is a free open source utility for managing and monitoring, processes, programs, files, directories and filesystems on a UNIX system. Monit conducts automatic maintenance and repair and can execute meaningful causal actions in error situations.

Munin is a networked resource monitoring tool that can help analyze resource trends and "what just happened to kill our performance?" problems. It is designed to be very plug and play. A default installation provides a lot of graphs with almost no work.

Canopsis est un jeune projet démarré début 2011. Initié par la SSLL Capensis, il bénéficie de tout son soutien financier et humain. En outre, de nombreux partenaires épaulent Canopsis dont l’OSEO et l’Union Européenne. Pas de mauvaise surprise à attendre, Canopsis est livré en version AGPL3. Vous pouvez découvrir l’architecture de Canopsis.

Mod_Gearman is an easy way of distributing active Nagios/Icinga checks across your network and increasing Nagios scalability. Mod-Gearman can even help to reduce the load on a single Nagios host, because its much smaller and more efficient in executing checks.

A one-file-script for debug and monitor your web

Nagios or Icinga Web interface based on NDO. It allows you to view almost everything about Nagios or Icinga in a single page: alert, ack, downtime, comment. You can also interact with Nagios or Icinga through ack, downtime, comment, disable, and reset buttons. You can filter on hosts and services states (critical, warning, unknown, ok, outage...). The status popin allows to display graphs, either the ones from Nagios (trends.cgi) or custom ones based on RRD (pnp4nagios, ...).

Thruk is an independent multibackend monitoring webinterface which currently supports Nagios, Icinga and Shinken as backend using the MKLivestatus addon. It is designed to be a "dropin" replacement. The target is to cover 100% of the original features plus additional enhancements for large installations.

Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and Grids. It is based on a hierarchical design targeted at federations of clusters. It leverages widely used technologies such as XML for data representation, XDR for compact, portable data transport, and RRDtool for data storage and visualization. It uses carefully engineered data structures and algorithms to achieve very low per-node overheads and high concurrency. The implementation is robust, has been ported to an extensive set of operating systems and processor architectures, and is currently in use on thousands of clusters around the world. It has been used to link clusters across university campuses and around the world and can scale to handle clusters with 2000 nodes.

Welcome to OMD - the Open Monitoring Distribution. OMD implements a completely new concept of how to install, maintain and update a monitoring system built on Nagios.

VNStat est un outil bien utile pour surveiller le débit des interfaces réseaux de ses machines. Il se présente sous la forme d'un processus tournant en tache de fond (les versions plus anciennes se basaient sur crontab) et surveillant les flux transitant sur vos interfaces. Nous allons détailler l'installation et l'utilisation de cet outil sur

Surveiller ses fichiers de log est une activité nécessaire[1] mais bien souvent rébarbative.

Open source monitoring for networks, servers and more. Set up custom checks, get alerts fast and keep full control of your infrastructure.
