Open Source Network Monitoring Software

Pandora FMS is an enterprise-ready monitoring solution that provides unparalleled flexibility for IT to address both immediate and unforeseen operational issues, including infrastructure and IT processes. It uniquely enables business and IT to adapt to changing needs through a flexible and rapid approach to IT and business deployment. Pandora FMS consolidates all the needs of modern monitoring (ITOM, APM, BAM) and provides status and performance metrics from different operating systems, cloud, virtual infrastructure (VMware, Hyper-V, XEN), Docker containers, applications, storage and hardware devices such as firewalls, proxies, databases, web servers or routers. It's highly scalable (up to 2000 nodes with one single server), 100% web and with multi-tenant capabilities. It has a very flexible ACL system and several different graphical reports and user-defined control screens.

Conky is a free, light-weight system monitor for X, that displays any kind of information on your desktop. Conky is free software and runs in X on Linux and BSD. Originally a fork of Torsmo, Conky's torsmo-based code is BSD licensed. New code in Conky has been licensed under GPL 3.0. Since its inception, Conky has changed significantly from its predecessor, while maintaining simplicity and configurability. Conky can display just about anything, either on your root desktop, in its own window. Not only does Conky have many built-in objects, it can also display just about any piece of information by using scripts and other external programs. A plethora of OS stats (uname, uptime, CPU usage, mem usage, disk usage, "top" like process stats, and network monitoring, just to name a few). Conky can display information either as text, or using simple progress bars and graph widgets, with different fonts and colours.

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. Supports clusters up to 2000 nodes in size.

The program thrulay is used to measure the capacity, delay, and other performance metrics of a network by sending a bulk TCP or UDP stream over it.

Jnettop allows administrators of routers to watch online traffic coming across the network in a fashion similar to the way top displays statistics about processes. It is useful for quickly evaluating the state of the network.

Bandwidth Monitor NG is a small and console-based live network and disk-io bandwidth monitor for Linux, BSD, Solaris, Mac OS X and others. features: output of KB/s, Kb/s, packets, errors, average, max and total sum; in curses, plain console, CSV or HTML MOVED TO: https://github.com/vgropp/bwm-ng

The Neighbor Discovery Protocol Monitor (NDPMon) is used by Internet Protocol version 6 network administrators for monitoring ICMPv6 packets. NDPMon observes the local network for anomalies in the function of nodes using Neighbor Discovery Protocol (NDP) messages, especially during the Stateless Address Autoconfiguration. When an NDP message is flagged, it notifies the administrator by writing to the syslog or by sending an email report. It may also execute a user-defined script. For IPv6, NDPMon is an equivalent of Arpwatch for IPv4, and has similar basic features with added attacks detection. NDPMon also maintains up-to-date a list of neighbors on the link and watches all advertisements and changes. It permits to track the usage of cryptographically generated interface identifiers or temporary global addresses when Privacy extensions are enable (default behavior in Ubuntu and Windows for example).

Nagisk is a simple tool to monitor Asterisk from a Nagios server.

A set of python scripts to provide command-line access to GroundWork Open Source. gwcmd allows to perform operations from commandline, and from remote servers.

Impost is a network security auditing tool designed to analyze the forensics behind protocol exploitation.

A platform Neutral Monitor Service Container/Framework

Monitorix is a free, open source, lightweight system monitoring tool designed to monitor as many services and system resources as possible. It has been created to be used under production Linux/UNIX servers, but due to its simplicity and small size may also be used on embedded devices as well.

The OpenLANscape project's goal is to develop and implement algorithms to draw network physical topology maps.

Oreon will be renamed in Centreon in july 2007. 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 functionnalit

Pace-ICMP is a utility that can allow X amount of ICMP (ping, etc) packets travel to the host, once X is exceeded, all ICMP traffic is blocked. This allows ping and traceroute functionality, while still protecting you against ICMP attacks.

PortscanGeoinfo is a plugin for the powerful Prelude correlation engine. This plugin correlates alerts from Snort NIDS and OSSEC HIDS sensors regarding portscans. Geographical information (GeoIP) is included in the correlated alert.

Squeezer is a multi-dimensional logfile analyzer for Squid web cache server. It measures transfer speed from Squid, source servers and other caches and gives an information useful for tuning Squid and web cache hierarchy or mesh.

WiR3D is a simple tool to scan LANs, discover nodes and topology using SNMP. It has a feature to visualize the topology of scanned subnets as a 3D scene. In the future more features will be implemented to turn WiR3D into NMS app with GTK GUI.

Packet Filter (PF) is OpenBSD\'s firewall and traffic shaper. This is a port of this excellent software to FreeBSD.
