NSClient++ is a windows service that allows performance metrics to be gathered by Nagios (and possibly other monitoring tools). It is an attempt to create a NSClient and NRPE compatible but yet extendable performance service for windows.

Osquery is an operating system instrumentation framework for Windows, OS X (macOS), Linux, and FreeBSD. The tools make low-level operating system analytics and monitoring both performant and intuitive. Osquery exposes an operating system as a high-performance relational database. This allows you to write SQL queries to explore operating system data. With osquery, SQL tables represent abstract concepts such as running processes, loaded kernel modules, open network connections, browser plugins, hardware events or file hashes.Osquery queries your devices like a database. Osquery uses basic SQL commands to leverage a relational data-model to describe a device. Frequently, attackers will leave a malicious process running but delete the original binary on disk. This query returns any process whose original binary has been deleted, which could be an indicator of a suspicious process.

nload is a console application which monitors network traffic and bandwidth usage in real time. It visualizes the in- and outgoing traffic using two graphs and provides additional info like total amount of transfered data and min/max network usage.

Why to pay tens of thousands $$$ for your network management software? Get visibility into your networks and complex processes inside with NG-NetMS now! NG-NetMS is a new end-to-end network management platform for your Linux servers, Cisco, Juniper, HP and Extreme routers, switches and firewalls. NG-NetMS is precise, quick and efficient. It collects most complete information about the network inventory, topology, map of IPv4 addresses quickly and with minimum hassle. Most important you will be able to collect, process and analyse Syslog events and SNMP alarms both in near-real-time and from the historical archives in a new way. We successfully used NG-NetMS for delivery of network assessment services for our customers worldwide for many years. And now we want to share this unique and fully functional tool with community. It is not capped in terms of performance or number of nodes. The only limit is the hardware you deploy it on. http://www.opt-net.eu/

A tool to monitor and analyse data transmitted between clients and a server through a TCP connection. This tool focuses on the data stream (software layer), not on the lower level transmission protocol as packet sniffers do.

NLog is a logging platform for .NET with rich log routing and management capabilities. It uses familar logger pattern known from log4xxx. Advanced routing options include buffering, asynchronous logging, load balancing, failover, and more.

ATTENTION: Snare Lite is unsupported legacy software. While it will remain a part of the SourceForge community, it is no longer secure and compliant. For up to date Snare software check out Snare Enterprise. https://www.snaresolutions.com/try-snare-for-free/ Snare Enterprise was created to keep up with the fast paced security software market. It started with the desire to create premium logging and SIEM tools that were agnostic by nature so they could be used to boost any SIEM architecture regardless of third party developers. In fact, the agnostic nature allows it to bridge gaps between multiple SIEM implementations across business units. For more on use cases, check out the Intersect Alliance website. https://www.snaresolutions.com/ Snare Enterprise’s premium features include: - Regulatory Compliance - TLS Encryption - Log Simulcasting - TCP – Guaranteed Log Delivery - USB Device Monitoring - And more!

glFlow is a robust, fast, portable, pcap-centric (D)DoS detection tool.

justniffer is a TCP sniffer. It reassembles and reorders packets and displays the tcp flow in a customizable way. It can log network traffic in web server log format. It can also log network services performances (e.g. web server response times) and extract http content (images, html, scripts, etc)

Automated Security Tools (autosec) aims to provide automatic tools which network administrators may use to help check and test the security of their network.

A tool to monitor internet hosts` bandwidth usage in a Linux-NAT network. A daemon collects data and clients display them (currently a Java applet with a graph). It automatically detects new hosts and has a nice summary statistic.

Originally written by Paul Vixie in 1986 and distributed through mod.sources, "display" is a program which will repeatedly execute a command and display the output through curses. The purpose of this project is to maintain and extend display.

Application Heartbeat Monitor is a daemon + library that applications register with to have their life signs monitored.

In digital visual effects we deal with an overwhelming number of images. Earth simplifies the management of this data by continuously tracking the whereabouts of image sequences across a filesystem or visual effects facility.

Echelog is a distributed system consisting of agents and one or more servers. Agents, distributed on computers over network, are monitoring the state of hosts and network. Collected data are sent to servers where they are processed and stored.

Free Agents DIDS is a distributed intrusion detection system that you place on each host on your network. Agents intercommunicate with aes encryption, automatically alert you, and secure your network for free!

Simple UPS monitoring plugin for GKrellM. Uses NUT (Network UPS Tools) for UPS connection. Based on "GKrellM Belkin UPS Plugin".

GSyslog is a graphic (transparent) syslog client for windows 2000 (w2k) and windows xp (wxp). It supports syslog relaying.

A - possibly - lightweight passive automation tool for Linux/POSIX systems

The 'Monitor' application, which consists of 2 parts, a MonitorServer (linux daemon) and a MonitorClient (java gui), will enable the user to monitor and log server process, memory, network and cpu information of multiple servers at a time.

The Looper Event / Alert System is an application primarily used for network management to perform alert monitoring and redirection. It is designed with extreme simplicity in mind and is highly modularized. Also used as a Netcool probe or gqateway.

NLAT is a tool that let you easily admin few tasks while logging in a Samba PDC, performing a set of operation you otherwise have to complete manually on each PC. NLAT is particulary useful in medium size and large size networks. The whole system is com

NeTAMS - Network Traffic Accounting and Monitoring Software. It is built for UNIX and works for networks with Cisco routers or PC Unix routers (Linux/FreeBSD/Solaris).

The goal of the project is to create a set of daemons that automate the contol over a cluster of machines. Check the Docs for a thorough description.
