Pandora FMS is software for monitoring computer networks. Pandora FMS allows monitoring in a visual way the status and performance of several parameters from different operating systems, servers, applications and hardware systems such as firewalls, proxies, databases, web servers or routers.
The history of free and open-source software begins at the advent of computer software in the early half of the 20th century. In the 1950s and 1960s, computer operating software and compilers were delivered as a part of hardware purchases without separate fees. At the time, source code—the human-readable form of software—was generally distributed with the software, providing the ability to fix bugs or add new functions. Universities were early adopters of computing technology. Many of the modifications developed by universities were openly shared, in keeping with the academic principles of sharing knowledge, and organizations sprung up to facilitate sharing.
The GNU Affero General Public License is a free, copyleft license published by the Free Software Foundation in November 2007, and based on the GNU GPL version 3 and the Affero General Public License (non-GNU).
SplendidCRM produces open source Customer Relationship Management (CRM) software developed in C# for the ASP.NET framework. The product is available in two editions - Open Source and Professional - the main difference between the two products is the inclusion of stored procedures and source code for a MS Outlook 2003/2007 plug-in in the Professional edition.
The GNU General Public Licenses are a series of widely used free software licenses, or copyleft licenses, that guarantee end users the freedoms to run, study, share, and modify the software. The GPL was the first copyleft license for general use. It was originally written by Richard Stallman, the founder of the Free Software Foundation (FSF), for the GNU Project. The license grants the recipients of a computer program the rights of the Free Software Definition. The licenses in the GPL series are all copyleft licenses, which means that any derivative work must be distributed under the same or equivalent license terms. It is more restrictive than the Lesser General Public License and even further distinct from the more widely-used permissive software licenses such as BSD, MIT, and Apache.
Shinken is an open source computer system and network monitoring software application compatible with Nagios. It watches hosts and services, gathers performance data and alerts users when error conditions occur and again when the conditions clear.
NetBSD is a free and open-source Unix-like operating system based on the Berkeley Software Distribution (BSD). It was the first open-source BSD descendant officially released after 386BSD was forked. It continues to be actively developed and is available for many platforms, including servers, desktops, handheld devices, and embedded systems.
isyVmon was a computer system and network monitoring software application system created by iT-CUBE SYSTEMS. It was designed to monitor and track the status of various applications, network services, servers, and other network hardware.
NConf is an open source tool for configuring the Nagios network monitoring system. It is mainly targeted at sysadmins who are looking for a more convenient way of managing their Nagios configuration files through the use of a graphical user interface, as opposed to maintaining the configuration files with a text editor.
Icinga is an open-source computer system and network monitoring application. It was created as a fork of the Nagios system monitoring application in 2009.
Univention Corporate Server (UCS) is a server operating system derived from Debian with an integrated management system for the central and cross-platform administration of servers, services, clients, desktops and users as well as virtualized computers operated in UCS. In addition to the operation of local, virtual instances, UCS can also be operated in cloud environments. Via the integration of the open source software Samba 4, Univention also supports the functions provided in many companies by Microsoft Active Directory for the administration of computers operated with Microsoft Windows. UCS-based components and UCS-certified, third-party products can be installed via the Univention App Center. UCS provides all App Center applications with a runtime environment and services for the operation including a central, consistent management of the apps. Docker containers can also be run on UCS systems and several of the apps available in the App Center are Docker-based.
Proxmox Virtual Environment is a virtualization platform designed for the provisioning of hyper-converged infrastructure.
Naemon is an open-source computer system monitoring, network monitoring and infrastructure monitoring software application. Naemon offers monitoring and alerting services for servers, switches, applications, and services. It alerts the users when things go wrong and alerts them a second time when the problem has been resolved. Naemon was created in 2014 as a fork of Nagios.
