NConf is a PHP based web-tool for configuring the Nagios monitoring software. It differs from similar tools by offering enterprise-class features like templates, dependencies and the ability to configure a large-scale, distributed Nagios topology.

Nagstamon is a Nagios status monitor which resides in systray or desktop (Linux, macOS, Windows) as floating statusbar to inform you in realtime about the status of your hosts and services. It allows to connect to multiple Nagios based monitors. Currently supported are Nagios, Icinga, Opsview, Op5 Ninja, Check_MK Multisite, Centreon and Thruk.

FlowViewer provides a convenient web-based user interface to Mark Fullmer’s flow-tools suite and CMU's netflow data capture/analyzer, SiLK. The inclusion of the underlying SiLK tool set enables FlowViewer users to continue to use the tool with the newer IPFIX netflow data protocol, which includes support for IPv6 and Cisco's v9 and FNF netflow. FlowViewer has been developed for NASA’s Earth Sciences Data and Information System (ESDIS) networks, and credit goes to NASA for their usual outstanding support of innovation. The FlowViewer tools provide additional graphing and tracking features by utilizing open source software including Thomas Boutrell’s gd, Lincoln Stein's GD, Martien Verbruggen's GD::Graph, and Tobias Oetiker’s RRDtool. FlowViewer v4.6 fixes non-UTC local time environments for FlowViewer and FlowGrapher, and $no_devices_or_exporters FlowMonitor_Collector problem. **Note: SiLK must be v3.8.0 or later. Version 3.9 handles sFlow data.

AutoMeter is a X11/Xt/Xaw application scanning and representing Linux (tm) /proc/* and more metrics in a automatically optimal scalling Athena Widget, called AutoScale. AutoScale is full color and has many representation options.

BigPlg allows the collection of the IPv4 Internet routing table which may be viewed by service providers and/or ISP customers to validate IP routing across autonomous systems. Routing updates may also have attributes aliased to become (graph) readable. This function exists to allow the exporting of RIB updates to Splunk, or any such data collector. A beneficial side-effect of collecting BGP routing information is the ability to track BGP updates/events local or remote(upstream). To analyze events Splunk is supported. A JSON/Socket API is currently under development. Custom graphs can be easily implemented if taken the time to do so. There's certainly no need to rely on Splunk if one developed another way of displaying data. This project is meant to be nothing more than a route collector, and it's interface is solely CLI(command line interface). This project does not have graph data "out of the box".
