SNMP Trap Translator is used to 'translate' traps received from the NET-SNMP / UCD-SNMP snmptrapd trap daemon into easy to understand messages. Git repository, downloads and support has been moved to https://github.com/snmptt/snmptt.

BASE is the Basic Analysis and Security Engine. It is based on the code from the Analysis Console for Intrusion Databases (ACID) project. This application provides a web front-end to query and analyze the alerts coming from a SNORT IDS system.

SIGAR (System Information Gatherer and Reporter) is a cross-platform, cross-language library and command-line tool for accessing operating system and hardware level information in Java, Perl and .NET.

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.

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.

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 can be used on embedded devices as well. It consists mainly of two programs: a collector, called monitorix, which is a Perl daemon that is started automatically like any other system service, and a CGI script called monitorix.cgi. Monitorix includes its own HTTP server built in (which is listening by default on port 8080/TCP) to see the statistics graphs, so you aren't forced to install a third-party web server to use it. Just point your browser at http://localhost:8080/monitorix.

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. In Norse mythology, Hugin and Munin are the ravens of the god king Odin. They flew all over Midgard for him, seeing and remembering, and later telling him. "Munin" means "memory".

Master/node to gather and graph "everything" on your systems using Tobi Oetiker's rrdtool. It can optionally warn your surveillance software. This software package was originally called LRRD. The project. Please see http://munin-monitoring.org/

Switchmap is a Perl program that creates HTML pages that show information about a set of Ethernet switches. It uses SNMP to gather data from the switches. Samples of Switchmap output can be found on the Project home page.

It collects the output of NagiosPlugins and generates graphs. Main features are: Getting values from nagios without patching, realtime graphing, automatic graphing of new services, easy to install

Cricket is a high performance, extremely flexible system for monitoring trends in time-series data. Cricket was expressly developed to help network managers visualize and understand the traffic on their networks, but it can be used all kinds of other job

WebInject is a tool for automated testing of web applications and web services. It can be used to test system components with HTTP interfaces, as a test harness to create a suite of functional and regression tests, or for service-level monitoring.

Integrate JBoss into Nagios monitoring through a small Collector MBean and a perl based Nagios plugin. Lets you read you and monitor JMX values from JBoss servers very efficiently. On the Nagios server no JDK or JBoss installation is needed.

Simple Event Correlator (SEC) is a lightweight event correlator for network management, log file monitoring, security management, fraud detection, and other tasks which involve event correlation.

FlowDoh is an NFSEN (nfsen.sourceforge.net) plugin that can... * Provide a real-time dashboard of the top-talkers on your network * Send email alerts based on network activity thresholds * Allow quick drill-down into detailed flow information * Record historical values so you can know if the network traffic is normal (Planned feature) FlowDoh can be used for multiple purposes: * Find hacked servers on your network * Identify users who are hogging bandwidth (such as peer-to-peer file-sharing) * Create a baseline of network statistics about your servers (planned feature) FAQ: Q: Why is it called FlowDoh? A: Because "'Doh!" is what you will say after installing FlowDoh and finding that some of your servers are already hacked. Another possible answer is this acronym: Flow-Dashboard-Of-Hogs.

netleak is a collection of small perlscripts that detects connectivity between network segments. It is mostly useful to detect "leaks" in large organizations that have private network segments physically separated from the Internet.
