Open Source Perl Networking Software for Linux

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.

FAST library for storing and displaying various types of statistics. Rock stable and robust and well-designed image output.

FwPlatinum provides real time data analysis of CheckPoint FireWall-1 connection logs. Data is stored for up to 2 years, and is accessed by CGI generated graphs which can drill down to the specific time that you are interested in.

Savors is a visualization framework that supports the ingestion of data streams created by arbitrary command pipelines. Any number of data streams can be shown synchronized by time in the same or different views, which can be arranged in any layout. These capabilities combined with a powerful parallelization mechanism and interaction models already familiar to administrators allows Savors to display complex visualizations of data streamed from many different systems with minimal effort.

TraffStats: network Traffic Statistic - is a monitoring and traffic analysis software, using SNMP to collect data from any enabled device. - has the ability to generate graphs (using jpgraph) with the option to compare and sum up different devices.

VisualNMS is a network management system with powerful visualisation features due to its vectorial based rendering (SVG). It is built using perl, javascript, SVG, HTML. It includes Layer 2 autodiscovery based on LLDP and other discovery protocols (Cisco's CDP, Extreme Networks' EDP, etc.). Other features include: real time SVG graphs on links, web2cli engine (AJAX to Telnet/CLI), editable maps, auto layout (based esentially on GraphViz), VLAN mapping (work in progress) based on SNMP.

Set of tools and libs for managing structured data in a very flexible way: Imp./Exp. ASCII, XML, SQL, PS, Tex/LaTex, RTF GUI: X-Windows, MS-Windows Interface to C++, DBs, Perl, PHP, Java, TCP/IP LISP-like interpreter written in C++ using C-LIB

Sarparse is a utility based off of cacti to graph Sar metrics from remote hosts. It require NRPE and SAR to run out-of-the box but could easily be modified for any other transport.
