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.

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.

The tool offers you end-to-end views of your storage environment including LAN and SAN and can save you significant money in operation monitoring and by predicting utilization bottlenecks in your virtualized environment. You can also generate policy-based alerts, view overall health status of your systems, reduce service downtime, use capacity and forecasting data - Real-time storage performance visibility in LAN and SAN multi-vendor environment - Historical reporting (graph, CSV, PDF) - Alerting based on performance thresholds - Storage event monitoring The tool supports enterprise class level storage devices from major storage vendors like: IBM, Dell EMC, NetAPP, HPE, Hitachi, Lenovo, Pure Storage, Huawei, Dot Hill, INFINIDAT, Fujitsu, DataCore, Quantum, QNAP, FalconStor,Ceph, Synology, RAIDIX, Qumulo,Inspur,Veritas Monitoring of the SAN supports Brocade, Qlogic and Cisco SAN switches Monitoring of the LAN network Try demo at http://demo.stor2rrd.com

OSSIM, AlienVault’s Open Source Security Information and Event Management (SIEM) product, provides event collection, normalization and correlation. For more advanced functionality, AlienVault Unified Security Management (USM) builds on OSSIM with these additional capabilities: * Log management * Advanced threat detection with a continuously updated library of pre-built correlation rules * Actionable threat intelligence updates from AlienVault Labs Security Research Team * Rich analytics dashboards and data visualization

A network access control (NAC) system featuring a captive-portal for registration and remediation, wired and wireless management, 802.1X support, isolation of devices, integration with IDS; it can be used to secure networks from small to large.

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.

Webminstats is a Webmin's module which display a graphical log of historic information. It's modular in design, as to be able to log everything from CPU usage to email box size.

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.

Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and Grids. It is based on a hierarchical design targeted at federations of clusters. Supports clusters up to 2000 nodes in size.
