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

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.

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.

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.

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.

LCDproc controls various LCD and VFD devices in a standardized way, and ships with a client to display various system statistics. Supports multiple platforms (Linux, *BSD, Solaris). Client/server model allows multiple clients to use one display.

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

The Network Tracking Database (NetDB for short) tracks all changes to the MAC address tables on your switches and the ARP tables on your routers over time stored in MySQL. It supports extensive switch, VLAN and vendor code reports from a CLI or Web App. NetDB can generate CSV reports, track the usage of static IP addresses, record neighbor discovery data and much more. There is now a VM "appliance" with easier upgrades available in the Files section. See the http://netdbtracking.sourceforge.net for more details.

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.

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

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.
