Netdata is a well-crafted real time performance monitor to detect anomalies in your system infrastructure. Visualize many types of data including disk activity, SQL queries, website visitors and more. This tool is useful to monitor linux servers.

Osquery is an operating system instrumentation framework for Windows, OS X (macOS), Linux, and FreeBSD. The tools make low-level operating system analytics and monitoring both performant and intuitive. Osquery exposes an operating system as a high-performance relational database. This allows you to write SQL queries to explore operating system data. With osquery, SQL tables represent abstract concepts such as running processes, loaded kernel modules, open network connections, browser plugins, hardware events or file hashes.Osquery queries your devices like a database. Osquery uses basic SQL commands to leverage a relational data-model to describe a device. Frequently, attackers will leave a malicious process running but delete the original binary on disk. This query returns any process whose original binary has been deleted, which could be an indicator of a suspicious process.

tcpick is a textmode sniffer; it tracks tcp streams, shows the status, reassembles and saves the data captured in files or displays them in the terminal in different modes (ascii, hex..). There is a color-mode. Useful to get files passively.

dvbsnoop - DVB analyzer / MPEG analyzer program to monitor, analyze, debug, dump or view dvb/mpeg/dsm-cc/mhp stream information (TS, PES, SECTION) (e.g. digital television) send via satellite, cable or terrestrial.

The fetchlog utility displays the last new messages of a logfile (syslog). fetchlog is similar like tail but offers some extra functionality like pattern matching with regular expressions, output formatting for email, SMS, pager or SNMP tools, etc.

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.

Automated network based hard disk drives / storage devices erasure is server based software which installs on a central server. Server is connected to network switches and several PXE boot enabled workstations are attached to the network. As soon as the workstation is powered on, it boots off the network via the server and begins wiping all the attached hard disk drives. Once all the hard drives are wiped, data related to each hard disk is stored in the central server’s database.

Hyperic is application monitoring and performance management for virtual, physical, and cloud infrastructures. Auto-discover resources of 75+ technologies, including vSphere, and collect availability, performance, utilization, and throughput metrics.

Fail2Ban monitors log files like /var/log/pwdfail or /var/log/apache/error_log and bans failure-prone addresses. It updates firewall rules to reject the IP address or executes user defined commands. Please see code and download from https://github.com/fail2ban/fail2ban . SF Fail2ban portal might not be up-to-date

pcapsipdump is libpcap-based SIP sniffer with per-call sorting capabilities. It writes SIP/RTP sessions to disk in a same format, as "tcpdump -w", but one file per SIP session (even if there is thousands of concurrent SIP sessions). Getting started: http://pcapsipdump.sf.net/

A bandwidth meter, for monitoring internet connection speeds and usage.

A console-based program to handle MTA (postfix,exim) queues interactively

360-FAAR (Firewall Analysis Audit and Repair) is an offline, command line, firewall policy manipulation tool to filter, compare to logs, merge, translate and output firewall commands for new policies, in Checkpoint dbedit, Cisco ASA or ScreenOS commands, and its one file! Read Policy and Logs for: Checkpoint FW1 (in odumper.csv / logexport format), Netscreen ScreenOS (in get config / syslog format), Cisco ASA (show run / syslog format), 360-FAAR compares firewall policies and uses CIDR and text filters to split rulebases / policies into target sections and identify connectivity for further analysis. 360-FAAR supports, policy to log association, object translation, rulebase reordering and simplification, rule moves and duplicate matching automatically. Allowing you to move rules to where you need them. Build new rulebases from scratch with a single 'any' rule and log files, with the 'res' and 'name' options. Switch into DROPS mode to analyse drop log entries.

This is a set of perl and php scripts that are used to collect, process, store and display netflow data.

Show system and ISDN information on external liquid crystal displays

nload is a console application which monitors network traffic and bandwidth usage in real time. It visualizes the in- and outgoing traffic using two graphs and provides additional info like total amount of transfered data and min/max network usage.

Output spool reader for Snort! This program decouples output overhead from the Snort network intrusion detection system and allows Snort to run at full speed. It takes input and output plugins and can therefore be used to convert almost any spooled fil

Serverstats is a simple tool for creating graphs using rrdtool. Serverstats does not have any features to manage the created rrd-files, if you change anything you have to delete and recreate the files. Perhaps you can avoid this using third-party-tools

Count traffic from users with dynamic ip addresses. Uses information from application level (Samba, pppd, etc.) to operate on network level (modify ipfw or another firewall rules for traffic counting).
