fping is a program to send ICMP echo probes to network hosts, similar to ping, but much better performing when pinging multiple hosts. fping has a very long history: Roland Schemers did publish a first version of it in 1992 and it has established itself since then as a standard tool for network diagnostics and statistics. There was no official fping release from 2002 until end of 2011. Various patches existed, but were never integrated "upstream". Also, the official maintainer didn't answer emails, so I decided to just step up and take over maintenanceship.To mark this change of maintenance, and avoid confusion, I decided to call it version 3. Besides a new maintainer, fping now also features a completely rewritten main loop implementation which improves performance significantly. The run time is now close to the theoretical time required to send and receive the pings under the specified parameters.

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.

The primary goal of the Network UPS Tools (NUT) project is to provide support for Power Devices, such as Uninterruptible Power Supplies, Power Distribution Units, Automatic Transfer Switches, Power Supply Units and Solar Controllers. NUT provides a common protocol and set of tools to monitor and manage such devices, and to consistently name equivalent features and data points, across a vast range of vendor-specific protocols and connection media types. Network UPS Tools (NUT) is an open-source solution for monitoring and managing uninterruptible power supplies (UPS) and other power devices across networks.

AirSnort is a wireless LAN (WLAN) tool which cracks encryption keys on 802.11b WEP networks. AirSnort operates by passively monitoring transmissions, computing the encryption key when enough packets have been gathered.

Switch Miner is a lightweight utility for Windows that acts as a switch port mapper/switch port discovery tool for Cisco switches. It helps network engineers discover the devices that are connected to the all the ports of a switch. It will even discover neighboring switches via CDP and scan them also. Using SNMP it scans switches and creates excel xlsx or csv files. What Does Switch Miner Discover? Interface Info (Name/Last Change) Speed and Duplex (Operational/Admin) MAC Addresses OUI Manufacturer VLAN Number (Data/Voice) VLAN Name (Data/Voice) IP Addresses DNS/NBT Computer Names User Info Domain Info Interface Errors CDP Neighbor Info

ntopng is a tool for both Unix and Win32 that shows the network usage, similar to what the popular top Unix command does. It sports a web interface for accessing accounting data and includes support for popular tools/protocols as well DPI and host categorisation.

Performance Co-Pilot (PCP) provides a framework and services to support system-level performance monitoring and management. It presents a unifying abstraction for all of the performance data in a system, and many tools for interrogating, retrieving and processing that data. PCP is a feature-rich, mature, extensible, cross-platform toolkit supporting both live and retrospective analysis. The distributed PCP architecture makes it especially useful for those seeking centralized monitoring of distributed processing.
