libmnl is a minimalistic user-space library for Netlink developers. There are a lot of common tasks involved in parsing, validating, and constructing both the Netlink header and TLVs that are repetitive and easy to get wrong. This library aims to provide simple helpers that allow you to re-use code and avoid re-inventing the wheel.
Lilith is a logging and access event viewer for the Logback logging framework. It has features comparable to Chainsaw, a logging event viewer for log4j. This means that it can receive logging events from remote applications using Logback as their logging backend. It uses files to buffer the received events locally, so it is possible to keep vast amounts of logging events at your fingertip while still being able to check only the ones you are really interested in by using filtering conditions.
NTMF is a C++ framework for developing software that requires the manipulation of packets traversing a system. The main application areas are protocol testing, protocol implementation testing, network emulation, and network monitoring. It has support for link level packet capturing (using libpcap), link level packet injection, and network level packet injection for IPv4 packets (using lipnet). It supports multi-threaded execution, provides thread-safe packet queues, and provides a dynamic Finite State Machine representation.
NetOculus is a network monitoring system that provides all the functions of the well-known monitoring system MRTG. It also has a number of its own benefits. It can automatically monitor any kind of detectable alteration in a computer network (and in relatively separated network areas). It can efficiently notify staff about hardware state changes. Analytical information is aggregated. Specific pieces of hardware are associated with the staff members who responsible for them. The solutions for solved problems are reported to the staff for further use.
