avrmon-stk200 is a port of Denis Chertykov's Linux debug monitor system for Atmel AVR microcontrollers. It is compatible with the connection scheme used in Atmels "STK200 Starter Kit", as opposed to the original version that used the "DAPA" (Alex's Direct Avr Parallel Access) scheme. In short, the monitor system allows you to do in-systems source-level debugging on AVR microcontrollers with gdb (avr-gdb).

interceptty is a program that sits between a serial port (or other tty-style device) and an application, and logs everything that passes through it. It is designed to let you see exactly what's going to your serial port. It can also act as a logging serial-to-Ethernet client or server.
SysOrb is a client/server package that can monitor servers remotely (such as Web servers), or monitor devices on servers (such as disks, memory, load, etc.). It will alert the administrators via e-mail or pager if a server is entering a critical condition, and has its own database backend, allowing for massive collection of system statistics.
