The sniffy project can trace/log the data of any pseudo terminal in the system. Due to the way the terminal works, such a terminal trace provides complete information of what happened on the terminal screen, and sniffy is able to display/replay this information. It consists of a kernel module able to connect/hook on the pseudo terminal, a program to display the contents of any pseudo terminal on the fly, a daemon process tracing the pseudo terminal content into the file, and a replay program to replay any stored pseudo terminal session.
The i2c-tiny-usb is a open source/open hardware project. It is meant to replace those i2c printer port interfaces often used to connect i2c sensor chips (e.g. temperature sensors) to a Linux PC. It is fully documented and based on cheap and easy to obtain hardware. It comes with a Linux kernel driver, and can thus re-use existing Linux i2c client chip drivers. It additionally comes with a libusb-based demo application that also works under Windows and Mac OS.
DMAring demonstrates a novel generic network interface card driver architecture which works in hybrid interrupt-polling mode to deliver superior real-time performance on Linux, Red Hat Linux, or Linux-RTAI-LXRT (a real-time co-kernel for Linux with user level extension). Existing Linux drivers saturate the CPU at a much lower packet rate than the maximum possible wire line packet rate, but this driver allows vanilla network cards to be used for high speed packet capturing.
Systemtap is a GUI to assist in the development of Systemtap scripts and to graph the return values of those scripts. It is intended to ease the use of the Systemtap tool for Linux. It is both an IDE for the scripting language and a data visualization and analysis tool. The GUI is targeted at system administrators who want to get information out of their system using Systemtap, as well as developers who wish to write new scripts. It is an Eclipse-based application.
mpt-status is a query tool for accessing the running configuration and status of LSI SCSI HBAs. It is a heavily modified version of the original mpt-status-1.0 tool written by Matt Braithwaite. It allows you to monitor the health and status of your RAID setup. Currently supported and tested HBAs are the LSI 1030 SCSI RAID storage controller and LSI SAS1064 SCSI RAID storage controller. Since the tool uses the MPI (message passing interface), chances are high that the basic information regarding RAID status will be available for all LSI-based controllers.
