procps is a package of utilities which includes ps, vmstat, top, w, skill, snice, pgrep, pkill, free, sysctl, pmap, uptime, and kill. These utilities report what is running, who is logged in, how long the system has been running, and what is using up memory. They can be used to kill processes and change run-time kernel configuration values.
The Linux joystick driver provides support for joysticks under Linux. The 1.2.14 version supports classic analog PC joysticks, ThrustMaster FCS, CH Flightstick Pro and 6/8- button gamepad compatible extensions, digitally communicating joysticks from Creative, FPGaming, Genius, Gravis, Logitech, MadCatz, Microsoft, SpaceTec, ThrustMaster, PDPI L4 gamecard, as well as various (NES, SNES, Sega, PSX, Atari, Amiga, Commodore, Amstrad) gamepads and joysticks connected to the PC's parallel port.
gpppkill is a program for Linux that ends a ppp connection if it doesn't receive a minimal amount of bytes during certain time. It shows a bar plot according to the amount of bytes received per second. All resident ppp daemons are recognized and gpppkill lets you choose which one to kill. It is written in C++ using the GTK+ toolkit.
The Advanced Linux Sound Architecture is composed of several parts. The first is a fully modularized sound driver which supports module autoloading, devfs, isapnp autoconfiguration, and gives complete access to analog audio, digital audio, control, mixer, synthesizer, DSP, MIDI, and timer components of audio hardware. It also includes a fully-featured kernel-level sequencer, a full compatibility layer for OSS/Free applications, an object-oriented C library which covers and enhances the ALSA kernel driver functionality for applications (client/server, plugins, PCM sharing/multiplexing, PCM metering, etc.), an interactive configuration program for the driver, and some simple utilities for basic management.
Netwatch allows a user to monitor an Ethernet segment or PPP line and examine activity on the network. Hostnames are highlighted in colours to indicate activity on the bus network based on time. The monitor includes statistics on transmitted and received packets, transmitted and received bytes, protocol of last packet (TX or RC), last communication partner (IP address) and Logging entire stats to an ASCII file. There is a TOP mode which allows a sorted list of hosts based on IP usage. All info is updated on a per second basis.
Moodss is a modular monitoring application, which supports operating systems (Linux, UNIX, Windows, etc.), databases (MySQL, Oracle, PostgreSQL, DB2, ODBC, etc.), networking (SNMP, Apache, etc.), and any device or process for which a module can be developed (in Tcl, Python, Perl, Java, and C). An intuitive GUI with full drag'n'drop support allows the construction of dashboards with graphs, pie charts, etc., while the thresholds functionality includes emails and user defined scripts. Monitored data can be archived in a SQL database by both the GUI and the companion daemon, so that complete history over time can be made available from Web pages or common spreadsheet software. It can even be used for future behavior prediction or capacity planning, from the included predictor tool, based on powerful statistical methods and artificial neural networks.
LCDproc is a utility to drive one or more LCD (and LCD-like) devices attached to a host. It is comprised of a server, which uses a modular device driver system to control attached displays, and one or more clients to gather data as appropriate and send screen data to the server. The included client displays a multitude of system statistics (CPU/memory/disk usage, uptime, date and time, temperature, etc.). Multiple clients can connect to the server simultaneously, and clients can set priorities on the screens they provide to influence in what order items are displayed. This facility can also be used to "pop" critical screens (such as an entry from syslog from a log-watching client). All functionality is implemented in userland. Support for many display devices and several platforms (Linux, *BSD, and Solaris at least) is included.
mon is a tool for monitoring the availability of services and sending alerts on prescribed events. Services are defined as anything tested by a "monitor" program, which can be something as simple as pinging a system, or as complex as analyzing the results of an application-level transaction. Alerts are actions such as sending email, making submissions to ticketing systems, or triggering resource fail-over in a high-availability cluster.
