The Bubbling Load Monitor (or "Bubblemon" for short) is a system load monitor for the GNOME panel. It looks like a vial containing water. The water level indicates how much (electronic) memory is in use. The color of the liquid indicates how much swap space is used. The amount of bubbles reflects the system CPU load. A message in a bottle indicates there is unread mail. A reed-like graph shows I/O load. On multi-core systems the CPU with the highest load will bubble in the middle, and the others on the sides, so it's possible to see how well load gets distributed between CPUs.
GWCC allows users to execute network utilities (ping, nslookup, traceroute), workstation commands (netstat, df, lpr), and do cool things like process grep from a single tabbed window. Command flags are highly configurable, results windows are savable and printable, and there is a System Stats tab showing you process info, current users, Apache server status, Samba status, and more.
Gnetload is a GNOME applet showing the network load of a specified network interface in a histogram. It is highly configurable; configuration options include different colors for incoming and outgoing traffic, fixed or dynamic histogram scaling, and textual representation of the current network load.
Band Saw is a syslog monitoring program for GNOME. It allows the user to define filters that specify which log messages should be drawn to the user's attention. Combined with syslog's remote logging functionality it provides an effective, scalable, and easily deployed monitoring solution.
gtkShots is a GUI tool to automatically save screenshots at regular or scheduled points in time. with the Options may be chosen for each screenshot to be saved, such as the size, the parent folder, and the time interval between them. Some possible applications include the creation of presentations or monitoring desktop activity. gtkShots includes pyshots, the command-line program that actually implements its functionality.
