What is "gkrellm"

GKrellM (GNU Krell Monitors) is a system monitor software based on the GTK+ toolkit that creates a single process stack of system monitors. It can be used to monitor the status of CPUs, main memory, hard disks, network interfaces, local and remote mailboxes, and many other things.
