xcpustate

Mon, 01 Jan 0001 00:00:00 +0000

xcpustate displays CPU activity as coloured bars, with one bar per logical CPU on Linux. It was originally written by Mark Moraes to monitor a Silicon Graphics Iris 4D/240, and later maintained by John DiMarco. Its copyright dates back to 1988; the version preserved here is 2.9 from 2006.

This version includes fixes for modern compilers, RPC libraries and Linux CPU/disk statistics.

The default CPU colours are:

Blue: idle, including I/O wait.
Green: user programs.
Yellow: programs running with a positive nice value.
Red: system time, including interrupts and virtual-machine steal time.

xsysinfo

Mon, 01 Jan 0001 00:00:00 +0000

xsysinfo is a system monitor written by Gabor Herr. It displays horizontal bars for the one-minute load average, CPU idle time, memory and swap usage. The load bar is divided into segments as the load increases; CPU idle includes I/O wait and is measured across all CPUs.

The screenshot uses the supplied colour resources:

XAPPLRESDIR="$PWD/" ./xsysinfo -xrm '*customization: -color'

With these resources, the memory segments show other used RAM in a tomato colour, shared memory in green and buffers/cache in orchid. Unfilled space is free RAM; the swap bar shows the proportion used.
