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.

xloadtime

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

xloadtime is a extended version of xload. Originally written by Darren J Moffat. It provides a few enhacements over xload, namely:

An optional 12/24 hour clock
CPU bars on the left

Because this version used the old proc FS, this has been updated substantially to use the newer API for Linux. Subsequent changes also make this work across the BSDs.

Controlling xloadtime in terms of colours, etc., can happen via the Xresources database. For example:

xmemuse

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

xmemuse is a small memory monitor written by Harm Arts. It displays a scrolling chart of RAM and swap usage, reading statistics from /proc/meminfo.

Red shows used RAM, orange cached memory (including reclaimable slab), yellow buffers, green free RAM, blue used swap and white free or unavailable swap.

The chart height represents RAM plus the largest swap allocation observed.

xmm

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

xmm is a small memory monitor with a scrolling chart of RAM and swap usage. Its memory chart widget was written by Hans-Helmut Bühmann in 1996.

The chart uses brown for memory outside the active, inactive and free categories, red for active memory, yellow for inactive memory, green for free RAM and orange for used swap. Swap is drawn above the physical-memory total, with the chart rescaling as needed. Free RAM here means MemFree, not MemAvailable.

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.
