We had an outage last week I think, can't remember officially around half an hour but sure it was more as I got fed up and went to bed... Why I am mentionning is that it looks very similar, Swisscom had a router etc maintenance where no disruption was expected, finally maybe a third (if not a half...) of Switzerland was without TV phones using swisscom box and no 4G... many 24/24 alarm (police/hospitals...) were out of order... In other words a net issue that propagated bringing the whole datacenter down

wmmemload - A dockapp to monitor memory/swap usages SYNOPSIS
wmmemload [options] DESCRIPTION
This manual page documents briefly the wmmemload command. WMMemLoad is a program to monitor memory/swap usages. It is a dockapp that is supported by X window managers such as Window Maker, After- Step, BlackBox, and Enlightenment. The current memory usage is displayed in the top half. The swap usage is in the bottom half. It has an LCD look-alike user interface. The back-light may be turned on/off by clicking the mouse button over the appliacation. If the usage hits a certain threshold, an alarm-mode will alert you by turning on back-light. OPTIONS
This program follows the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below. -d, --display <string> Attempt to open a window on the named X display. In the absence of this option, the display specified by the DISPLAY environment variable is used. -bl, --backlight turn on back-light. -lc, --light-color <color> back-light color. (rgb:6E/C6/3B is default) -i, --interval <number> number of secs between updates. (1 is default) -b, --ignore-buffers ignore buffers. (GNU/Linux) -c, --ignore-cached ignore cached pages. (GNU/Linux / FreeBSD) -wr, --ignore-wired ignore wired pages. (FreeBSD) -h, --help show help text and exit. -v, --version show program version and exit. -w, --windowed run the application in windowed mode -bw, --broken-wm activate broken window manager fix -am, --alarm-mem <percentage> activate alarm mode of memory. <percentage> is threshold of percentage from 0 to 100.(90 is default) -as, --alarm-swap <percentage> activate alarm mode of swap. <percentage> is threshold of percentage from 0 to 100.(50 is default) AUTHOR
