Monitor a Linux Box With Machine Generated Music 114

mcappel writes "Linux and Unix admins are familiar with vmstat and top, which are visual tools displaying the health of a computer. chordStats adds a new interface to a system monitoring setup — information passed through tone, timbre, and harmony. IBM's Nathan Harrington, who wrote Knock Some Commands Into Your Laptop, created a simple Perl script to send note events to FluidSynth that forces various system events to be interpreted as a part of a harmonious interval, and looks at options for enhancing a musical system monitor."

    Back in the "old" days, we had techs that could tell you the error/fault that had occurred by the sound pattern produced by the line printers. To the very last one, they were upset/angry when the printers where replaced with quieter versions as this now meant they had to look up from playing solitaire/day trading to actually look if there were any significant events.

    • Yeah, my dad's store recently got rid of two of three dot matrix printers, which did the same thing. When an order came in, it was deet-deet-doot-doot, deet-deet-doot-doot, dee-doot-doot if everything was printing properly. If it didn't, you could really tell because the pitch would be off (e.g. paper not straight made it lower).

      Now, however, it's a laser printer which merely hums when active, and beeps once and flashes lights on errors. If you're out back, you can't hear it.
