Measuring Blackouts with Cacti

Every zero point on this graph — which represents the last two months of uptime on my laser printer (!) — is the result of a blackout.

The first was kind of disappointing. The rest have just been annoying: Getting up late with 05:14 flashing on the alarm clock, asking Pipka to set the time on the microwave (because I can’t figure it out — seriously) and working out which other devices didn’t manage to start properly…

Printer Uptime Cacti Graph

This is where technology fails us. Not because the lights went out, but because there were only about thirty seconds between, “Huh, I bet the SNMP thingy in the printer can tell me its uptime” and having it beautifully graphed with Cacti.

… and now because I can see my laser printer’s uptime, I care about my laser printer’s uptime.

Well, I would. If it had any.

Update: It should be noted (mainly for California readers) that blackouts are an odd occurrence here.

  1. Time to invest in a new battery for your alarm clock, and a UPS or two for your printer/network/microwave/tamagotchi/etc :-)

  2. I’ll never get uptimes like this, since I’m in Germany and we’re supposed to be environmental friendly and power electronics off when we don’t need them. ;)

  3. Benjamin: some of us need to keep our computers on so we can feed our cats when we are away.

    Joel: laser printers on UPS are bad. Something to do with the current spike from the toner heater? Dunno about inkjets.

  4. I have the exact opposite problem. With my old apartment’s crappy wiring, I get long brownouts every time my laser printer starts up (scattered a few $50 UPSes around and everything is fine but still, a bit worrisome).
