Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I have a computer that monitors some servers. I would like to connect a device to the computer that can be turned on (like a siren or police light) when some anomalies are detected on the server. Essentially - I'd run a script to turn on the device and then power it off.

Thanks!

To those voting to migrate. I don't believe this is a better fit for superuser. Having an out-of-band notification system is something many system administrators may find useful. –  Zoredache Oct 2 '10 at 6:31

X10 Serial -> relay/power control

Alternatively, power strip that is IP accessible and controllable via SNMP or Telnet with an expect script. APC makes one that is fairly workable that we use for a stonith handler.

D to A converter, allows you to control a relay attached to the serial port.

Sparkfun makes a USB relay.

Arduino boards can be handy

There many devices designed for notifying deaf/hard-of-hearing people when an incoming phone has been made. Many would allow you to setup indicator light anywhere you have an analog phone line. All you need is a modem on your monitoring system to call the number.

If you get a voice modem on your monitoring system you may be also able to have it call and leave you a message on a cell phone in case the network is down.

Do not underestimate the value of scrolling LED sineage! A lot of those signs are USB connectable which allows you to program their messages on the fly. Handy for indicating which widget is on the blink.

Any recommendations for LED sineage? –  user55929 Oct 2 '10 at 8:30
    
@Mark I haven't bought any myself, but other departments at work have used them. I can't recommend anything in any meaningful way. The google term "scrolling LED signs" will bring buckets of hits. –  sysadmin1138 Oct 2 '10 at 8:33
