If a device has relays we should control them!

Last week I wrote about monitoring, logging, graphing and alerting on a ControlByWeb temperature module's readings. What I left out was that the module in question also has two relays.

And, if a device has relays, we should do something with them!

Since Xymon is our monitoring solution of choice I wrote a bash shell script that may be called as an alert script for Xymon to turn on, off, pulse or toggle a relay for a specific alert.

Take a look at http://www.revpol.com/xymon_cbw_relay_script to see how a Xymon monitoring server can be configured to control a ControlByWeb module's relays.
