PowerKey Pro with the Server Restart Option from Sophisticated Circuits is a hardware power controller for Macs. You only need this Plug-In if you are using the PowerKey Pro hardware to monitor your server, detect system crashes and automatically restart the machine.
You can set up a PowerKey Event to track a timer, and restart the computer when it runs out. The WebSTAR PowerKey Pro Tickler sets the User Timer to 5 minutes at one-minute intervals. Once set, the User Timer starts counting down to zero. As long as WebSTAR is running, the Plug-In will continue to reset the User Timer, so it will never reach zero.
If the User Timer ever actually reaches zero, it means that WebSTAR has stopped resetting it, usually due to a crash or freeze. PowerKey Pro will then execute the "When Timer Expires" Event. This will restart the system and restore WebSTAR to normal operation.
If you do not have PowerKey Pro installed, you will see error messages in the Status Window Web Monitor pane. Remove the WebSTAR PowerKey Pro Tickler file from the Plug-Ins folder and restart the server to avoid spurious restarts.
