The other (the slave one) first checks the status of the other server (a
simpel wget of the status page can be enough) and only sends out the alert
if
this page is not green.
So, basically, both servers are triggering on the same alert, but the
slave
server only sends out the alert if the primary server is not green.
Wouldn't there be more involved in this? What if the primary server's hobbit daemon was down, but the web service was still running? The secondary server would want to report the hobbit daemon being down, but wouldn't because the primary server's page was still green and hadn't been updated.

Malcolm
