heartbeats

[Chris Miles]

Hi Yves,

You could try using EDDIE Tool's PORT directive to periodically make TCP 
connections to your clients and check the result matches what is 
expected.  The alert engine will make it easy for you to define actions 
to perform for failure conditions.

You could also do actual (icmp) pings and/or HTTP requests from it also, 
if that helps.

Cheers,
Chris
