True. It definitely is important to have a close look at the system that 
you are performing the health check on.

We are running a php based cms and are running a health check on a small 
script. That script is testing if there is an active db, if the 
rendering engine of the cms is responding and if everthing is fine. it 
is returning a "1". If not, it will exit and the probe fails, rendering 
the backend as sick.
