Problem to check logs with Hobbit

[L.M.J]

Hello,

  I've posted a couple of month but after hours & hours of tests, I still
can't check logs with Hobbit. I'm running a Hobbit server on Linux Ubuntu
and a Hobbit client with 'client side configuration' on Ubuntu or RHEL.

On my client computer called "Suspendisse" : 
    $ cat localclient.cfg
       ...
       # LOG
       LOG /var/log/messages MARK COLOR=RED
       ...
    $

For this example, I will go get a red alert when a "MARK" 
Then, on my Hobbit server called "Fusce" :
    $ cat hobbit-clients.cfg
       ...
       HOST=Suspendisse
       LOG /var/log/messages MARK COLOR=RED
       ...
    $

  That's what I've read on the Hobbit man page but it doesn't work. The log
doesn't appear on my Hobbit web pages. What I'm doing wrong ?

  Thanks by advance,
