If you just want to determine if specific processes are running, this is a 
built-in feature (if you have the hobbit client installed on the hosts you are 
interested in). See hobbit-clients.cfg

Depends on what aspects you are monitoring, and how you have set things up.

By default, the clients will send data to the server at the intervals 
specified in the 'client' task in the clientlaunch.cfg file.

However, you can enable the msgcache task on the client, and configure the 
client to send the data to itself (getting to msgcache), and then hobbitfetch 
(which you need to enable on the server) will pick up the data (if you have 
the pulldata tag in bb-hosts for that host).

'man bb'.

You mean the hobbit client?
