Hobbit is the successor to the bbgen toolkit, which has been available as an add-on to Big Brother since late 2002. The name change was decided upon when Hobbit acquired enough functionality to be a stand-alone product. The tools that formed the bbgen toolkit are still present in Hobbit and are quite important for it, so if you have used bbgen before, Hobbit will seem quite familiar. Hobbit monitors your hosts, your network services, and anything else you configure it to do via extensions. Hobbit will periodically generate requests to network services - http, ftp, smtp and so on - and record if the service is responding as expected. Through the use of agents installed on the servers, you can also monitor local disk utilisation, logfiles and processes.
