I saw the the interesting slides from the presentation at Sophiaconf,
I used these command shinken-discovery -c etc/discovery.cfg --db Mongodb -m 'NMAPTARGETS=XXX.XXX.XXX.XX'
to add the discovered host directly on Mongodb.

The problem is that the script create the host on the collection "discovered_hosts" not on "hosts".
Is there an other script to launch to validate the discovered host like ?
