nova-compute on each compute node sends a regular message to the
nova-scheduler on the scheduler node with an update of its status. These
are saved into that table. You can see these updates in your log:

2012-08-06 17:25:59 DEBUG nova.scheduler.host_manager
[req-4549b72e-83e5-4617-9a6b-81c17609c83e None None] Received compute
service update from molokai. from (pid=5003) update_service_capabilities
/usr/lib/python2.7/dist-packages/nova/scheduler/host_manager.py:273

Cheers,
Mikal

Hi,

The interval can be managed via the periodic_interval flag in nova.conf,
which is by default 60 sec

Cheers!
