Hi Steve, thanks for your response. I set report_inteval = 20 but still one minute between the updates of the available resources of my compute nodes (or at least. in this interval they are written to the database).
n-cpu.log shows; 2014-06-27 06:59:21.051 DEBUG nova.openstack.common.loopingcall [-] Dynamic looping call sleeping for 20.00 seconds from (pid=8710) _inner /opt/stack/nova/nova/openstack/common/loopingcall.py:130 but n-cond.log 2014-06-27 07:02:16.421 DEBUG nova.openstack.common.loopingcall [-] Dynamic looping call sleeping for 60.00 seconds from (pid=8665) _inner /opt/stack/nova/nova/openstack/common/loopingcall.py:130 I went through nova.conf again but have no idea which parameter I should change since I tried all which make sense for me (they are listed in my first mail). Has anybody an idea how to change the update interval in which free resource of the compute nodes are written into the database?
