Dear lists, Hi I have recently noticed of this link to customize configurations to be overridden [Thanks to michal nasiadka]: https://docs.openstack.org/kolla-ansible/latest/admin/advanced-configuration... but i have some doubts in regards! The docs says /etc/kolla/ config/<< service name >>/<< config file >> (Ex. /etc/kolla/config/nova/nova-scheduler.conf) let's say i want to change interval to 30sec (* 'interval: 30'*) in *'/etc/kolla/ceilometer-central/polling.yaml'* file: as i understood, i need to create a file in *'/etc/kolla/config/ceilometer-central/polling.yaml'* and copy all the contents of * '/etc/kolla/ceilometer-central/polling.yaml'* into it ( *or just the change?*) and then change just the *interval from 300 to 30 .* Am I doing Right? ( because there was no [DEFAULT] section available in the polling.yaml file ....) After doing the same for all the desired files, then i need to do prechecks and deploy? kolla-ansible -i /etc/kolla/all-in-one prechecks kolla-ansible -i /etc/kolla/all-in-one deploy Thanks
