Hello Fabrice, You should also set the rsyslog affinity to 0 for the infra_hosts. I’m not sure if the affinity is necessary for the log hosts, but I don’t think it will hurt. I recommend trying a few different ways and verify the corresponding openstack_inventory.json file to ensure it meets your requirements.

Actually (first deploy with a dedicated log server) , i have: ./scripts/inventory-manage.py -G rsyslog_container | log1_rsyslog_container-81441bbb So, from what you write, not to create a log_container on the log server, i can modify my openstack_user_config.yml to be: log_hosts: log1: affinity: rsyslog_container: 0 ip: 172.29.236.240 Is that right ? Next, you should add your actual logging hosts to your openstack_user_config as seen here: https://github.com/openstack/openstack-ansible/blob/master/etc/openstack_de ploy/openstack_user_config.yml.aio#L122-L124 Be sure to comment out the rsyslog-install.yml line of setup-infrastructure.yml, and be sure that you make any necessary modifications to the openstack-ansible-rsyslog_client role. Modifications may not be necessary, depending on your needs, and you may be able to specify certain variables in user_variables.yml to achieve the desired results. In openstack-ansible-rsyslog_client, the template 99-rsyslog.conf.j2 use : *.* @{{ hostvars[server]['ansible_ssh_host'] }}:{{ rsyslog_client_udp_port }};RFC3164fmt I will test to ensure the IP is that from log1. If yes, no more modification is needed. Thanks again. Regards As always, make sure you test these modifications in a non-production environment to ensure you achieve the desired results.

We deploy openstack-ansible (mitaka 13.1.2 release) on our infrastructure with for convenient and no risk a vm for syslog server role. That is ok. But now if i want to use our centralized syslog server ? What i need is to set ip address of our existing server to the rsyslog client (containers + metal) and of course configure our rsyslog.conf to manage openstack template. So: - no need to create on the log server a lxc container (setup-hosts.yml: lxc-hosts-setup, lxc-containers-create) - no need to install syslog server (setup-infrastructure.yml: rsyslog-install.yml) How can i modify my openstack-ansible environment (/etc/openstack_deploy, env.d, conf.d, openstack_user_config.yml, user_variables.yml, playbook ?) the most transparent manner and that permits minor release update simply ? Thanks.
