<div>Hello Fabrice,</div>
<div><br>
</div>
<div> 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.</div>

<div class="">Hello Fabrice,<br class="">
<br class="">
I think the easiest way would be to set the affinity for each<br class="">
controller/infrastructure host using 'rsyslog_container: 0' as seen in the<br class="">
following section of the install guide:<br class="">
<a href="http://docs.openstack.org/developer/openstack-ansible/install-guide-revised" class="">http://docs.openstack.org/developer/openstack-ansible/install-guide-revised</a><br class="">
-draft/configure-initial.html#affinity<br class="">
<br class="">
</div>
</div>
</blockquote>
ok, i look at this.</div>
<div><br class="">
</div>
<div>Actually (first deploy with a dedicated log server) , i have:</div>
<div>./scripts/inventory-manage.py -G</div>
<div>rsyslog_container<span class="Apple-tab-span" style="white-space:pre"> </span>
|<span class="Apple-tab-span" style="white-space:pre"> </span>log1_rsyslog_container-81441bbb</div>
<div><br class="">
</div>
<div>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:</div>
<div><br class="">
</div>
<div>log_hosts:</div>
<div> log1:</div>
<div> affinity:</div>
<div> rsyslog_container: 0</div>
<div> ip: 172.29.236.240</div>
<div><br class="">
</div>
<div>Is that right ?</div>
<div><br class="">
<blockquote type="cite" class="">
<div class="">
<div class=""> Next, you should add your actual logging hosts to your<br class="">
openstack_user_config as seen here:<br class="">
<a href="https://github.com/openstack/openstack-ansible/blob/master/etc/openstack_de" class="">https://github.com/openstack/openstack-ansible/blob/master/etc/openstack_de</a><br class="">
ploy/openstack_user_config.yml.aio#L122-L124<br class="">
<br class="">
Be sure to comment out the rsyslog-install.yml line of<br class="">
setup-infrastructure.yml, and be sure that you make any necessary<br class="">
modifications to the openstack-ansible-rsyslog_client role. Modifications<br class="">
may not be necessary, depending on your needs, and you may be able to<br class="">
specify certain variables in user_variables.yml to achieve the desired<br class="">
results.<br class="">
<br class="">

In openstack-ansible-rsyslog_client, the template 99-rsyslog.conf.j2 use :</div>

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