I might have found a bug in Kolla-Ansible (Victoria version) but don't know where to file it.

This is about central logging. In my installation, none of the interesting logs (Nova, Cinder, Neutron...) are sent to Elasticsearch. I confirmed that using tcpdump.

I found that fluentd's config file /etc/kolla/fluentd/td-agent.conf tags these logs with "kolla.*". But later in the file, one finds filters like this:

# Included from conf/filter/01-rewrite-0.14.conf.j2:
<match kolla.var.log.kolla.*.*.log>
    @type rewrite_tag_filter
    capitalize_regex_backreference yes
...
  <rule>
    key     programname
    pattern ^(nova-api|nova-compute|nova-compute-ironic|nova-conductor|nova-manage|nova-novncproxy|nova-scheduler|nova-placement-api|placement-api|privsep-helper)$
    tag openstack_python
  </rule>

If I understand this right, this basically re-tags all nova logs with "openstack_python".

The same config file has an output rule at the very end. I think the intention is to make this a catch-all rule (or "match anything else"):

# Included from conf/output/01-es.conf.j2:
<match *.**>
    @type copy
    <store>
       @type elasticsearch
       host 192.168.122.209
       port 9200
       scheme http

etc.

Unfortunately, the openstack_python tag doesn't match *.**, since it contains no dot.  I fixed this with <match **>. Now I receive all logs, but I am not sure if this is the right way to fix it.

The error, if it is one, is in https://opendev.org/openstack/kolla-ansible/src/branch/master/ansible/roles/common/templates/conf/output/01-es.conf.j2.

If you want me to file a bug, please let me know how.

Bernd.
