By default mariadb does not report a hostname when it starts replicating from another server. This means the output of `show slave status` only contains very opaque information:
```
root@pc2007.codfw.wmnet[(none)]> show slave hosts;
+-----------+------+------+-----------+
| Server_id | Host | Port | Master_id |
+-----------+------+------+-----------+
| 171966644 | | 3306 | 180355176 |
| 180367374 | | 3306 | 180355176 |
+-----------+------+------+-----------+
```
If we use puppet to set report_host to the fqdn, then it will show up in the `show slave hosts` table, as well as be available for orchestrator to query.
NOTE: This requires MySQL daemon to be restarted
