<p class="MsoNormal" style="mso-margin-top-alt:auto;margin-bottom:12.0pt"><span style="font-size:10.0pt">Hi All,<br>
<br>
In our OpenStack deployment, API endpoints are defined by using URLs instead of port numbers and HAProxy forwards requests to the right bakend after having ACLed the URL.<br>
<br>
In the case of our object-store service, based on RadosGW, the internal API endpoint is "<a href="https://%3cFQDN%3e/object-store/swift/v1/AUTH_%3ctenant_id%3e" target="_blank">https://<FQDN>/object-store/swift/v1/AUTH_<tenant_id></a>"<br>
<br>
When Ceilometer RadosGW pollster tries to connect to the RadosGW admin API with the object-store internal endpoint, the URL becomes
<a href="https://%3cFQDN%3e/admin" target="_blank">https://<FQDN>/admin</a>, as shown by HAProxy logs. This URL does not match any API endpoint from HAProxy point of view. The line of code that rewrites the URL is this one:
<a href="https://opendev.org/openstack/ceilometer/src/branch/stable/wallaby/ceilometer/objectstore/rgw.py#L81" target="_blank">
https://opendev.org/openstack/ceilometer/src/branch/stable/wallaby/ceilometer/objectstore/rgw.py#L81</a><br>
<br>
What would you think of adding a mechanism based on new Ceilometer configuration option(s) to control the URL rewriting ?<br>
<br>
Our deployment characteristics:<br>
- OpenStack release: Wallaby<br>
- Ceph and RadosGW version: 15.2.16<br>
- deployment tool: OSA 23.2.1 and ceph-ansible<br>
<br>
<br>

Jean-Francois</span><o:p></o:p></p>
