<br>
I think what you are looking for is mostly this:<br>
<a href="https://github.com/oVirt/vdsm/blob/master/lib/vdsm/api/vdsm-api.yml" rel="noreferrer" target="_blank">https://github.com/oVirt/vdsm/<wbr>blob/master/lib/vdsm/api/vdsm-<wbr>api.yml</a><br>
<br>
The best way to see what the traffic is is to disable SSL. The<br>
postgres database is installed and accessible using the postgres user<br>
(the engine user is not allowed to access it directly).<br>
<br>
You might also be interested in the vdsm fake project we use as node<br>
simulator. Its readme will tell you exactly how to do this:<br>
<a href="https://github.com/oVirt/ovirt-vdsmfake" rel="noreferrer" target="_blank">https://github.com/oVirt/ovirt<wbr>-vdsmfake</a><br>
<br>
I wrote an article some time ago that explained how to setup a<br>
development environment without real hosts:<br>

<br>
Might I ask what you goal is?<br>
<br>
Best regards<br>
