This is an interesting idea. In addition to the creation we will
also need the update. I would prefer that the agents would have one
topic - that is for all updates. When an agent connects to the
plugin it will register the type of operations that are supported on
the specific agent. The agent operations can be specific as bit
masks.<br>
<br>
I have implemented something similar in
<a href="https://review.openstack.org/#/c/9591" target="_blank">https://review.openstack.org/#/c/9591</a><br>
<br>
This can certainly be improved and optimized. What are your
thoughts?<br></div></blockquote><div><br></div><div>Based on your follow-up emails, I think we're now thinking similarly about this. Just to be clear though, for updates I was talking about a different topic for each entity that has its own UUID (e.g., topic port-update-f01c8dcb-d9c1-4bd6-9101-1924790b4b45) </div>

In addition to this we have a number of issues where the plugin does
not expose the information via the standard API's - for example the
VLAN tag (this is being addressed via extensions in the provider
networks feature)<br></div></blockquote><div><br></div><div>Agreed. There are a couple options here: direct DB access (no polling, just direct fetching), admin API extensions, or custom RPC calls. Each has pluses and minuses. Perhaps my real goal here would be better described as "if there's an existing plugin agnostic way to doing X, our strong bias should be to use it until presented with concrete evidence to the contrary". For example, should a DHCP client create a port for the DHCP server via the standard API, or via a custom API or direct DB access? My strong bias would be toward using the standard API. </div>

3. Logging. At the moment the agents do not have a decent logging
mechanism. This makes debugging the RPC code terribly difficult.
This was scheduled for F-3. I'll be happy to add this if there are
no objections.<br></div></blockquote><div><br></div><div>That sounds valuable. </div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div bgcolor="#ffffff" text="#000000">
4. We need to discuss the notifications that Yong added and how
these two methods can interact together. More specifically I think
that we need to address the configuration files.<br></div></blockquote><div><br></div><div>Agreed. I think we need to decide on this at monday's IRC meeting, so we can move forward. Given F-3 deadlines, I'm well aware that I'll have to be pragmatic here :) </div>

The RPC code requires that the eventlet monkey patch be set. This
cause havoc when I was using the events from pyudev for new device
creation. At the moment I have moved the event driven support to
polling (if anyone who reads this is familiar with the issue or has
an idea on how to address it any help will be great)</div></blockquote><div><br></div><div>Sorry, wish I could help, but I'm probably in the same boat as you on this one. </div><div> </div><div>I'm going to make sure we have a good chunk of time to discuss this during the IRC meeting on monday (sorry, I know that's late night for you...). </div>
