16:44:13 Uggla thanks elodilles
16:44:20 elodilles thanks too o:)
16:44:31 Uggla #topic vmwareapi 3rd-party CI efforts Highlights
16:44:37 Uggla fwiesel anything for us ?
16:45:07 fwiesel Hi, so I can confirm that the bugfix in oslo.vmware would fix the image upload timeout observed by gibi
16:45:12 fwiesel #link https://review.opendev.org/c/openstack/oslo.vmware/+/982614
16:45:31 Uggla \o/ thanks
16:45:46 fwiesel That's from my side for now... I spend the calmer days looking into some random errors, but nothing to report now.
16:46:17 gibi yeah I'm +1 on the fix
16:46:28 Uggla fwiesel thank you.
16:46:36 Uggla #topic Gibi's news about eventlet removal
16:46:45 gibi o/
16:48:01 gibi no much to report
16:48:20 gibi work ongoing on the console proxies and testing
16:48:51 gibi the PTG etherpad is up to date
16:49:04 gibi we will discuss status and plans there
16:49:08 gibi EOM
16:49:15 sean-k-mooney https://review.opendev.org/c/openstack/oslo.vmware/+/982614 looks indepent of the executor issue we saw in the vmware job so this is just a general urllib3 issue not an eventet oen right
16:50:16 sean-k-mooney im asking because it does not have a bug filed for it and im wodnering if eventlet was masking it
16:51:20 gibi the executor issue was the deadlock on sending dependent tasks to the parent's executor we fixed that in general
16:51:28 gibi this bug apperad after
16:51:44 gibi and was visible as hanging in image tasks in the vmware driver
16:52:13 sean-k-mooney ack so it may have been there but not visable before
16:52:17 gibi yeah
16:52:25 sean-k-mooney i know evently also monkey patches urllib3
16:52:35 sean-k-mooney so that also complciates things
16:52:43 sean-k-mooney ok we can likely move on
16:52:53 Uggla #topic Bug scrubbing

16:53:47 Uggla oops forget to say : Skipping Layos topic as he looks not around and we are a bit late on schedule
16:54:17 Uggla #topic Open discussion
16:54:25 Uggla Uggla: Suggest no meeting next week. 20th April vPTG week.
16:54:38 gibi +1
16:54:54 elodilles +1
16:54:54 Uggla I will notify on the ML too
16:55:36 Uggla any last 5 minutes topic to discuss ?
16:57:08 phildree[m] Hello guys, I am not sure if this is the right place and time to bring this up because i am new to OpenStack, but I have created a spec and am looking for some feedback: https://review.opendev.org/c/openstack/nova-specs/+/984384
16:58:07 Uggla phildree[m], can you add a topic in the ptg etherpad ? then I'll define a slot for you next week.
16:58:32 phildree[m] Ok, thank you :)
16:58:54 Uggla any "prefered" timing ?
16:59:59 phildree[m] Nope
17:00:22 Uggla ok
17:00:27 Uggla so I think we are good.
17:01:00 Uggla time to close, thanks for joining this meeting. Have a nice day/evening and see you next week for the vPTG.

17:01:07 Uggla #endmeeting
17:01:11 fwiesel o/ thanks everyone
17:01:17 elodilles see you next week o/
17:01:24 sean-k-mooney phildree[m]: have you talked to oslo about his
17:01:52 phildree[m] No, this IRC is my first point of contact for now
17:01:56 sean-k-mooney phildree[m]: in generally iw oudl prefer if we removed the if we didnt have to have any aplciation level handchakes
17:02:24 gibi thanks
17:03:21 sean-k-mooney we have some existign rpc pings but anything that makes the conductor comptue messageing nosyier by addign background messages direct hurts scalableity fo nova
17:03:46 phildree[m] sean-k-mooney: Ok, I understand. Maybe handshake is a bit much for what i have proposed, its more like an echo
17:04:11 sean-k-mooney right im saying even adding a echo/ping is protically a scaling issues
17:04:18 phildree[m] sean-k-mooney: I have seen the existing ping but it is not applicable to our usecase (I explained why in the spec)
17:05:00 phildree[m] sean-k-mooney: yes you are totally right, I get that. Any other ideas on how to solve the problem we have been facing?
17:05:30 opendevreview Merged openstack/nova stable/2025.1: Fix fill_metadata usage for the ImagePropertiesWeigher https://review.opendev.org/c/openstack/nova/+/964291
17:05:36 sean-k-mooney i have not read your spec yet but we gerneally perfer to start with the usecase/probelm
17:05:47 sean-k-mooney before going to a feature/design chagne
17:07:01 sean-k-mooney phildree[m]: the prviosu solution which we never implmetned was per binary healthcheck endponts on each nova service
17:08:21 sean-k-mooney phildree[m]: i think teh issue your having is something the outbount rabbit conenction is fucntional
17:08:28 sean-k-mooney but the inbound one is not correct
17:08:49 sean-k-mooney i.e. the compute can call the conductor but the conductor cannot sucessfully call the computes
17:09:14 phildree[m] Yes, we faced this exact issue.
17:09:33 sean-k-mooney do you have the guareented message delivery flag enabled in oslo
17:09:36 phildree[m] I will think about the other approach with individual per binary healthcheck endpoints
17:10:13 phildree[m] That is a good question, which I am not able to answer right now
17:10:13 sean-k-mooney well we didnt impment that or at least we didnt merge it
17:11:11 melwitt bauzas: hi, there are two vtpm related patches that are simple and need a second review if you could get a chance plz https://review.opendev.org/c/openstack/nova/+/978836 and https://review.opendev.org/c/openstack/nova/+/983504
17:11:19 sean-k-mooney phildree[m]: https://docs.openstack.org/nova/latest/configuration/config.html#oslo_messaging_rabbit.direct_mandatory_flag
17:11:25 sean-k-mooney i woudl check you have that set to true
17:11:32 phildree[m] My issues with the per binary healthcheck is that I still need a way to ensure that full communication from conductor to compute (and back) is up and running, which i cannot check without any actual communication, I think
17:11:51 sean-k-mooney phildree[m]: what that will detect is fi the per compute queue is present
17:12:02 phildree[m] Ok very nice, I will look into it, thank you for the infos :)
17:12:18 sean-k-mooney phildree[m]: well the whole point of the per binary healthcheck si to not use rabbit or the conductor
17:12:38 sean-k-mooney it to move the health moditoring out fo that code path to an external http endpoint
17:12:51 sean-k-mooney that you can have prometheous or whatever scrape instead
17:14:45 phildree[m] I get it, and it makes sense, but then there is no way to check the health of the communication (and the underlying infrastructure) between conductor and compute (only the individual binaries)
17:14:45 sean-k-mooney phildree[m]: the direct_mandatory_flag tuns a slient failrue (the messag eis encued to a new queue that nothign is listenting too) into a driect rpc call failure and failure in teh api
17:15:41 sean-k-mooney right today we do that via the resouce update whcih is a push model
17:16:18 sean-k-mooney its worth a dicussion i guess but my main concern is we dont really run perodic form the conductor to monitor the satues of other agents
17:16:49 sean-k-mooney and we try not to do monitoring in general in nova. so this woudl likely need to be confiugrable and off by defualt
17:16:57 sean-k-mooney at least until we know the overhad of it
17:17:58 phildree[m] I think I have to read up on what you have sent first before I may rethink the idea. Thanks a lot for the infos so far, that was very helpfull and a lot less complicated then i thought :)
17:17:58 phildree[m] I have touched many points of what you have brought up, but as I said, I am not yet very familiar with OpenStack so maybe there are some issues I did not anticipate.
17:19:14 sean-k-mooney phildree[m]: one thing we are currently changing
17:19:32 sean-k-mooney is we will nolonger have a slngle rpc listter per compute agent
17:19:47 sean-k-mooney we will now have two becase fo the graceful shutdown work
17:20:06 sean-k-mooney so gmaan woudl likely need to review your prosal in the context fo that work
17:20:24 phildree[m] Ok, that is something very important as this may have implications on my idea
17:20:42 sean-k-mooney with graceful shutdown we will be shutting down 1 of the 2 lstenter until the inprogress operation complete
17:21:02 sean-k-mooney so any kind fo monitoring would likely have to be on the one we dont shutdown
17:22:08 gmaan sean-k-mooney: reading chat
