samueldmqis it correcto to say "At the service level, OpenStack has native support for API level interoperability, certifying clouds via the RefStack program."14:27
samueldmqthis allows heterogeneous clouds running the same service API versions to fully interoperate14:29
openstackgerritMonty Taylor proposed openstack/openstacksdk master: WIP Collect request stats
samueldmqand then it comes to sdk providing an upper abstraction layer for supporting multiple service (nova-net vs neutron) and versions of the smae service (keystone v2 and v3)14:29
mordredsamueldmq: it's ... the optimistic way of saying it, yes14:35
samueldmqmordred: but that's what refstack does, correct?14:36
samueldmqyou mean optimistic because I am putting so much of the glory in sdk I guess14:37
mordredsamueldmq: no - I mean optimistic about RefStack :)14:50
samueldmqmordred: oh14:50
mordredsamueldmq: but I think what you're saying is the intent - and my pessimistic side just sees the bugs14:51
samueldmqwhat does it do in practice? just run tempest tests against clouds and reports results?14:51
samueldmqmordred: bugs.. for example? I need to know more downsides of it14:52
mordredsamueldmq: so you could say all of the above, but then also that sdk's abstraciton layer does what you say it does - and also works around bugs/holes in the interoperability that refstack aims to provide14:52
mordredsamueldmq: well - places where refstack doesn't have a story for something yet - or where people can't agree that a given feature should be covered by refstack certification14:52
mordredsamueldmq: at the sdk level we can provide a consistency quickly - while aligning different operating clouds might take a bit longer14:53
samueldmqso refstack's intent was to standardize?14:54
samueldmqmordred: that's very interesting... standardizing things that are already alive don't work well. literature and experience shows that14:55
samueldmqalso - standards translates into cutting some use cases, and flexibility :-)14:56
mordredsamueldmq: yes - that's right - and you're exactly right14:58
mordredsamueldmq: refstack started well after there were already many production deployments14:59
mordredso it has to take a conservative approach14:59
samueldmqoh well, that's a good story to be written... thanks!!15:00
mordredsdk also started after many production deployments - so it was able to look at what reality was, and then provide an abstraction on top of that to hide differences that exist due to refstack not existing in the beginning15:00
mordredsamueldmq: \o/15:00

mordredShrews: incidentally, in writing tests for the statsd patch, I actually discovered a bug that was lurking in the existing code18:07
mordredShrews: also - I have tests now18:07
openstackgerritMonty Taylor proposed openstack/openstacksdk master: WIP Collect request stats
mordredShrews, tobiash: ^^ it still needs docs added ... and tobiash, I'd love feedback on the metric names and labels (obviously it's not immediately useful if we don't decided to expose that directly in nodepool - but since you're using things already, I figureyou've got good context)18:12
tobiashmordred: what is the openstack_http_requests supposed to be?18:27
mordredtobiash: the equiv of the task counter18:27
mordredtobiash: so what you're translating to nodepool_task now18:28
tobiashmordred: then I think it should be a counter, not a gauge18:28
mordredtobiash: ok - the counter docs said something about resetting on restarts - was I just understanding that wrong?18:28
mordredtobiash: ah - I see! (found better docs)18:29
mordredand I agre18:29
mordredand good - because I find spelling gauge very hard18:29
*** bobh has quit IRC18:29
tobiashthat's the reference of the prometheus metric types18:30
tobiashmordred: in statsd this is probably a counter too?18:30
mordredtobiash: yah18:31
tobiashgauge is not very useful for aggregating stuff, it should only be used if you are interested in the current value of something like current quota usage18:31
mordredyah - makes sense18:32
tobiashwith counters instead you can do things like calculating rates per any time interval18:32
tobiashmordred: I think using a histogram however is a good choice18:34
tobiashfor the timers18:34
tobiashespecially if you want to aggregate and calculate quantiles of more than one series you *need* historgrams instead of summaries18:36
tobiashsome background info on that:
tobiashit's really interesting18:37
Shrewsya know, i was thinking about stats stuff (since it seems to be all the rage this week)... we could just let folks configure the statsd keys themselves via config file (at least in nodepool).18:38
Shrewsthat probably makes less sense in sdk18:39
Shrewswhere there can be lots of them18:39
Shrewsbah, silly thinking18:39
Shrewsmordred: can we please not add both statsd and the prometheus stuff in a single review?18:41
openstackgerritMonty Taylor proposed openstack/openstacksdk master: WIP Collect request stats
mordredtobiash: updated to counter18:45
mordredShrews: sure - once I get the docs written, I'll split it up18:45
Shrewsmordred: actually, it's not that overly burdonsome here18:45
mordredShrews: I tink that test file should have all the things we need to do further tests - I put in things to add the statsd and prometheus content to details on failure - cause otherwise it's like "1 doesn't match None" and you're like WTF???18:46
mordredShrews: that said - the stastd fixture starts a thread - and when I added it just to the base test case I wound up hitting too many open files :)18:47
mordredwhich - might be a thing we want to look in to in general, as that tells me something isn't properly getting shut down - but it only shows up when you've got a bazillion tests like we do in sdk18:47
Shrewsmordred: weird18:50
tobiashmordred: regarding openstack_http_requests I'd even add the response code as a label19:04
kmallocmordred: so.. about to land some pymemcache awesomeness to oslo.cache19:06

mgagneI'm currently using python-openstackclient and performing "openstack port show <UUID>" on a non-existing port. I found with --debug that if GET /v2.0/ports/<UUID> returns a 404, GET /v2.0/ports is performed instead which can be *very* costly if you happen to have a LOT of ports or are an admin. Is there anyway to improve that?19:58
*** mriedem has joined #openstack-sdks19:59
kmallocmgagne: it would require a flag or something to not perform a list to "find" a port. this is a behavior for "get name or id" type thing that we typically do20:07
kmallocmgagne: it's to handle the case of passing a name instead of an id and having it magically work20:07
mgagnekmalloc: yes, if a UUID like name is found, would it be reasonable to not perform a full list?20:07
kmallocso something like --id <uuid> might need to be implemented so it doesn't do an id then name20:07
mgagneor are people crazy to name their ports with UUID?20:07
kmallocpeople name everything with uuids because operators often dynamically generate that stuff20:08
kmalloci see it all the time with projects/users20:08
kmallocID is UUID X, name is UUID Y20:08
mgagneso you have != but both are UUIDs? crazy stuff20:08
kmalloci wouldn't be surprised in ports or servers or anything20:08
kmallocwelcome to insanity20:09
kmallocit's unfortuantely the norm20:09
mgagnecan we have OS_INSANE=0 then? :D20:09
* kmalloc would rather just do a --id and --name explicit flags20:09
kmallocand throw a warning "hey, the get_name_or_id functionality is going away"20:10
kmallocbut i don't have a lot of say in that part20:10
mgagneok, at least I got an explanation20:10
kmallocthat is a guess fwiw20:11
kmalloci didn't look at the code20:11
kmallocbut it sure sounds like what we do elsewhere20:11
mgagneyea... I'm sure it's nothing like that because it uses find_port which I guess support both id and name at the same time.20:12
kmallocyep, so basically the same concept though20:13
