boris-42eglynn hi08:08
boris-42eglynn something wired is happening with this patch08:08
boris-42eglynn https://review.openstack.org/#/c/103610/08:08
*** nacim has joined #openstack-ceilometer08:08
boris-42eglynn I mean take a look at rechecks08:09
boris-42eglynn I mean I even don't know why this is happaning=)08:09
eglynnboris-42: py26 is timing out http://logs.openstack.org/10/103610/1/check/gate-ceilometer-python26/32b2b87/console.html08:09
boris-42eglynn so it's common issue?08:10
eglynnlooks like the same timeout error that's been plaguing the tests since the oslo-messaging switchover08:10
boris-42eglynn maybe rebase can somehow help?08:10
eglynnboris-42: a rebase on what?08:11
boris-42eglynn that patch08:11
boris-42eglynn this one https://review.openstack.org/#/c/103610/08:11
eglynnboris-42: I don't really see how rebasing could help08:11
boris-42=)08:11
boris-42eglynn I remember that one time it helped )08:11
eglynnsileht: are you around?08:12
boris-42eglynn it was related to some merge crap08:12
boris-42eglynn e.g. it was merged successfully but with some magic changes=)08:12
eglynnboris-42: yeah, well rebase it anyway for good hygiene08:12
boris-42eglynn and is this ok https://review.openstack.org/#/c/103420/ ?08:12
eglynnboris-42: ... but that looks like the eventlet issue once again08:12
boris-42eglynn eventlet strikes again! =)08:13
nsajeeglynn boris-42 : this might be fixed after the oslo.messaging 1.3.1 release08:13
boris-42nsaje ok nice08:13
boris-42nsaje btw not sure08:13
*** alexpilotti has joined #openstack-ceilometer08:13
boris-42nsaje in gates we are using from master oslo.messaging as I know08:13
eglynnboris-42: OK your TODO makes a bit more sense now, ready to fly08:14
boris-42eglynn and yes I am going to make plugins in future=)08:14
boris-42eglynn for collecting keystone stuff08:14
eglynnboris-42: https://github.com/openstack/ceilometer/blob/master/requirements.txt#L2008:14
boris-42eglynn hm but at least in dsvm stuff08:14
boris-42eglynn we are using oslo.messaging from master08:15
boris-42eglynn not sure about py jobs08:15
eglynnboris-42: the timeout failure is in the py26/27 jobs08:15
silehteglynn, o/08:16
*** safchain has joined #openstack-ceilometer08:17
eglynnsileht: hey, welcome back :)08:17
silehteglynn, thanks08:17
eglynnsileht: ... just a heads-up that we're still seeing the oslo-messaging/eventlet timeouts e.g. http://logs.openstack.org/10/103610/1/check/gate-ceilometer-python26/32b2b87/console.html08:18
eglynnsileht: ... but nsaje also found an interesting bug in the oslo-msg fake driver that may be related08:19
eglynnsileht: ... FYI https://bugs.launchpad.net/oslo.messaging/+bug/134208808:19
silehteglynn, looks like a bug I have introduced when I have fixed the reason timeout issue of our tests in oslo-msg...damm08:20
eglynnsileht: sound plausible that it could be the root cause of the more recent failures?08:21
*** _nadya_ has quit IRC08:22
silehteglynn, yes that depending of who create the fake exchange point if eventlet schedule the server first the test fail, if the client is scheduled first the test pass08:24
silehteglynn, before my fix when the server start first, the test can pass, but no it always fail ...08:25
silehtno/now08:25
eglynnsileht: a-ha, OK ... so hopefully we'll have a olso-msg 1.3.1 release today to confirm in the gate08:25
eglynnsileht: the other thing is just to confirm that we can declare vistory on https://blueprints.launchpad.net/ceilometer/+spec/dedicated-alarm-database for j2?08:26
eglynnsileht: ... looks like everything that's needed is already landed? :)08:26
silehteglynn, I have pull out of my big patch every thing I can, now I have to prepare the final one08:27
silehteglynn, all reviews I have pull out of my bug patch have been merged08:28
eglynnsileht: a-ha, cool, so the final one is do-able for juno-2 do you think?08:28
eglynnjuno-2 == July 24th08:28
silehteglynn, I need to check if I have no hurry thing to do I have missed during my holiday first, but it looks reasonable, I hope to submit the latest patch before monday afternoon08:31
boris-42eglynn btw I have one question08:31
*** inc0 has joined #openstack-ceilometer08:31
boris-42eglynn I was asked from community to cover one more use cases related to profiler08:31
boris-42eglynn e.g. they would like to use "CLI"08:31
boris-42eglynn and get profiling info08:32
boris-42eglynn cinder --profile volume create 108:32
eglynnsileht: cool, monday would be tight to get the patch shepharded thru gerrit before thurs, but should be doable if the gate doesn't explode on us08:32
boris-42and it will print what is that (trace id)08:32
boris-42eglynn so they would like to be able to retrieve this data08:33
*** ildikov has quit IRC08:33
boris-42eglynn and currently they can only retrieve notification lists08:33
boris-42eglynn so could we add some command in ceilometer python client that will call osprofiler.parse_notifications()  that transforms this list to the tree structure ?08:33
eglynnboris-42: why have a dependency on osprofiler in the ceilo client?08:34
boris-42eglynn yep that is not super cool08:34
eglynnboris-42: i.e. why not just write a simple python-osprofilerclient?08:34
boris-42eglynn but I don't know where to put this parser08:34
boris-42eglynn ou08:35
boris-42eglynn btw08:35
boris-42eglynn not so bad idea08:35
boris-42eglynn I have a lot of stuff that can be put there08:35
eglynnboris-42: cool :)08:35
boris-42eglynn thanks for idea08:35

eglynnnsaje: thanks for the docco patch!09:44
eglynnnsaje: ... though on reading your description of the "Aggregator transformer", I got a sinking feeling :(09:45
eglynnnsaje: ... seems the logic is broken for cumulative meters, or?09:45
DinaBelovaeglynn, btw, /me in progress of retention testing in opentsdb :D the thing is that retention param for the timeserie is counted with 'days' so the exact result I'll get ~11pm local time :D09:46
*** yatin has quit IRC09:47
nsajeeglynn: let me check the code09:47
DinaBelovaeglynn, I hope to publish the draft before end of week :)09:47
eglynnDinaBelova: a-ha, interesting, so multiples of 1 day is the only way to set the rentention policy in opentsdb?09:48
DinaBelovaeglynn, at least it looks so now09:48
nsajeeglynn: could be, though I must admit the purpose of this transformer is not crystal clear to me09:48
eglynnnsaje: https://github.com/openstack/ceilometer/blob/master/ceilometer/transformer/conversions.py#L24309:48
DinaBelovaeglynn, that feature is still developing (for the 2.0 and higher), I'll try to ping some opentsdb folks to understand what they're going to do with it further09:49
nsajeeglynn: I don't see what the use case for it would be with a cumulative meter09:49
DinaBelovaeglynn, as 2.x is smth new and currently developing in the opentsdb09:49
eglynnnsaje: ... so I'm guess that should first check if the meter type is cumulative and if so do a straight assignment: self.samples[key].volume = self._scale(sample)09:49
eglynnDinaBelova: cool09:49
eglynnI'm *guessing that should first ...09:50
nsajeeglynn: ah, that could work, yes, do you want me to file a bug and submit a patch?09:50
eglynnnsaje: that would be great :) ... thanl you sir!09:50

DinaBelovaeglynn, do you know something about central agents HA status? :)13:40
eglynnDinaBelova: fabiog is on vacation13:40
DinaBelovaeglynn, who's working on it?13:40
DinaBelovafabiog - yes, but he was going to ignore tooz that time..13:40
DinaBelovadoes he plan to impl it as it was supposed to?13:40
*** yatin has quit IRC13:41
eglynnDinaBelova: we had a long, long discussion about it at mid-cycle on Friday afternoon13:41
eglynnDinaBelova: that was my recommendation13:41
DinaBelovaeglynn, yes, I remember this discussion - but I don't remember his answer here..13:41
eglynnDinaBelova: ... he'll come back with an updated BP when he returns from vacation13:41
DinaBelovaeglynn, cool, that's nice :)13:42
DinaBelovaeglynn - does he have vacation this week only or some time too?13:42
eglynnDinaBelova: I don't know exactly, but I think he said 2 weeks13:43
eglynnDinaBelova: ... i.e. this week and last week13:43
DinaBelovaeglynn, oh, ok13:44
ildikoveglynn: DinaBelova: yeap, he said 10 days, so two weeks, he should be available again next week13:44
*** inc0 has quit IRC13:45
DinaBelovaildikov, eglynn - cool! I just want to say, that if he'll need any help here, central agent HA is quite important for me, and as j2 has passed, I'm really full of energy to help him - or finally do that myself if it'll be impossible for him :)13:45
eglynnDinaBelova: cool, I think having a second contributor involved would be a good think13:46
eglynngood *thing13:46
*** psharma has quit IRC13:46
DinaBelovaeglynn, yeah, exactly... I completely miss his vacation from my mind (my fault...) that's why I became really worried..13:47
DinaBelovaif it'll be done at all :D13:47
jd__eglynn: did you spin up that Gnocchi instance?13:48
eglynnDinaBelova: so if you listened in on does mid-cycle discussions, did my description of horizontal versus vertical slicing thru' the target resource sets make sense to you?13:48
*** amalagon has quit IRC13:49
DinaBelovaeglynn, yes, it still seem logical for me - as it'll make uniform load on all the agents running13:49
eglynnjd__: actually I did, but I've also screwed up something dumb in my swift setup :( ... digging into it now13:49
eglynnjd__: I should have something to report shortly13:49
jd__eglynn: no pressure13:50
eglynnDinaBelova: cool :)13:50
DinaBelovaeglynn, as far as I remember idea was to give unifromly pack of tasks to be done to each agent with different target resources13:51
DinaBelovaeglynn, not by resource - but multiple resources for each agent13:51
*** pradk has joined #openstack-ceilometer13:51
DinaBelovaeglynn, are my rememberings true? :)13:51
eglynnDinaBelova: yep, so instead of agent1 doing all the SNMP polling, agent2 doing all the neutron polling, ...13:52
DinaBelovaeglynn, yes, ok - I asked just to be sure everything is ok with my memory :)13:53
eglynnDinaBelova: we have agent1 doing some SNMP polling & some neutron, agent2 doing some neutron polling & some SNMP, ... etc13:53
eglynnDinaBelova: the idea was to drive that slicing via the discovery extensions grabbing from the taskboard (or equivalent mechanism for allocation)13:53
DinaBelovaeglynn - that also won't allow to have some time when pack of snmp tasks was not processed at all during some 'fault-tolerant' time13:53
DinaBelovaeglynn, that's even more HA that deviding by resource13:54
DinaBelovadividing*13:54
DinaBelovathe only problem we may meet here is with efficient zookeeper working, but that's solvable imho (my experience with zookeeper tells me that it likes separated nodes for its work, that's not really comfortable for the small envs - although it was a while ago, now zookeeper is more tolerant)13:56
DinaBelovaanyway, that'll be defined during the work :d13:57
eglynnDinaBelova: yep, so smaller allocations of resource type, means say all SNMP polling isn't interrupted during a failover13:57
DinaBelovaeglynn, exactly13:57
eglynnDinaBelova: yeah I'm not an expert on ZK, and suitability for small as well as large deployments13:57
eglynnjd__: has there been much adoption of tooz d'ya know? (outside of ceilo)13:58
* eglynn just wondering about the experiences with deploying/packaging ZK13:59

*** fnaval has quit IRC14:04

jd__but harlojw might have the answer14:08

amalagoneglynn: yeah...jd pointed that out too - ok, thanks, I'll try reworking it14:44
eglynnamalagon: now that we've got our noses in the same code ...14:45
eglynnamalagon: note also jd__'s comment on "So that means that all custom aggregates are based on mean?"14:45
*** nati_ueno has quit IRC14:45
eglynnamalagon: ... so that was the point I was making before about the custome aggregator *itself* calling down to the storage driver to get the raw data14:45
amalagoneglynn: yes, that is my bad - it should be calling raw data since granularity is 1 (the aggregation='mean' is not doing anything)14:46
eglynnamalagon: ... as only the custome aggregator itself knows whether same the mean-of-means is OK, or whether say mean-of-raw is needed14:46
eglynnamalagon: ... so how about pushing that responsibility to call down to the storage driver into each custom aggregator?14:47
eglynnamalagon: ... the pecan.request.storage object could be passed as param to compute()14:48
amalagongood point14:48
cdentbiab14:48
eglynncool14:48
amalagonalthough, just to quibble...14:50
amalagonI think that all the custom aggregators are taking in raw data as of now14:50
amalagon... I forgot what the rest of my argument was14:51
amalagonnm14:51
eglynnamalagon: :)14:51
eglynnamalagon: you could be correct though14:51
eglynnamalagon: my thought was that *some* aggregations could possibly optimize if they know they don't need the most granular data available14:52
eglynnamalagon: but I'm not sure how realistic that notion is14:53
*** _nadya_ has joined #openstack-ceilometer14:53
*** _nadya_ has quit IRC14:53
amalagoneglynn: the optimization would come from not calling the raw data?14:54
eglynnamalagon: grabbing fewer datapoints from the storage backend, getting it to roll-up before pushing that data back to gnocchi14:55
eglynnamalagon: ... so say moving-window average was generally calculated as a mean-of-means14:55
amalagonbut then if the other custom aggregates are going to need the raw data (ewma, moving-variance)14:55
eglynnamalagon: sure, so each one can decide itself what it needs14:55
eglynnamalagon: because the call down to the storage driver could occur *with* the custom aggregator itself14:56
eglynnamalagon: ... as opposed to being done for it by the API layer14:56
amalagoneglynn: ah yes, sorry...I keep on thinking the aggregates are working on the same retrieved data, but it has to be re-retrieved for each request..I have a very persistent wrong mental picture14:57
eglynnamalagon: think of each API request as a kind of clean slate14:57
amalagongotcha14:58
amalagonI think I'm convinced now; I'll try working on this a bit15:00
eglynnamalagon: excellent :)15:01
eglynnamalagon: ... if you wanna to play around a bit with those ideas in code, just push a new patchset & ping me whenever you're ready for another review pass15:01

EmilienMcdent: we need first to fix javelin15:48
EmilienMso I did a couple of patches with features15:48
EmilienMbut the basic does not work well in the OpenStack CI15:48
cdentHave you seen the recent changes from Sean that add a -d arg to javelin?15:49
EmilienMcdent: looking15:52
EmilienMcdent: the imgdir?15:52
* cdent nods15:53
EmilienMcdent: I missed that one, good to know15:53
cdentthat seems pretty important as it helps ground any paths that the resources.yaml needs15:53
EmilienMcdent: did you already played with javelin2 ?15:54
EmilienMyeah right15:54
cdentyes, have you seen: https://review.openstack.org/#/c/102354/15:54
