idegtiarov | eglynn: Thanks for looking thru patch, answering your question I can say that Ilya Tyaptin is going to prepare patch set with migrations for HBase. So we can merge this patch now or wait for patch set from Ilya, but I don't know when it will be done. | 11:28 |
eglynn | idegtiarov: would it make more sense to reverse the ordering? | 11:29 |
eglynn | idegtiarov: migration first, change seperator second | 11:29 |
eglynn | (depends somewhat on Ilya's progress) | 11:30 |
idegtiarov | eglynn: If we really have any data that is stored into HBase with old separators it will be more sense to have migration patch first I think. | 11:30 |
*** palar_ has joined #openstack-ceilometer | 11:31 | |
eglynn | idegtiarov: yep, I agree | 11:32 |
eglynn | idegtiarov: can you check with ityaptin on the rate of progress on the migrations? | 11:32 |

_nadya_ | eglynn: I'm afraid 'migration' is not for HBase... Of course it can be implemented with a special map-reduce job. Do we really need this now? I will investigate it today anyway | 11:41 |
eglynn | _nadya_: yes, I think if we're changing the storage format, don't we need to migrate the old data? | 11:42 |
eglynn | _nadya_: (if not via a sql-a style migration script, then via more other kinda of mapping) | 11:43 |
eglynn | _nadya_: (in the mongodb case, if we change the storage format, we map from the old to the new) | 11:43 |

*** Alexei_987 has joined #openstack-ceilometer | 11:43 | |
ityaptin | eglynn, _nadya_, I'm trying to parse and put data from old format rows to new. And delete old rows. | 11:45 |
ityaptin | eglynn, _nadya_, It's not fast approach, but in happybase we have not so many variants. | 11:47 |
*** vrovachev has joined #openstack-ceilometer | 11:47 | |

ityaptin | eglynn, first patchset for this I can send to review tomorrow. But I don't believe what now we may have big troubles with changing row format. | 11:52 |
eglynn | ityaptin: cool, thanks! | 11:52 |
ityaptin | eglynn, base problem, how i understand with natural sorting data in tables, because in scan, get requests we ignore table row | 11:54 |
eglynn | ityaptin: I don't fully understand your question ... but perhaps _nadya_ can clarify that for you? | 11:54 |
*** shakamunyi has quit IRC | 11:58 | |
ityaptin | eglynn, sorry, I write too slow( I try to say what we save order of data in responses for requests even if we use old data and new data in same db | 11:58 |

_nadya_ | ityaptin: let's investigate this. I understand what you are asking. | 12:03 |

ityaptin | Summary, I try to say, what we may not save order of 'migration' -> 'changing delimeters patch', because we will not have issues with old and new data in tables. | 12:06 |

mspreitz | Can anybody explain why my Ceilometer has network.incoming.packets.rate samples? I see nothing about that in my Ceilometer entry_points.txt nor the debug loggin in central.log | 17:12 |
*** shang has quit IRC | 17:12 | |
ildikov | mspreitz: it comes from a transformer configured in pipeline.yaml: https://github.com/openstack/ceilometer/blob/master/etc/ceilometer/pipeline.yaml#L128 | 17:14 |
ildikov | mspreitz: more information about pipelines: http://docs.openstack.org/developer/ceilometer/configuration.html#pipelines | 17:15 |
mspreitz | Interesting... my entry_points has stuff for ...bytes.rate but not packets.rate, and my pipeline specifies derivation of rate for both bytes and packets! | 17:16 |
mspreitz | Why does my config specify two sources for ...bytes.rate? | 17:17 |
ildikov | mspreitz: which two sources do you mean? | 17:17 |
mspreitz | In my Ceilometer egg, entry_points.txt has, e.g., network.incoming.bytes.rate = ceilometer.compute.pollsters.net:IncomingBytesRatePollster (and same for outgoing). And pipeline.yaml says how to derive network.incoming.bytes.rate from network.incoming.bytes | 17:18 |
ildikov | mspreitz: but it's still one source | 17:20 |
ildikov | mspreitz: or maybe I didn't get your concern | 17:20 |
mspreitz | ildikov: my entry_points.txt says network.incoming.bytes = ceilometer.compute.pollsters.net:IncomingBytesPollster --- and that, all by itself, produces network.incoming.bytes Samples... | 17:21 |
mspreitz | My entry_points.txt also says network.incoming.bytes.rate = ceilometer.compute.pollsters.net:IncomingBytesRatePollster.. so I suppose that all by itself is sufficient to produce network.incoming.bytes.rate Samples ... | 17:22 |
mspreitz | And then my pipeline gives another way to produce network.incoming.bytes.rate Samples | 17:22 |
*** sbfox has quit IRC | 17:23 | |
ildikov | mspreitz: ah, ok, I see now | 17:25 |
ildikov | mspreitz: good question, currently I cannot answer this question, I would need to check the code | 17:26 |
mspreitz | ildikov: thanks, that would be helpful | 17:28 |
ildikov | mspreitz: I need to run soon | 17:28 |
ildikov | mspreitz: can you check back tomorrow within UTC office hours? | 17:29 |
mspreitz | It's not an immediate blocker, an answer later would be great. mspreitz@us.ibm.com | 17:29 |
mspreitz | I'll try | 17:29 |
mspreitz | thanks | 17:29 |
ildikov | mspreitz: cool, if it's not that urgent, then I will drop you a mail, if I could get there to check this | 17:30 |
mspreitz | thanks, any clues will be appreciated | 17:30 |
ildikov | mspreitz: sure, I will check tomorrow and let you know about the details | 17:31 |

DinaBelova | fabiog, eglynn, folks, some follow-up questions after the call | 17:38 |
DinaBelova | I decided to move them here as we were running out of time actually | 17:38 |
DinaBelova | fabiog, eglynn - that's sad Marco left us during the discussion - as I feel something uncomfortable about the taskflow+scalability | 17:39 |
DinaBelova | eglynn - please correct me if i'm awfully wrong - but as far as I know taskflow is really not distributed thing to be used | 17:39 |
*** fnaval has quit IRC | 17:39 | |
eglynn | DinaBelova: do you mean that you have doubts about the scalability of taskflow? | 17:39 |
DinaBelova | yes, indeed | 17:39 |
DinaBelova | eglynn - I understand the openstacky patern of extracting things to the libs, etc. to be reused | 17:40 |
DinaBelova | but actually as I'm not the expert here (I mean taskflow) - and I see no way to use it not only in the active/passive mode | 17:40 |
DinaBelova | because tooz currently (at least as I understood while surfing its code) is only leadership election thing - well, okay, probably we may make it better, etc. But actually I see no job around making taskflow something distributed | 17:41 |
DinaBelova | that's why fabiog's solution is something I can see not only HA, but scalable as well | 17:42 |
DinaBelova | and something with taskflow - no - at least with the understanding I have currently | 17:43 |
eglynn | DinaBelova: why is taskflow relevant? | 17:43 |
eglynn | DinaBelova: neither approach uses taskflow | 17:43 |
DinaBelova | eglynn, I mean the Julien's idea not to store tasks info in the ceilo DB, but use the taskflow to manage the tasks | 17:44 |
DinaBelova | and here I see no way to make this scalable in the closest future - but actually I might be awfully wrong here with some terrible misunderstanding | 17:45 |
DinaBelova | eglynn, am I? Really I want to solve this mystery and central agent HA+scalability asap - because this feature is really important for us (well, for all of us I guess) | 17:47 |
eglynn | DinaBelova: IIUC fabiog just included tasklow in that preso because he wanted to see how his notion of database-based locking would map onto taskflow | 17:47 |
mspreitz | I have a couple of quick questions about https://github.com/openstack/ceilometer/blob/master/ceilometer/agent.py#L109 ... | 17:47 |
eglynn | DinaBelova: so just to re-iterate, neither solution requires taskflow | 17:48 |
mspreitz | First and foremost, can one really just gin up an admin context like that? No real auth token? | 17:48 |
nsaje | DinaBelova: tooz is not just leader election. Tooz provides distributed coordination primitives. Those include leader election, group membership and distributed locking currently | 17:49 |
DinaBelova | eglynn, mmmm.... well, as far as I understood that was one of the greatest disagreement Julien had with Alexey and then with Fabio | 17:49 |
DinaBelova | nsaje, a-ha! | 17:49 |
nsaje | DinaBelova: and it's entirely scalable. Currently it has Zookeeper and Memcached backends available, both of which are scalable | 17:50 |
nsaje | DinaBelova, in the future, we might only need AMQP even | 17:50 |
DinaBelova | nsaje, so the services running in one group might be fully active/active | 17:50 |
nsaje | DinaBelova, exactly | 17:50 |
eglynn | DinaBelova: here's the proposal https://review.openstack.org/#/c/111978/1/specs/juno/central-agent-partitioning.rst | 17:50 |
DinaBelova | eglynn, yes, I went through it quickly before the presentation | 17:51 |
eglynn | DinaBelova: when we talked about the alternative on that call just now, that's it what we meant ^^^ | 17:51 |
eglynn | DinaBelova: i.e. not the prior discussion at summit with Alexey etc. | 17:51 |
DinaBelova | eglynn, no-no, I kept in mind the mid-cycle discussion | 17:52 |
DinaBelova | and I guess I misunderstood current tooz functionality | 17:52 |
fabiog | DinaBelova: I guess Taskflow now is out of the picture | 17:52 |
DinaBelova | fabiog, yes, okay | 17:52 |
fabiog | DinaBelova: Tomorrow I want to understand what Tooz adds compared to just use Zookeper | 17:53 |
eglynn | DinaBelova, fabiog: yep https://review.openstack.org/#/c/111978/1/specs/juno/central-agent-partitioning.rst only requires shared knowledge of the other agent's existence | 17:53 |
*** aviau has quit IRC | 17:53 | |
eglynn | DinaBelova, fabiog: i.e. no central authority to distribute tasks such as taskflow | 17:54 |
fabiog | eglynn: so the agents are talking to each other or asking tooz? | 17:54 |
nsaje | fabiog, tooz is just an abstraction and enables you to use different backends | 17:54 |
nsaje | fabiog, so you're not bound to zookeeper | 17:54 |
DinaBelova | fabiog, nsaje - so actually we're communicating with zookeeper for now | 17:54 |
fabiog | nsaje: if the solution relies on a clustering technique I don't need the abstraction | 17:54 |
eglynn | DinaBelova, fabiog: was that lack of a taskflow dependency not clear from the gerrit proposal and the discussion on the call? | 17:55 |
nsaje | DinaBelova, fabiog: No, we're using distributed coordination primitives. Backend is irrelevant | 17:55 |
fabiog | nsaje: I just use the one I like | 17:55 |
gordc | fabiog: i think the idea is that what you like isn't necessarily the solution for everyone. | 17:55 |
nsaje | fabiog, DinaBelova: I suggest we take this discussion to gerrit :) | 17:55 |
fabiog | eglynn: is that last time you proposed the usage of Taskflow and mentioned that the Job Board would be used to know the status of all the jobs (agents) | 17:55 |
gordc | so that abstraction allows everyone ability to choose. | 17:56 |
fabiog | eglynn: I guess this is what created the confusion | 17:56 |
DinaBelova | eglynn, just to make sure - as I clearly remember Julien was strictly about the taskboard usage | 17:56 |
DinaBelova | fabiog, exactly | 17:56 |
DinaBelova | eglynn, I mean TaskBoard in the TaskFlow | 17:56 |
*** renatoarmani has quit IRC | 17:56 | |
*** ildikov has quit IRC | 17:56 | |
nsaje | DinaBelova, here are the two specs we're talking about, so we're on the same page: https://review.openstack.org/#/c/101282/5 and https://review.openstack.org/#/c/111978/1 | 17:57 |
eglynn | DinaBelova, fabiog: but again, the prior discussions about potentially using taskflow isn't really relevant to the current state of either proposal, or? | 17:57 |
fabiog | eglynn: I never wanted to use taskflow, but at that time it seemed a requirement to use this library as part of the Openstack ecosysten | 17:58 |
DinaBelova | eglynn, if so, that makes much more sense for me - I'm really sorry I misunderstood current tooz proposal - it was something linked with the taskflow as a technique in my mind | 17:58 |
DinaBelova | I mean, due to the previous endless discussions | 17:59 |
fabiog | eglynn: if that requirement is gone, then I don't need to investigate further since I don't believe Taskflow is suited for HA | 17:59 |
DinaBelova | nsaje, yeah, thanks | 17:59 |
DinaBelova | fabiog, ++ | 17:59 |
fabiog | eglynn: I believe you guys have reached the same conclusion :-) | 17:59 |
eglynn | fabiog: the preference was to use the prior art in the ecosystem, *if* this was relevant to the solution | 18:00 |
eglynn | fabiog: as opposed to "you must use taskflow for the sake of using taskflow!" ;) | 18:00 |
DinaBelova | eglynn, ok, so it looks like fabiog and /me missed the taskflow disappearing from the tooz proposal | 18:01 |
eglynn | DinaBelova: well it was never in the proposal on gerrit | 18:01 |
eglynn | IIUC | 18:01 |
eglynn | but yeah, it featured in the initial discussions | 18:02 |
eglynn | (at summit and mid-cycle) | 18:02 |
DinaBelova | eglynn, yes, you're right. mid-cycle thing tricked me much | 18:02 |
* DinaBelova needs to go through the https://review.openstack.org/#/c/111978/1/specs/juno/central-agent-partitioning.rst one more time for sure | 18:02 | |
DinaBelova | at least I have time before tomorrow :) | 18:03 |
eglynn | fabiog, DinaBelova: /me needs to drop for another call now | 18:03 |
eglynn | (already very late) | 18:03 |
eglynn | chat more tmrw | 18:03 |
DinaBelova | eglynn, oh, sorry | 18:03 |
eglynn | DinaBelova: np! | 18:03 |
DinaBelova | eglynn, see u | 18:03 |
fabiog | eglyn: good night and thanks for your time | 18:03 |
gordc | fabiog: unrelated but have you seen this spec: https://github.com/openstack/oslo-specs/blob/master/specs/juno/taskflow-redis-jobs.rst | 18:03 |
nsaje | yeah, good night guys! | 18:05 |

gordc | eglynn: wasn't it backported to stable/havana? or are you asking if it shouldn't have been? | 19:30 |
eglynn | gordc: I was more asking if it need to be backported to stable/havana ... i.e. if the bug existed in the havana timeframe? | 19:31 |
gordc | https://review.openstack.org/#/c/101799/ | 19:31 |
