lhx__sileht, seems kafka driver of oslo.messaging supports pass the whole payload12:47
lhx__relative to ceilometer12:47
lhx__https://github.com/openstack/ceilometer/blob/master/ceilometer/publisher/kafka_broker.py#L93-L9512:47
silehtlhx__, yes :)12:47
silehtlhx__, I think in pike we should deprecate this and tell people to use notifier:// with oslo.messaging kafka driver12:48
lhx__sileht, haha, I'm studying olso.messaging and think how to replace kafka publisher ;)12:49
lhx__sileht, I have considered it more complicated, but should be simple than i thought12:51
lhx__s/simple/simpler12:51
silehtlhx__, thought oslo.messaging the message on kafka will just have a new envelope around, in the 'payload' entry you will get the ceilometer sample/event as before12:52
silehtthe topic name will change too :)12:52
lhx__sileht, what does topic name change to? no longer 'ceilometer'?12:55
silehtlhx__, it will become ceilometer.sample I think12:55
*** chlong has joined #openstack-telemetry12:56
lhx__sileht, maybe event, lol12:56
silehtlhx__, the part before the dot is configurable in oslo.messaging, but not the part after the dot12:56
silehtor maybe ceilometer.info12:56
lhx__sileht, thank you for these hints12:57
silehtyour welcome12:59

openstackgerritMerged openstack/gnocchi master: s3: set maximum length for s3_bucket_prefix option  https://review.openstack.org/43037714:22
silehtakrzos, we didn't hardcode anything14:25
cdentjd__: just sent you my latest interview response. This one may make less sense than some of the others. If some clarifications are needed, let me know.14:26
akrzossileht: got it, but if i say spawned 100 processes per controller and i had 3 controllers, so 300 metricd workers, that should work or will there be issues with say database or rabbit or redis with running that many?14:26
* akrzos didn't try yet but wasn't sure if we would hit some other limit/dependency14:27
gordci don't think it should fail. some of the workers might not do anything (because of scheduling 'logic')14:27
*** sudipto_ has joined #openstack-telemetry14:29
*** sudipto has joined #openstack-telemetry14:29
silehtakrzos, redis is limited by the number of file descriptors it can open on the server14:30
silehtakrzos, I hope the distro have set it to unlimted :)14:30
*** nadya has joined #openstack-telemetry14:30
silehtceph limit looks like ~100000, so we are good here too14:32
silehtmaybe more14:32
*** mengalong_ has joined #openstack-telemetry14:32
silehtand mysql is 150 \o/, but metricd should not use it14:33

openstackgerritMerged openstack/gnocchi master: gabbi: use history  https://review.openstack.org/43165414:53
gordcakrzos: sorry, i mis-used 'worker', i meant agent. we have a pretty naive partitioning logic. basically, each agent registers to group and gets assigned a number says, i have 100 workers. so i'll grab 16 * <#workers> items.14:53
*** rbak has joined #openstack-telemetry14:54
*** dave-mccowan has joined #openstack-telemetry14:54
gordcso if agent gets assigned one of larger numbers, say it 3, it will look at the 3rd grouping of 16 * <#workers>14:54
gordcand if you won't have that many objects to work on it, it will do nothing.14:54
*** donghao has quit IRC14:55
gordcthat would be easier to describe in a diagram... not good with words.lol14:56
*** iceyao has quit IRC14:56
gordcwe're basically partitioning a single bucket into smaller buckets of 16*<#workers in agent> and then each agent grabs one of these smaller buckets... it's not really a concern for you if you're testing 10,000VM and their set of metrics.14:58
gordconly thing you'll notice is, if the backlog drops, load is less distributed... eventually only agent will be doing anything.15:01

akrzosanother quick question, is getting measures (gnocchi measures show...) the same as aggregation (gnocchi measures aggregation)16:29
akrzosthem seem to return the same  but maybe it's because i'm passing parameters like granularity and aggregation method16:29
akrzosok just passed the metric id16:30
akrzosand it's the same16:30
akrzosare they the same thing?16:30
openstackgerritHanxi Liu proposed openstack/ceilometer master: Ship YAML file to /usr/share  https://review.openstack.org/41230916:31
akrzoslooks like you can do multiple metrics with aggregation16:31
openstackgerritHanxi Liu proposed openstack/ceilometer master: Support extended declaring exchanges  https://review.openstack.org/42241116:31
openstackgerritHanxi Liu proposed openstack/ceilometer master: Support loading multiple meter definition files  https://review.openstack.org/42959016:32
silehtakrzos, yes when you aggregate metrics, if only one metric is found, you will get the same result16:33
akrzosgot it so aggregation is for putting multiple metrics together rather than getting a single "series" of measures froma  specific metric16:34
silehtakrzos, the shortcut is here: https://github.com/openstack/gnocchi/blob/master/gnocchi/rest/__init__.py#L1610-L161516:35
