catintheroofgordc: sileht guys, hi, is there any insight about if ceilometer supports to push RBD disk metrics ? here's the reference: https://bugs.launchpad.net/mos/+bug/153925314:30
openstackLaunchpad bug 1539253 in Mirantis OpenStack 9.x "Ceilometer: Disk.usage metric is not available for ceph volume. " [Medium,Fix released] - Assigned to Ildar Svetlov (isvetlov)14:30
silehtcatintheroof, yes you need to implement it in KVM14:30
catintheroofsileht: do you have any reference on how to do it ?14:31
silehtcatintheroof, no idea14:31
silehtcatintheroof, the only I know is Ceilometer rely on libvirt that relies on KVM and KVM doesn't provide this information for RBD disk14:31

openstackLaunchpad bug 1457440 in Ceilometer "Compute agent virDomainGetBlockInfo error for instances with RBD backend" [Medium,Triaged]14:39
silehtcatintheroof, maybe I haven't tested recently14:41
silehtcatintheroof, I have just tested: http://paste.openstack.org/show/599417/14:43
silehtcatintheroof, so yes the version of KVM and libvirt in ubuntu 16.04 have this implemented14:43

lhx_gordc, sileht, have you ever beringei?15:05
lhx_do you guys know beringei?15:05
gordclhx_: no, sorry.15:06
silehtlhx_, I have just cross it, but it's a 'inmemory' implementation so it's fast, it doesn't store the data...15:06
lhx_gordc, Facebook made it open source recently as time-series storage15:07
lhx_sileht, yeah, so fast15:08
lhx_with high performance15:08
silehtthey say 'scalable' but it's not 'scalable verticaly or horizontaly'15:08
silehtso I don't got the direction of the scalability ;à15:09
gordclhx_: i hacked gnocchi to write to ramdisk once. it was 'so fast' also :P15:09
silehtI personnaly use it with the 'incoming data' into a tmpfs :) it's fast also15:10
silehtI don't think 'Beringei' and 'Gnocchi' goals are the same15:10
gordcwe need to do our benchmarks on that. :)15:10
silehtI got how they do the scaling part, they do sharding with the client...15:12
lhx_gordc, i guess you can compare them in some aspects, but you can't do quantitative comparison15:13
gordcsileht: like ceph?15:13
gordclhx_: was there something unique it does that we can do as well? idea 'sharing'15:13
silehtgordc, I don't found the detail15:16
gordcsileht: ack. maybe i'll look at it later15:17
lhx_not very clear, just know it has extremely fast query performance in-memory storage and extremely efficient streaming compression algorithm15:18
*** donghao has quit IRC15:20
lhx_the percent of compress data would be higher than 90%15:20
lhx_seems better than gnocchi15:21
*** donghao has joined #openstack-telemetry15:21
lhx_can also integrate with Grafana15:22
lhx_s/integrate/be integrated15:22
*** faizy has quit IRC15:22
gordclhx_: i imagine you need some context to compression percentage. if i compress 1000 '1' and 1 '0', the compression will be amazing also. :)15:24
silehtI think I will test it to see how it works more in detail15:24
lhx_gordc, lol, you are right, we should do quantitative comparison15:27
lhx_sileht, sounds great!15:29

nicodemus_hello18:22
nicodemus_Suppose I want ceilometer-agent to push an extra key in the samples. This extra key needs to be accepted by gnocchi, but I don't need to have it on the resource_type definition (since this value will go to generic)18:24
nicodemus_How could I make gnocchi to accept it if it's not on the resource_type definition? I'm imagining adding an "if" somewhere in indexer/sqlalchemy.py, but don't know exactly where...18:26
nicodemus_my guess is that here: https://github.com/openstack/gnocchi/blob/master/gnocchi/indexer/sqlalchemy.py#L747 the create_resource method gets the resource definition, is that so?18:30
gordcnicodemus_: i don't think generic stores any attributes so i'm not sure what you're asking is possible18:45
gordcyou can ask on ML. i dont know the answer myself and not sure anyone else is online anymore.18:46

harlowjagordc jd__ the polling rate of different pollsters is all configurable right?19:32
harlowjahttps://github.com/openstack/ceilometer/blob/master/etc/ceilometer/polling.yaml  though sets everything to 10 minutes?19:33
harlowjai guess most people change that :-P19:33
gordcharlowja: yeah, it's the default.19:35
gordci think we might have actually asked whether people changed that in a prior survey... let me check19:35
harlowjakk19:36
gordcbut yeah 10 minutes is long.lol19:36
harlowjafor certain pollsters it may be, for certain others it might be ok :-P19:39
*** rbak has joined #openstack-telemetry19:40
gordcharlowja: we asked what ideal poll interval was in survey back in Oct2015, ~65% said 5-10 minutes, ~27% said 1-5min19:47
harlowjafor all the pollsters?19:47
harlowjado people usually set the globally ?19:47

nicodemus_excuse me gordc, I got sidetracked. Let me rephrase the question: when/where are a resource's attributes checked when the dispatcher tries to POST something to gnocchi?20:19
nicodemus_Imagine a new resource that needs to be created, and the dispatcher has X amount of attributes mapped to that resource in the gnocchi_resources.yaml file. The dispatcher tries to POST to gnocchi API, how does gnocchi verify that said POST contains an extra key?20:20
silehtnicodemus_, it should return 400 for invalid input20:23
nicodemus_sileht, it does indeed20:23
nicodemus_but... I'm trying to avoid returning that 400 error20:23
silehtnicodemus_, we use volouptuous lib to check input, and we write in the code we want this behavior20:24
silehtnicodemus_, do you want to ignore the extra key ?20:24
nicodemus_yes20:25
nicodemus_I need to get this extra key and use it for something else, with gnocchi not complaining about it20:25
nicodemus_is the input check done here? https://github.com/openstack/gnocchi/blob/e11e7b4f438e474f78355a02bf17b54068370931/gnocchi/rest/__init__.py#L10920:26
