sanfernalexchadin, Hi08:20
alexchadinhi sanfern08:21
sanfernThere are many granularity supported by Gnocchi, which data need to be collected by watcher?08:22

alexchadinsanfern: each strategy requires its own metrics08:26
alexchadinsanfern: you can find required metrics in strategies documentation08:26
*** diga has quit IRC08:29
sanfernalexchadin, ok, for example for basic consolidation  there are two metrics we are looking - compute.node.cpu.percent, cpu_util. Can we provide gnocchi measures show --resource-id b0e1c862-d0f8-4622-b4f8-93c019d1125e --aggregation sum cpu_util08:38
alexchadinsanfern: yes, but 'mean' or 'min' aggregation functions are more applicable here. I propose to ask 'granularity' from admin to specify his policy. Take a look at https://review.openstack.org/#/c/438530/1/watcher/datasource/gnocchi.py08:40
alexchadinsanfern: of course, 'granularity' should be specified in conf opts08:40

vincentfrancoisealexchadin: hi09:37
*** dtardivel has joined #openstack-watcher09:39
alexchadinvincentfrancoise: What do you mean by correctly formatted? I think, it makes sense to check type of start_time/end_time attributes (gnocchi applies only datetime type)09:39
vincentfrancoisealexchadin: I didn't know whether gnocchi needs a timestamp, a iso-formatted string or a datetime object which is why I was saying that having a validator telling whether the format is correct or wrong would be helpful09:41
alexchadinvincentfrancoise: BTW, it isn't correct to check is start_time <= end_time cause if I call 'gnocchi measures show --resource-id 204b2f8c-7dd8-484c-aeca-6af9e4aa2583 cpu_util --start 2017-02-28T09:38:00+00:00 --stop 2017-02-28T09:33:00+00:00'09:45
alexchadinvincentfrancoise: I get09:45
alexchadin| timestamp                 | granularity |         value |09:45
alexchadin| 2017-02-28T09:00:00+00:00 |      3600.0 | 3.92711458274 |09:45
alexchadinvincentfrancoise: It is feature of TS-DB, granularity related to archive policy09:46
vincentfrancoiseHum, that weird to specify an interval that is not possible in theory09:47
vincentfrancoisegiving an interval that finished even before starting sounds kind of crazy to me09:48
vincentfrancoisebut if it works... leave it as is09:48
alexchadinvincentfrancoise: there are no intervals :( gnocchi collect samples from ceilometer and set points with defined granularity09:48
alexchadinvincentfrancoise: I have two granularity for cpu_util: each minute and each hour09:49
alexchadinso, hour's granularity is aggregation point09:49
alexchadinvincentfrancoise: It is predefined policy of gnocchi, named medium09:50
vincentfrancoiseyes but then your query says that you want to aggregate the points between start_time and end_time isn't it? This is the part that I find counter-intuitive09:50
openstackgerritSanthosh Fernandes proposed openstack/watcher-specs master: Gnocchi support in Watcher  https://review.openstack.org/43726109:51
alexchadinvincentfrancoise: there is aggregation point, 9:00, and given values (38 and 33 minutes) are between 9 and 10 hours, so they are related to 3600 granularity.09:55
alexchadinvincentfrancoise: I agree, this is brainstorm :)09:56
vincentfrancoisealexchadin: so yeah if you just make sure that end_time and start_time are datetime objects, that should be enough then09:57
alexchadinvincentfrancoise: and it isn't intuitive, but if admin needs time-series DB then he has to know all features of this kind of DB09:57
vincentfrancoiseif specified of course09:57
alexchadinvincentfrancoise: yeap, of course09:57
