nicodemus_ | hello gordc, do you have a moment? I just need to ask a quick question | 15:37 |
nicodemus_ | Is the Ocata gnocchi dispatcher able to choose which archive policy to use when pushing metrics? I remember it to be possible in older versions, specifying the archive policy in the ceilometer config file | 15:39 |
jd_ | nicodemus_: archive policy rules in the answer | 15:40 |
nicodemus_ | jd_, so... the answer would be "no", right? | 15:41 |
jd_ | but… I say it's archive policy rules, not "no"! :) | 15:41 |
jd_ | but yeah IIRC we removed the settings from Ceilometer | 15:42 |
nicodemus_ | thing is, you map a metric to an archive policy, but in the event that two different clients want to push the same metric you have no means to separate metric A from client A versus metric A from client B | 15:42 |
jd_ | client or Ceilometer? | 15:42 |
jd_ | or client that are Ceilometers? | 15:43 |
nicodemus_ | client was not a good choice of word... let's say customer | 15:43 |
nicodemus_ | customer A and customer B want to POST the same metric, but I'd like to have that metric from one customer to use a different archive policy | 15:44 |
jd_ | wah | 15:44 |
jd_ | err I think we never though somebody would do that | 15:44 |
jd_ | +t | 15:44 |
jd_ | let me check if we did remove it | 15:44 |
jd_ | I don't recall exactly | 15:45 |
nicodemus_ | hahah we always have a weird requirement | 15:45 |
jd_ | no we did not removed it | 15:45 |
jd_ | we are planning to deprecate it | 15:45 |
gordc | i don't understand how the same metric would have different policy. | 15:45 |
jd_ | maybe we should not | 15:45 |
jd_ | gordc: different needs? | 15:45 |
jd_ | gordc: from 2 different ceilometers | 15:46 |
*** yprokule has quit IRC | 15:46 | |
gordc | but they are two different metrics... but have the same attributes. | 15:46 |
nicodemus_ | in this specific case, one customer wishes to have monitoring and the other wishes to have just an hourly rating | 15:46 |
nicodemus_ | and we look to remove unnecessary processing from gnocchi | 15:47 |
jd_ | gordc: I don't understand what you don't understand | 15:47 |
gordc | hahah | 15:47 |
nicodemus_ | that means not processing every 10 minutes for the customer that doesn't need monitoring | 15:47 |
jd_ | nicodemus_: so yeah you can do the same thing with ocata | 15:48 |
nicodemus_ | jd_, that's good news | 15:48 |
gordc | yeah i don't understand. if userA pushes cpu_util of vmA and userB pushes cpu_util of vmA. isn't that just same metric, but an archive policy containing two granulariteis? | 15:48 |
openstackgerrit | Julien Danjou proposed openstack/ceilometer master: Revert "deprecate archive policy of Gnocchi dispatcher" https://review.openstack.org/482191 | 15:49 |
gordc | granularities* | 15:49 |
jd_ | gordc: this is not what nicodemus_ says | 15:49 |
jd_ | gordc: ceilometerA pushes cpu_util of vmA for userA and ceilometerB pushes cpu_util of vmB for userB | 15:50 |
nicodemus_ | ^ that's right | 15:50 |
jd_ | but userA wants archive policy low and userB wants high | 15:50 |
gordc | oh. that's just two separate metrics in my mind. | 15:51 |
*** gongysh has joined #openstack-telemetry | 15:51 | |
jd_ | gordc: it is, but you can't do that without having the option for each ceilometer to force their archive policy at metric creation time | 15:53 |
jd_ | archive policy rule won't cover that use case | 15:53 |
gordc | word. | 15:53 |
openstackgerrit | Chason Chan proposed openstack/python-ceilometerclient master: Docs: switch to openstackdocstheme https://review.openstack.org/476757 | 15:54 |
gordc | jd_: your revert only supports scenario where both users are coming from completely separate ceilometer? | 15:56 |
jd_ | gordc: yes…? what's the trap in your question? | 16:03 |
*** lhx_ has quit IRC | 16:03 | |
gordc | jd_: how many people have multiple different ceilometer's running? i imagine it's one ceilometer per region... | 16:05 |
jd_ | gordc: at least nicodemus_ ? | 16:05 |

flwang | gordc: jd_: questions about gnocchi | 21:37 |
flwang | gordc: jd_: does gnocchi support a pluggable transformer for metrics? | 21:38 |
flwang | the background is we're experiencing a performance issue of ceilometer + mongodb | 21:38 |
flwang | so we're planning to gnocchi to improve the API performance when collecting data from ceilometer/gnocchi | 21:39 |
gordc | what does pluggable transformer mean? | 21:39 |
flwang | but we're wondering if we can do it more aggressive | 21:39 |
flwang | gordc: 1 sec, let me show you something | 21:39 |
flwang | gordc: see https://github.com/openstack/distil/blob/master/distil/transformer/conversion.py | 21:40 |
flwang | distil is our billing system | 21:40 |
flwang | now we're collecting data from ceilometer and then wash/transform them into the format we can use for billing | 21:40 |
flwang | so that means Distil needs to call Ceilometer/Gnocchi API to get the metrics, transform them, save in local Distil Database | 21:41 |
flwang | instead of getting the data and saving locally, i'm thinking if we can transform the data at the first place, by Gnocchi | 21:42 |
flwang | especially given now Gnocchi is a general metrics as a service | 21:42 |
flwang | does that make sense? gordc, jd_ ^ | 21:43 |
gordc | flwang: are you just computing the lifecycle of a resource? | 21:43 |
flwang | kind of, another transformer class https://github.com/openstack/distil/blob/master/distil/transformer/arithmetic.py | 21:44 |
gordc | err... i don't really know what context your using these transformer... the arithmetic stuff seems like what gnocchi does already with aggregations. | 21:46 |
*** gongysh has joined #openstack-telemetry | 21:47 | |
gordc | is raw_data the output of running ceilometer sample-list -m meter_name? | 21:48 |
flwang | gordc: yep | 21:51 |
*** vishwanathj has joined #openstack-telemetry | 21:52 | |
gordc | flwang: i'll be honest, i have no idea how start/end related to the raw_data. gnocchi simplest description is roughly equivalent to "ceilometer statistics -m meter --resource_id blah" | 21:57 |
gordc | it does capture lifecycle as well but probably not for the NetworkServiceTransformer you have | 21:58 |
