nati_uenohi is that possible to connect ceilometer and elasticsearch ?01:04
nati_uenoor is there any related bps?01:04

lakspacenati_ueno: I am not a ceilometer committer or expert but I am curious about the use cases you have in mind.01:11
nati_uenolakspace: yeah, i just think it is great if we can use kibana with ceilometer with elastic seach query01:13
lakspacenati_ueno: I see. So you want to be able to discover data based on some search terms.01:13
nati_uenolakspace: yes. also it is great if we could integrate kibana with horizon01:14
lakspacenati_ueno: hmm. FWIW, I am one of the engineers working on https://github.com/rackerlabs/blueflood.01:16
lakspacenati_ueno: We are thinking about using elastic search for related use cases.01:16

shardyeglynn: around?13:39
eglynnshardy: yep13:39
shardyhey eglynn13:39
eglynnhey13:39
shardyCan you spare a moment to check out a ceilometer-related patch we're discussing in #heat atm please?13:39
shardyhttps://review.openstack.org/#/c/4369813:39
eglynnshardy: looking now13:39
shardyWe're trying to understand why the ceilometer API can't handle "-" characters in this case13:40
shardywant to ensure we're not fixing the bug in the wrong project ;)13:40
dhellmannshardy: I'm not aware of any reason our API would reject : or - in group_id vlaues13:41
dhellmannshardy: it's certainly not on purpose13:41
shardydhellmann: humm, iiinteresting, thanks :)13:41
eglynnshardy: yes, I remember swann bringing the issue here originally13:42
eglynnshardy: so then I pointed out that the ':' was problematic for the ceilo-api service13:42
*** dina_belova has joined #openstack-metering13:43
eglynnshardy: the reason for that was the way the ceilo uses AST to eval the query strings13:43
dhellmanneglynn: why is : significant?13:43
shardyeglynn: Ok, so it's the : not the - that's the issue?13:43
dhellmanneglynn: if the query includes a type, that eval should be disabled13:44
eglynnshardy: the ':' is taken as significant in the ast.literal_eval13:44
eglynndhellmann: a-ha, yeah just noticed that in the code13:44
dhellmannthe ast guessing stuff is only enabled if no type is provided13:45
dhellmanntoo clever?13:45
eglynndhellmann: so just setting the type to string should suffice?13:45
dhellmannyes, that should do it13:45
flwangeglynn: ping13:45
eglynnshardy, dhellmann: k, let me confirm that13:45
eglynnflwang: yep?13:45
flwangmay I ask you a question about alarm actions?13:46
dhellmanneglynn: we should have a bug for this still, the evaluation code shouldn't do math like that13:46
eglynndhellmann: what math do you mean?13:46
dhellmanneglynn: I thought the problem was 10-1 would come out as 9, no? or is the : the real problem?13:46
dhellmannand if it's the :, what does *that* do?13:46
eglynndhellmann: the eval code is just translating the alarm's matching metadata into the query on the statistics API13:47
*** manderson has joined #openstack-metering13:47
eglynndhellmann: some of the metadata set by heat included an embedded ':'13:47
swanneglynn, shardy: Hi, the ':' is always a problem BUT I notice in some case the '-' is problematic too.13:47
dhellmannswann: what does "problematic" *mean* though? what *happens*?13:47
swann  WARNING [wsme.api] [31823184] Client-side error: Unexpected exception converting WWW-Layer-4a80714f-0232-4580-aa5e-81494d1a4147-uolhh25p5xxm to the expected data type Unset.13:47
eglynnswann: sounds like the literal_eval failing similarly to the ':' case13:48
swanndhellmann: the alarm evaluator receive a 40013:48
flwangeglynn: based on current alarm action implement, seems it's only an url/target to send the notifications, is it?13:48
dhellmannswann: was the value being evaluated that long identifier starting with "WWW"?13:48
eglynnflwang: yep, RESTy webhhook or logging actions13:49
swannWWW -> is the name of a stack13:49
dhellmannhaha, ok13:49
dhellmannthat string produces a "SyntaxError" in the eval code, and we only catch ValueError13:50
dhellmannso that's a bug in ceilometer, someone please file a ticket13:50
shardyswann: Can you raise a bug with this info please?13:50
dhellmannnevermind, I'll open it, I want to describe the fix anyway13:51
shardydhellmann: Ok, thx, can you let me know the number pls, so I can link it from Heat bug #121584013:51
flwangeglynn: got, but I can't really understand why. Because I assume the notification should be listened by the interested consumer instead of sending the notification to the address, pls correct me13:51
eglynndhellmann: hmm, can the alarm evaluator assume that the alarm matching metadata is always intended to be a string?13:52
dhellmannhttps://bugs.launchpad.net/ceilometer/+bug/122173613:53
eglynnflwang: not sure what you mean by "notification should be listened by the interested consumer"13:53
shardydhellmann: thanks13:53
eglynnflwang: the notification is sent to the consumer in the form of a http POST13:53
dhellmannshardy: should I tag that as impacting heat, too?13:53
eglynnflwang: did you expect it over AMQP or some other delivery mechanism?13:53
dhellmannshardy: oops, I didn't notice you already had a bug, we could have just used that one :-)13:54
*** zaneb has joined #openstack-metering13:54
flwangeglynn: actually, I'm thinking if you can make it more open, such as change the element of actions list as a dict/json13:54
shardydhellmann: I'll just link your bug from the existing one if that's easier13:55
dhellmannshardy: sounds good13:55
eglynnflwang: what do want to achieve?13:55
eglynn*you want13:55
flwangsuch as { "url": "http://xx/deleteimage", "method": "delete", "params": {"a":"foo"}}13:55
flwangeglynn: i'm thinking if the action can be more open-ended13:56
shardyThanks for the assistance all :)13:56
flwanginstead of just POST without any info13:56
eglynnflwang: interesting suggestion, but currently it's a simpler mechanism pased on POST with a fixed payload13:56
eglynnflwang: there is info13:56
flwangeglynn: so we assume the payload includes the info and the real action should be taken by the notifications consumer, is it?13:57
eglynneglynn: the poayload includes the alarm_id, prev and curr state, reason string13:58
eglynnflwang: ^^^13:58
eglynnflwang: then the consumer does whatever it needs to do with that13:58
eglynnflwang: for example heat autoscaling might decide to scale up or not13:59
flwangeglynn: yep, I see. so we do not really want to take the "real" action, right?13:59
flwangeglynn: if so, why we don't just send the notifications with a specific topic the the AMQP?14:00
eglynnflwang: if by "real action" you mean the actual scale-up in the heat AS case, then no ceilometer shouldn't initiate that directly14:00
eglynnflwang: too much logic embedded in the action, such as cool-down, sanity limits etc.14:00
eglynnflwang: a RESTful call allows us to use pre-signed URLs (AWS stylee)14:01
flwangeglynn: got it, make more sense14:01
*** tong|2 has joined #openstack-metering14:01
eglynnflwang: but direct AMQP notification would be easy to add as another notification scheme14:01
flwangeglynn: so what's the direction for alarm in Icehouse?14:01
*** lexx_ has joined #openstack-metering14:02
eglynnflwang: well we'll discuss that before and at summit obviously, still an open question as of now14:03
flwangeglynn: got it. thanks for patient :)14:04
