ildikovrainmantea_: vcpu comes from notifications07:47
*** boris-42 has quit IRC07:47
rainmantea_so then yes i dnt think i get any meters by polling07:48
ildikovrainmantea_: cpu, some disk and network meters are collected by polling07:48
ildikovrainmantea_: and cpu_util is calculated from the cpu samples by using a transformer07:48
ildikovrainmantea_: do you see that log entry for every polling cycle?07:49
rainmantea_no i dont think isee any log entry for polling cycles07:50
rainmantea_<ildikov>this is my first implementation cycle of openstack so im just following up basic doc on setup07:51
*** nellysmitt has joined #openstack-ceilometer07:53
ildikovrainmantea_: by default the polling cycle is set to 10 mins07:54
ildikovrainmantea_: and the cpu_util transformer needs two values in order to calculate, so you need to wait two cycles long to get that sample07:54
ildikovrainmantea_: do you have the cpu samples present or those are missing too?07:55
rainmantea_those are missing too07:58
ildikovrainmantea_: do you have a running instance now on your compute node which is in active state?07:58

*** Longgeek has quit IRC09:38
mc__eglynn: If I can you support with logs and data, let me now know. otherwise I would call it a day :)09:39
eglynnmc__: so the core of the issue AFAICS from the logs is that the repeat_actions attribute is embedded in the combination_rule attribute of the POST'd alarm representation09:42
eglynnmc__: (as opposed to being a top-level alarm attribute, as it should be)09:42
eglynnmc__: I haven't figured out yet if this is a python-ceilometerclient or heat bug09:42
mc__okay. can I provide more logs from anything?09:43
eglynnmc__: I'll update ask.openstack.org when I get to the bottom of the source of the issue09:43
eglynnmc__: actually the heat engine log exerpts showing the creation of the non-combo alarms would be useful09:44
mc__aye thank you. I'll add the log of the other non combo alarms in ask.openstack.org soon.09:46
eglynnmc__: thank you sir!09:46
eglynnmc__: actually I'm pretty sure it's a Heat bug, just confirming whether it's just on stable/icehouse or master also09:48
eglynnmc__: I'll file the appropriate in the launchpad once I've pulled everything together, and cc'd you on the bug09:48
*** Longgeek has joined #openstack-ceilometer09:49
eglynnmc__: yep, its on Heat master too AFAICS09:50
eglynnmc__: here's the culprit https://github.com/openstack/heat/blob/master/heat/engine/resources/ceilometer/alarm.py#L35009:51
*** exploreshaifali has quit IRC09:51
ildikovrainmantea_: can you paste the compute node version of the ceilometer.conf file too?09:52
*** admin0 has joined #openstack-ceilometer09:52
eglynnmc__: (has the effect of embedding the repeat_actions attribute in the combination rule, instead of being a top-level alarm attribute)09:52
eglynnrainmantea_: I see your ping off-channel09:52
eglynnrainmantea_: are you running the ceilometer compute-agent on the compute node? ... are there errors in the compute-agent logs?09:53
ildikoveglynn: an earlier entry: the error on the compute node : WARNING ceilometer.transformer.conversions [-] dropping sample with no predecessor: (<ceilometer.sample.Sample object09:54
ildikovrainmantea_: is that intended that the qpid_hostname is not set in the ceilometer.conf file to the same value as in case of nova?09:55
ildikovrainmantea_: is it set on the compute hosts in the ceilometer.conf file?09:56
eglynnildikov: that log warning is OK if there's only a single such warning for cpu_util on the first polling cycle after agent startup09:57
eglynnildikov: (the cpu_util needs a prev and curr on the cpu sample to be calculated)09:57
eglynnildikov: (so can't be calculated normally until the 2nd polling cycle)09:58
ildikoveglynn: I know, I explained that after or at least I tried to :)09:58
ildikoveglynn: but this was the answer I got to a question similar to yours earlier09:59
eglynnildikov: a-ha, k10:00

jd__I'm not really bothered by that, or that means the project as a whole has another problem and it just detected it efficiently ;)11:49

eglynnjd__: nice one, thank you sir!11:51
eglynnjd__: do you see the alarm evaluation part being in-tree as the key problem in ceilo?11:52
eglynnjd__: my own view is that it's the storage approach and API11:52
jd__eglynn: a key problem? no at all, just something that'd help us having a better code base I'd say, that's all11:53
jd__the key problem for now is storage and the API that's why I'm focusing on Gnocchi :)11:54
eglynnjd__: yep, agreed :)11:54
jd__Gnocchi which has a lot of patches in the review queue *cough* *cough*11:54

justinsbES support sounds really cool; I've always been impressed by the ELK stack so would be good to get that in OpenStack15:12
justinsbWorking on it, wanted to learn more about Cassandra and seemed a great match for ceilometer data.15:13
justinsbI'm not sure I have enough data that I actually _need_ Cassandra15:13
gordcjustinsb: yeah, there are some issues with it but i think it has promise (for events specifically)15:13
justinsbBut it is nice to know that if my basement expanded to multiple geographically distributed basements I could still meter it!15:14
gordcjustinsb: ok cool cool. yeah i looked partially at cassandra for events but i think some of the talks i watch mentioned a preference of ES over cassandra. so i stopped.15:14

gordci think if this was a year or so ago, it'd be easier to get another backend in... now we're at point where we have a lot of options/proposals that idea of adding another backend is starting to wane.15:16
*** zul has joined #openstack-ceilometer15:16
justinsbES is much better for allowing richer queries, I think.  Cassandra is probably stronger at bigger cluster sizes, because it is less consistent.15:16
*** ddieterly has joined #openstack-ceilometer15:17
justinsbYes, it seems like a lot of development is shifting to Gnocchi.  Are there other proposals/directions also?15:17
gordcjustinb: gnocchi will be the direction to store our time series metrics... seems like a logical step. we have time-series measurements...store it in db that are designed specifically for that.15:19
gordcjustinsb: events and alarms will live separately and for the most part are open-discussion.15:20
gordci'm starting to work on events but i'm open to ideas.15:20
justinsbI would suggest that Cassandra is well-designed for time series, even if not specifically designed for it!15:21
justinsbI think having rich events (and alarms) in ES would be a great idea; rich searching here seems very valuable15:22
gordcjustinsb: i'm not sure how cassandra fits into gnocchi design... but you may want to look at it... we have a plugin design there as well so you could add cassandra as an alternative to influxdb or opentsdb15:23
justinsbI think that's my next step, once I get this patch landed.15:24
justinsbI'm just not sure I'm ready to go to the bleeding-edge of Openstack... it's pretty rough out there15:24
gordcOpenStack's tagline: "it's pretty rough" lol15:25

dhellmannjustinsb, gordc : the bad wheel for wsme should be gone now, and we're waiting for new packaging instructions to land before creating a new release15:43
